If calcium lost two electrons it would have the same number of electrons as?

If calcium lost two electrons, it would have the same number of electrons as argon. Calcium has 20 electrons in its neutral state, and losing two electrons would leave it with 18 electrons, which is the same as argon.


How many electrons are in a calcium atom and in a calcium ion?

A calcium atom has 20 electrons, as it has 20 protons to maintain a neutral charge. A calcium ion, specifically Ca2+, has lost two electrons, so it has 18 electrons.


What is gained in a chemical reaction?

Electrons are the ones gained or lost in a chemical reaction. Electrons are gained in oxidation and lost through the chemical reaction known as reduction.


How many electrons are gain or lost to form ions for calcium?

A calcium atom loses 2 electrons to form a Ca2+ ion. This is because calcium has 20 electrons in its neutral state, and it becomes more stable by losing these 2 outer electrons to achieve a full valence shell.
