Calcium metal is an electron donor.
As a group 2A metal, calcium has two valance electrons that it tends to give away to non metals, forming the Ca 2+ cation.
Ca --> Ca2+ + 2 e-
However, often people say calcium, when they mean calcium ion. Be sure which you are asking about.
Calcium is more prone to lending electrons than borrowing them. It can lend a total of two electrons.
It donates electrons so that it can become noble.
Calcium does not "borrow" electrons. Calcium "donates" 2 electrons.
Yes it give away electrons.It gives away two
Calcium give two electrons.

Technically, any atom could have 40 electrons, but it would have a very weird charge. However, Zirconium has 40 electrons without being an ion.
Calcium has to lose 2 electrons to form noble gas configuration.
No, but some of them can donate all their valence electrons. Let us take a ridiculous example. Copper is [Ar]4s2d9. Donating 11 valence electrons would be energetically impossible. Now Vanadium is different and is [Ar]4s2d3 and so only needs to donate 5 valence electrons. This can be and is done V2O5 is a very stable compound - vanadium pentoxide.
Well the charge on the compound would be stable (0) when bonded, because the Calcium has given it's electrons to the Oxygen atom. But the charge on the calcium ion itself would be 2+
Ca has 2 electrons in its valence shell. When ionized, it transfers its 2 extra electrons to another atom in order to stabalize its outer shell. Therefore, it is losing 2 negatively charged particles and gains a charge of "2+".
Calcium has twenty electrons in each atom.
calcium loses two electrons, becoming a +2 ion
A Calcium ion with a -1 net charge would have 21 electrons. Calcium as a stable element has 20 electrons.
The neutral atom of calcium has 20 electrons; the cation Ca2+ has 18 electrons.
Under normal conditions of temperature and pressure, oxygen gains electrons. The outermost orbital in an oxygen atom has four electrons., i.e., the outermost orbit has six electrons. Hence, to reach the octet configuration, oxygen can take two more electrons. Thus, oxygen is electronegative.
Technically, any atom could have 40 electrons, but it would have a very weird charge. However, Zirconium has 40 electrons without being an ion.
Like all metals calcium will lose electrons.
Argon
It becomes a calcium cation - Ca2+
Calcium is a metal. Metals give away their electrons off to non-metals. So i would say when calcium is combining with another atom it wants to give away its electrons so it can be an ion.
Calcium has to lose 2 electrons to form noble gas configuration.
The atomic number for calcium 20 so to make it neutral it should loss 2 electrons
