A calcium atom tends to lose two electrons. This is because calcium has two electrons in its outermost shell (the fourth period of the Periodic Table), and it typically seeks to achieve a stable electron configuration by losing these two valence electrons. As a result, calcium commonly forms a +2 cation (Ca²⁺) in chemical reactions.
Calcium will lose two electrons to gain the noble gas configuration of Argon.

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.
Calcium is a non metal element. There are 20 electrons in a single atom.
A calcium atom will normally lose its two valence electrons, which have principal quantum number 4, to a more electronegative atom when forming a compound. When this happens, the already filled electron shell with principal quantum number 3 becomes the outer shell of the resulting calcium cation, and this cation has the electronic structure of the noble gas preceding calcium in the periodic table, neon
The neutral atom of calcium has 20 electrons; the cation Ca2+ has 18 electrons.
Calcium will lose two electrons to gain the noble gas configuration of Argon.
A calcium ion (Ca2+) loses two electrons from an atom to achieve a stable octet electron configuration. This results in a +2 charge on the calcium ion.
There are 20 electrons in a calcium atom.
Calcium has 20 electrons in the neutral atom.
Calcium oxide has 20 electrons from the calcium atom, and 8 electrons from the oxygen atom, totaling 28 electrons.
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?).
I am not sure what you mean by atoms, i think you mean electrons (part of an atom).Calcium is in Group 2 of the periodic table so this means that in order to become stable it will lose 2 electrons.
Calcium, as an element, has 20 electrons. But when becomes an ion, it loses two electrons, becoming Ca+2. Therefore, as an ion, calcium has only 18 electrons.18
