What determines an atom’s chemical properties quizlet?
The chemical properties of an element, are determined by the number of protons in the nucleus. This number of protons is called the atomic number. The mass of the atom, its atomic mass, depends upon the sum of the number of protons and the number of neutrons present in the nucleus.
What determines an element’s chemical properties?
Valence electrons determine the chemical properties of an element, or how the valence electrons of one element are shared or traded with valence electrons of other elements to create new molecules.
What determines an atom’s identity and chemical properties?
Explanation: The number of electrons, in turn, determines the chemical properties of the atom. Protons contribute to the mass of an atom and provide the positive charge to the nucleus. The number of protons also determines the identity of the element.
What part of the atom determines how the atom reacts chemically?
The number of protons in the nucleus determines which element it is. However, the number of electrons in the outer shell, i.e. the number of valence electrons, determines the chemical reactions that the element can participate in.
What determines the type of atom?
The primary sub-atomic particle is the proton, because the number of protons inside an atom determines which type of atom it is. For example, all atoms that have 8 protons in the nucleus are oxygen atoms. All atoms that have 6 protons are carbon atoms.
What part of the atom determines the chemical properties or reactivity?
The number of protons in the nucleus determines which element it is. However, the number of electrons in the outer shell, i.e. the number of valence electrons, determines the chemical reactions that the element can participate in.
Which particle is responsible for the chemical properties of an atom?
The number of protons inside a nucleus must equal to the number of electrons outside of the nucleus. This number determines all the chemical properties of the atom, which governs the behaviors of all matters in our world.
What is an element determined by?
number of protons An element is defined by its number of protons. Varying the number of neutrons will change the isotope of an element and varying the number of electrons will create an ion, but changing the number of protons changes the identity of the element itself.
Which part of the atom determines the name of the atom and why?
Explanation: The identity of the element is determined by the number of protons, which are positively charged, massive nuclear particles. The number of protons in a nucleus is given by Z , the atomic number.
Which part of an atom determines its chemical behavior?
The position of the outermost electrons is key in determining the behavior of an atom.
What determines chemical reactivity?
The number of electrons in the outermost shell of an atom determines its reactivity. Noble gases have low reactivity because they have full electron shells. Halogens are highly reactive because they readily gain an electron to fill their outermost shell.
What property of an atom allows you to determine which element it is on the periodic table?
Atomic number: The number of protons in an atom's nucleus is referred to as the atomic number of that element. The number of protons defines what element it is and also determines the chemical behavior of the element.
How does an atom react chemically depends?
How an atom reacts chemically depends on how willing it is to share electrons with others.
Which of these particles determines the element’s identity?
1 Answer. The proton determines the identity of an element.
What determines the chemical and electrical properties of an atom?
A neutral atom has an equal number of protons and electrons so that the positive and negative charges exactly balance. Since it is the electrons that determine how one atom interacts with another, in the end it is the number of protons in the nucleus that determines the chemical properties of an atom.
What determines the type of an atom?
The primary sub-atomic particle is the proton, because the number of protons inside an atom determines which type of atom it is. For example, all atoms that have 8 protons in the nucleus are oxygen atoms. All atoms that have 6 protons are carbon atoms.
Which part of the atom determines how the atom behaves chemically and its reactivity?
Elements are made of atoms, and the structure of the atom determines how it will behave when interacting with other chemicals. The key in determining how an atom will behave in different environments lies in the arrangement of electrons within the atom.
Which atomic particle determines the chemical behavior of an atom?
protons The number of protons inside a nucleus must equal to the number of electrons outside of the nucleus. This number determines all the chemical properties of the atom, which governs the behaviors of all matters in our world.
What determines the name of an atom?
Explanation: The identity of the element is determined by the number of protons, which are positively charged, massive nuclear particles. The number of protons in a nucleus is given by Z , the atomic number.
What determines the chemical and electrical properties of an atom quizlet?
Valence electrons are the electrons on the outmost level (orbital) of the atom and determine the chemical properties of the atom such as reactivity.
Which particles is responsible for chemical properties of matter?
The chemical properties of an element are determined by the subatomic particle known as a proton.
What subatomic particle determines the atoms chemical properties?
protons The number of protons inside a nucleus must equal to the number of electrons outside of the nucleus. This number determines all the chemical properties of the atom, which governs the behaviors of all matters in our world.
How do protons neutrons and electrons determine the properties of an atom?
The number of protons along with the neutrons will help to determine the mass number of the chemical element. The number of protons will determine the number of the electrons present. This electron will determine the chemical properties of the element.
Why do valence electrons determine chemical properties?
The number of valence electrons in atoms may cause them to be unreactive or highly reactive. For those atoms that are reactive, the number of valence electrons also determines whether they tend to give up or gain electrons in chemical reactions. Metals, which easily give up electrons, can conduct electricity.
What does chemical properties depend upon?
The correct answer is the number of electrons in the outermost shell of the element. The chemical properties of an element depend on the number and the configuration of its valence electrons.
How the protons determine the chemical properties of an atom?
The number of protons will determine the number of the electrons present. This electron will determine the chemical properties of the element. The chemical properties of an atom will depend on the number of valence electrons present. Depending on the valence electrons, the atom will form positive or negative ions.
Why do electrons determine the chemical behavior of an atom?
The electrons in the energy levels with the highest number are, on average, the farthest from the nucleus. Because differences in electrons located in the outermost level distinguish an atom from its nearest noble gas, these are the electrons responsible for the atom's chemical behavior.
What do valence electrons determine?
Valence electrons are the outer-shell electrons of an atom. Valence electrons determine the reactivity of an atom.
How do protons determine the chemical properties of an atom?
The number of protons will determine the number of the electrons present. This electron will determine the chemical properties of the element. The chemical properties of an atom will depend on the number of valence electrons present. Depending on the valence electrons, the atom will form positive or negative ions.
How does valence electrons relate to chemical properties?
Valence electrons, the electrons in the outermost or valence shell, are important as they provide insight into an element's chemical properties and are the ones gained, lost, or shared during a chemical reaction. In general, atoms are most stable and least reactive when their outermost electron shell is full.
