How are the chemical properties of an atom determined?
The chemical properties of an element are determined by the number of electrons in its atom, which in turn is determined by the number of protons.
What determines the chemical properties of an atom 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 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 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.
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.
Which property determines the chemical reactivity of an element?
The number of electrons in the outermost shell of an atom determines its reactivity.
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 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.
What depends on the chemical behavior of the atom?
the number of nucleons in its nucleus.
What do chemical properties depend on?
The chemical properties depend on the number of the electrons and the configuration of the valence electrons of that 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 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.
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.
What determines the identity of an element?
Correct answer: The identity of an element is determined by the number of protons. One cannot alter the number of protons without altering the identity of the element. By adding a proton, the atomic number increases by one and the element identity changes. Number of neutrons can be altered to create isotopes.
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.
Does the chemical properties depend upon atomic mass?
The chemical properties of an atom depend upon the atomic number. From the atomic number, we can get valence electrons that determines the chemical properties of it. Was this answer helpful?
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.
How does electron configuration determine chemical properties?
This allows us to determine which orbitals are occupied by electrons in each atom. The specific arrangement of electrons in orbitals of an atom determines many of the chemical properties of that 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.
What is the most important thing in determining the identity of an atom?
1 Answer. The proton determines the identity of an element.
Which of the following determines an atom’s ability to undergo chemical reactions?
An atom's ability to undergo chemical reactions is determined by its outermost electrons.
What contributes to the chemical properties of an element?
The chemical properties of an element are due to the distribution of electrons around the atom's nucleus, particularly the outer, or valence, electrons; it is these electrons that are involved in chemical reactions.
What determines the chemical reactivity of element answer in one sentence?
Ans: The chemical reactivity of an element is determined by the number of valence electrons in it and the shell number of the valence shell.
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.
Why do electrons determine 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.
Which of the following has influence on the chemical properties of an element?
The properties of an element are determined largely by the electrons in its outermost or valence shell. Valence electrons interact with other atoms and take part in all chemical reactions, while inner shell electrons have little influence on the properties of elements.
What are the chemical reactions are determined by?
Chemists classify chemical reactions in a number of ways: by type of product, by types of reactants, by reaction outcome, and by reaction mechanism. Often a given reaction can be placed in two or even three categories, including gas-forming and precipitation reactions.
Why do atoms undergo chemical reactions?
Atoms form chemical bonds to make their outer electron shells more stable. The type of chemical bond maximizes the stability of the atoms that form it.
What causes chemical reactivity?
Chemical reactions involve breaking chemical bonds between reactant molecules (particles) and forming new bonds between atoms in product particles (molecules). The number of atoms before and after the chemical change is the same but the number of molecules will change.
