An atom of neon has 8 valence electrons. What will an atom of neon MOST likely do to be stable?
|
|
Gain 1 electron
|
|
|
Lose 2 electrons
|
|
|
Lose 8 electrons
|
|
|
Neither gain nor lose any valence electrons
|
Explanation:
Detailed explanation-1: -Neon, with its configuration ending in 2s22p6, has eight valence electrons. The alkali metal sodium (atomic number 11) has one more electron than the neon atom.
Detailed explanation-2: -Because the second energy level (2s22p6) has eight electrons Neon has an octet and has a full outer shell. It is therefore a Nobel Gas.
