unpaired
valence
paired
core electrons

most monoatomic (one single atom) anions from when a neutral nonmetal atom gains sufficient electrons to completely fill ____________ and attain an electron configuration equivalent to the next noble gas.
the outer p and d orbitals
the outer s and p orbitals
the outer p and f orbitals
the outer s and d orbitals

Explanation:

1. Main - group metals form cations by losing valence electrons to achieve a stable electron - configuration similar to a noble gas.
2. Non - metal atoms gain electrons to fill their outer s and p orbitals to attain a noble - gas electron configuration and form monoatomic anions.

Answer:

1. B. valence
2. B. the outer s and p orbitals
