How many valence electrons does an atom have if the atom has an atomic number of
10?
Correct Answer: 8 valence e- because it ends with 2s2 2p6
C
How many valence electrons will an atom have if the atom is located in Group VIA of
the periodic table?
LE
Correct Answer: VI=6
ST
An atom located in which of the following groups on the periodic table of elements will
most likely gain electrons from another atom in a chemical reaction?
BE
Correct Answer: The higher the valence electrons, the most likely it'll want to gain-
so it can be full.
