In an atom, where are the electrons that are primarily involved in chemical bonding located?
A
In the outermost (valence) shell
B
Distributed equally among all shells
C
In the nucleus
D
In the innermost (core) shell
Verified step by step guidance1
Understand that electrons in an atom are arranged in energy levels or shells around the nucleus.
Recognize that the electrons in the innermost shells (core electrons) are tightly bound to the nucleus and generally do not participate in chemical bonding.
Identify that the outermost shell of an atom is called the valence shell, which contains the valence electrons.
Know that valence electrons are the ones primarily involved in chemical bonding because they can be gained, lost, or shared to form bonds.
Conclude that the electrons involved in chemical bonding are located in the outermost (valence) shell of the atom.
