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.

What is the symbol for the atom that has 40 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.
How many electrons would calcium have to give up to achieve a noble-gas configuration?
Calcium has to lose 2 electrons to form noble gas configuration.
Can transition metals donate all of their electrons?
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.
What is the electric charge on the ion in the compound calcium oxide?
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+
When calcium forms an ion what is its charge?
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+".
What scientific element has 20 electrons?
Calcium has twenty electrons in each atom.
Would calcium gain or lose electrons?
calcium loses two electrons, becoming a +2 ion
How many electrons does calcium1- have?
A Calcium ion with a -1 net charge would have 21 electrons. Calcium as a stable element has 20 electrons.
If calcium is most happy with a charge of 2 how many electrons would it have?
The neutral atom of calcium has 20 electrons; the cation Ca2+ has 18 electrons.
Can oxygen accept and donate 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.
What is the symbol for the atom that has 40 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.
Would you expect calcium to gain or lose electrons in a chemical reactions?
Like all metals calcium will lose electrons.
If calcium lost two electrons it would have the same number of electrons as?
Argon
What would happen if calcium atom loses 2 electrons?
It becomes a calcium cation - Ca2+
Does calcium want to keep all of its electrons?
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.
How many electrons would calcium have to give up to achieve a noble-gas configuration?
Calcium has to lose 2 electrons to form noble gas configuration.
How many electrons would you need to make calcium neutral?
The atomic number for calcium 20 so to make it neutral it should loss 2 electrons
