Question

which best describes the potassium ion that forms? it is a negative ion that has one less valence electron than a neutral potassium atom. it is a negative ion that has one more valence electron than a neutral potassium atom. it is a positive ion that has one less valence electron than a neutral potassium atom. it is a positive ion that has one more valence electron than a neutral potassium atom.

Explanation:

Potassium (K) is in Group 1 of the periodic table and has 1 valence - electron. It loses this 1 valence - electron to form a stable ion. When an atom loses an electron, it forms a positive ion (cation).

Answer:

It is a positive ion that has one less valence electron than a neutral potassium atom.
