Question

fill in the missing words
a main group atom is the most stable when its blank shell is full. main group elements except for noble gases have an blank valence shell and can only reach the configuration of a noble gas if they lose, gain or blank electrons. atoms of metals always blank electrons when forming monoatomic ions.

Explanation:

Atoms are most stable with a full valence shell. Main - group non - noble gases have an incomplete valence shell and achieve noble - gas configuration by losing, gaining, or sharing electrons. Metals lose electrons to form cations.

Answer:

1. valence
2. incomplete
3. share
4. lose
