What determines chemical behaviour of an atom?
The chemical behavior of atoms is determined by the number and the configuration of the electrons in the atom. Why should one bother to discuss the nucleus? The number of protons in the nucleus determines the number of electrons in the atom. Most atoms in the world around us are electrically neutral.
What determines the chemical behavior of an atom quizlet?
The chemical behavior of an atom is determined by the distribution of electrons in electron shells.
How do electrons determine the chemical behavior of an atom?
Electrons located in the outermost shell of the electron cloud are called “valence electrons” and have the highest energy. 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.
Which subatomic particle determines the behavior of an atom?
electrons 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 subatomic particle determines the identity of an atom quizlet?
Which subatomic particle determines the identity of an element? Protons.
What particle determines 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.
Which subatomic particle determines the chemical behavior 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 subatomic particle determines an atoms identity?
Protons – Protons are particles that are positively charged and are also located in the nucleus. Protons, including neutrons, give the atom mass but are not involved in chemical reactions. The number of protons that an atom has is called the atomic number and determines the identity of the atom.
What particle determines the reactivity of an atom?
electrons The number of electrons in the outermost shell of an atom determines its reactivity.
Why do protons determine the identity of an atom?
Proton is one of the subatomic particles which has a positive charge. The number of protons present will give the atomic number of the chemical element. Every element will have a unique atomic number. Thus, we can say that protons will determine the identity of an element.
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 determines an atom’s chemical bonding properties?
The number of electrons in each element's electron shells, particularly the outermost valence shell, is the primary factor determining its chemical bonding behavior.
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 do the neutrons determine?
The number of neutrons influences the element's mass; that is how isotopes of the same element differ.
How does an atom react chemically depends?
How an atom reacts chemically depends on how willing it is to share electrons with others.
What determines the reactivity of an element quizlet?
In the periodic table, the number of valence electrons in each element decreases from left to right across each period. The reactivity of a metal depends on how easily it loses its valence electrons.
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.
What does the electron determine?
The number of electrons in the outermost shell of a particular atom determines its reactivity, or tendency to form chemical bonds with other atoms. This outermost shell is known as the valence shell, and the electrons found in it are called valence electrons.
What part of the atom most determines the chemical properties of the atom?
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 is the most important factor that determines the chemical properties of an atom?
Statement I: The most important factor in determining the chemical properties of an element is the number of electrons in the outermost shell.
Which factor is most important in determining the chemical reactivity of an atom?
The number of electrons in the outermost shell of a particular atom determines its reactivity, or tendency to form chemical bonds with other atoms. This outermost shell is known as the valence shell, and the electrons found in it are called valence electrons.
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.
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 property determines the chemical reactivity of an atom?
The number of electrons in the outermost shell of an atom determines its reactivity.
What determines the chemical element?
The atomic number of an element is equal to the number of protons in each atom, and defines the element.
How do you determine chemical reactivity?
The chemical reactivity of a molecule is determined principally by its electron distribution.
What part of the atom is most responsible for the chemical behavior properties?
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. Answer 2: The nucleus is in the center of the atom, and it has protons and neutrons.
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.
What determines the chemical properties of elements?
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.
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.
