Which of the following best describes the significance of valence electrons in an atom?
A
They determine the chemical reactivity and bonding behavior of the element.
B
They are responsible for the atomic mass of the element.
C
They determine the number of neutrons in the atom.
D
They are found only in the nucleus of the atom.
Verified step by step guidance1
Understand that valence electrons are the electrons located in the outermost shell (energy level) of an atom.
Recognize that these valence electrons are the ones involved in forming chemical bonds with other atoms, which directly affects how an element reacts chemically.
Recall that atomic mass is primarily determined by protons and neutrons in the nucleus, not by electrons, so valence electrons do not influence atomic mass.
Note that the number of neutrons is independent of the electrons and is related to isotopes, so valence electrons do not determine neutron count.
Remember that electrons, including valence electrons, are found in electron clouds or shells around the nucleus, not inside the nucleus itself.
