B. The atom is stable and will not react with other atoms
C. The atom will always lose electrons to fill its valence shell
D. The atom will always gain electrons to fill its valence shell

Answer 1

Answer:It’s A!

Step-by-step explanation:

Hope that helps

Answer 2

Full valence shell is best describe by :

Option A that is the atom may gain , lose or share electrons to fill its valence shell.

Valence shell have stable electronic confrigration . To achieve the stability they can gain or lose the electron .

Examples: helium , neon and argon belongs to group 18 they have stable electronic confrigration.
