Question

1 why does the element sodium (na) readily form compounds? select two correct answers. sodium (na) is found in the most reactive period. group 1 elements are the least reactive and form compounds easily. losing one electron creates a stable electron arrangement. gaining one electron creates a stable electron arrangement. sodium (na) has just one valence electron which is easily lost.

Explanation:

Sodium is in Group 1 of the periodic table. It has 1 valence electron. Losing this one electron gives it a stable electron - configuration like that of a noble gas. Group 1 elements are highly reactive, not the least reactive. Sodium is not in the most reactive period. Gaining an electron is not how sodium achieves stability.

Answer:

C. Losing one electron creates a stable electron arrangement.
E. Sodium (Na) has just one valence electron which is easily lost.
