When a potassium atom forms an ion, it loses one electron. what is the electrical charge of the potassium ion?

a.
+1

b.
+2

c.
-2

d.
-1

The correct answer is letter A. The electrical charge of the potassium ion becomes +1 after losing an electron. A potassium atom has a charge of zero so when it loses one electron, which has a negative charge, the potassium ion will have a +1 charge. If this electron is transferred back to the potassium ion, it will return to a charge of zero.

Wish i knew this to !
