1
Valence electrons are
The electrons in the outermost level.
The total number of electrons in all levels.
The electrons in the innermost level.
2
A Lewis Dot diagram shows only
The total number of electrons in an atom
The number of protons
The number of valence electrons
The number of neutrons
3
The number of neutrons in a atom can be found by
Subtracting the number of electrons from the atomic number
Adding the atomic mass to the atomic number
Adding the number of protons and the number of neutrons
Subtracting the atomic number from the atomic mass
