Explanation:

Potassium (K) is in Group 1 of the periodic table. Elements in Group 1 have 1 valence electron. To achieve a stable electron configuration (similar to the noble gases), potassium atoms tend to lose this 1 valence electron. When an atom loses an electron, it forms a positively - charged ion. The chemical symbol for a potassium ion after losing one electron is \(K^{+}\).

Answer:

loses one electron, forming \(K^{+}\)
