Multiple Choice
Which of the following is the most important factor in determining how an atom will bond?
A
The number of valence electrons
B
The number of neutrons
C
The total number of protons and electrons
D
The atomic mass
Verified step by step guidance
1
Understand that chemical bonding primarily involves the interaction of electrons between atoms, not protons or neutrons.
Recall that valence electrons are the electrons in the outermost shell of an atom and are responsible for forming bonds with other atoms.
Recognize that the number of neutrons affects the atomic mass and isotope identity but does not directly influence bonding behavior.
Note that the total number of protons and electrons determines the overall charge and identity of the atom but bonding depends on how electrons are shared or transferred.
Conclude that the most important factor in determining how an atom will bond is the number of valence electrons, as these electrons participate in bond formation.
