when a potassium (k) ion is formed, what is its charge and why?\na potassium ion will form a 1− charge because it will gain one electron to achieve a full valence level.\na potassium ion will form a 1+ charge because it will gain one electron to achieve a full valence level.\na potassium ion will form a 1+ charge because it will lose one electron to achieve a full valence level.\na potassium ion will form a 1− charge because it will lose one electron to achieve a full valence level.

Answer

Brief Explanations:

Potassium is in Group 1 of the periodic table. It has 1 valence - electron. To achieve a stable full - valence level (octet rule for most elements), it loses this 1 electron. When an atom loses an electron, it forms a positively charged ion. So, a potassium ion has a 1+ charge.

Answer:

C. A potassium ion will form a 1+ charge because it will lose one electron to achieve a full valence level.
