What elements form an ion with a charge of 2?

Answer 1

All the elements in Group 2A (Mg, Ca, etc.). A charge of 2+ is acquired by these metals in order for a more stable state to be achieved.

Answer 2

Elements in Group 2 of the Periodic Table form ions with a charge of 2. This group includes elements such as calcium, magnesium, and barium. When these elements lose two electrons, they form ions with a +2 charge.

Answer 3

Elements having 2 valence electrons form ion with a charge of 2.

and the elements which need two electrons to complete its octet form ion with -2 charge.

Answer 4

Oxygen forms oxide, also sulfur, selenium and tellurium form 2 minus charge ions

Answer 5

Calcium
