Explanation:
Detailed explanation-1: -Answer and Explanation: The answer is a. gain 1. In order to achieve an octet of electrons, the atom may lose 7 electrons or gain one electrons such that it will have an octet of electrons similar to a noble gas.
Detailed explanation-2: -1 only because it is a group 1 element so it has only 1 electron in its outer most shell and when it loses that electron it becomes stable and gets a charge of +1 on it.
Detailed explanation-3: -Potassium is an exception to the octet rule and can hold up to 12 electrons in its valence electron energy level in a compound.
Detailed explanation-4: -Potassium has one valence electron. This means that there is one electron in its outermost shell (4th shell).
