Answer

Answer:

B. lost one electron

Brief Explanation:

Atoms become positively - charged ions (cations) by losing electrons. Potassium (K) has an atomic number of 19. In its neutral state, it has 19 protons and 19 electrons. The $K^{+}$ ion has a + 1 charge, which means it has lost one electron, resulting in 19 protons and 18 electrons. Protons are not lost or gained in normal chemical reactions that form ions; they are located in the nucleus and remain constant for a given element.
