calcium has 20 electrons.when it loses 2 electrons, it has 18 electrons.
Calcium typically loses 2 electrons to achieve a stable electron configuration, forming a Ca2+ cation. This allows calcium to achieve a full outer energy level of 8 electrons, similar to a noble gas configuration.
You would need 2 more electrons to make a calcium ion neutral, since calcium has 20 protons (+20 charge) and 18 electrons (-18 charge), resulting in an overall +2 charge. Adding 2 more electrons would balance out the charge to become neutral.
I believe it is 2, seeing it is a metal, and has 2 valence electrons. Correct me if I'm wrong, I don't have my periodic table with me (Calcium -> Ca?).
It has 20 protons, irrespective of its charge.
Calcium typically loses 2 electrons to form a stable ion with a 2+ charge. This is because calcium has 2 electrons in its outer shell, and it is energetically favorable for it to lose these electrons to achieve a full outer shell configuration.
The neutral atom of calcium has 20 electrons; the cation Ca2+ has 18 electrons.
Calcium loses two electrons to form the cation Ca2+.
18 electrons.
This cation has 24 electrons.
A cation is a positively charged ion, meaning it has lost electrons. In the case of a 1+ charge on a carbon cation, it would have 5 electrons (neutral Carbon has 6 electrons).

A Calcium ion with a -1 net charge would have 21 electrons. Calcium as a stable element has 20 electrons.
Calcium typically loses 2 electrons to achieve a stable electron configuration, forming a Ca2+ cation. This allows calcium to achieve a full outer energy level of 8 electrons, similar to a noble gas configuration.
You would need 2 more electrons to make a calcium ion neutral, since calcium has 20 protons (+20 charge) and 18 electrons (-18 charge), resulting in an overall +2 charge. Adding 2 more electrons would balance out the charge to become neutral.
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.
it loses two electrons when forming a compuond.
