A) sodium (11)
B) magnesium (12)
C) chlorine (17)
D) neon (10)
E) argon (18)
Second Energy Level
The energy level beyond the first in an atom where electrons can reside, typically holding up to eight electrons.
Electrons
Subatomic particles with a negative charge, orbiting the nucleus of an atom and involved in chemical bonds and electrical current.
