Figure How many neutrons do carbon-12 and carbon-13 have, respectively?

Hint:

Figure Carbon-12 has six neutrons. Carbon-13 has seven neutrons.

Figure An atom may give, take, or share electrons with another atom to achieve a full valence shell, the most stable electron configuration. Looking at this figure, how many electrons do elements in group 1 need to lose in order to achieve a stable electron configuration? How many electrons do elements in groups 14 and 17 need to gain to achieve a stable configuration?

Hint:

Figure Elements in group 1 need to lose one electron to achieve a stable electron configuration. Elements in groups 14 and 17 need to gain four and one electrons, respectively, to achieve a stable configuration.
