Question

match each element to the correct description of its usual behavior in a chemical reaction. silicon (si), argon (ar), oxygen (o), sodium (na). does not gain or lose electrons, could lose or gain electrons, will gain electrons, will lose electrons

Explanation:

Sodium (Na) is a group 1 metal with 1 valence electron, so it loses electrons. Oxygen (O) is a group 16 nonmetal with 6 valence electrons, so it gains electrons. Argon (Ar) is a noble gas with a full octet, so it does not gain/lose electrons. Silicon (Si) is a group 14 metalloid with 4 valence electrons, so it could lose or gain electrons.

Answer:

Sodium (Na) - Will lose electrons, Oxygen (O) - Will gain electrons, Argon (Ar) - Does not gain or lose electrons, Silicon (Si) - Could lose or gain electrons
