Which factor primarily determines how many bonds an atom can form?
A
The number of valence electrons in the atom
B
The number of neutrons in the nucleus
C
The atomic mass of the element
D
The total number of electrons in the atom
Verified step by step guidance1
Understand that the number of bonds an atom can form is related to its ability to share or transfer electrons to achieve a stable electron configuration.
Recall that atoms form bonds primarily by using their valence electrons, which are the electrons in the outermost shell of the atom.
Recognize that the number of valence electrons determines how many additional electrons an atom needs to gain, lose, or share to complete its octet (or duet for hydrogen).
Note that the number of neutrons in the nucleus affects the atomic mass but does not influence bonding behavior directly.
Conclude that the primary factor determining how many bonds an atom can form is the number of valence electrons it has.
