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 else can I help you with?
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.
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.
What two atoms have 20 electrons combined?
Two atoms that have a total of 20 electrons combined could be calcium (Ca) and potassium (K), as calcium has 20 electrons and potassium has 19 electrons. Alternatively, you could have two atoms of calcium, which would also sum up to 20 electrons. Another combination could be a calcium atom (20 electrons) and an oxygen atom (8 electrons) if we consider a different arrangement, but that would exceed the total.
How many electrons would the element calcium need to be electrically neutral?
Calcium is an element with an atomic number of 20, which means it has 20 protons in its nucleus. To be electrically neutral, an atom must have an equal number of electrons to protons. Therefore, calcium would need 20 electrons to be electrically neutral.
How many electrons are loss for calcium to gain a full outer shell?
Calcium has two electrons in its outermost shell (the 4s subshell). To achieve a full outer shell, which would correspond to the stable electron configuration of neon, calcium must lose these two electrons. Therefore, calcium loses two electrons to gain a full outer shell.
What type of chemical bond would calcium and chlorine together?
Calcium and chlorine would form an ionic bond when they combine to create calcium chloride. Calcium, being a metal, will donate electrons to chlorine, a nonmetal, resulting in the transfer of electrons and the formation of an ionic bond.
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.
What scientific element has 20 electrons?
Calcium has twenty electrons in each atom.
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.
Would calcium gain or lose electrons?
calcium loses two electrons, becoming a +2 ion
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.
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 does calcium1- have?
A Calcium ion with a -1 net charge would have 21 electrons. Calcium as a stable element has 20 electrons.
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.
What two atoms have 20 electrons combined?
Two atoms that have a total of 20 electrons combined could be calcium (Ca) and potassium (K), as calcium has 20 electrons and potassium has 19 electrons. Alternatively, you could have two atoms of calcium, which would also sum up to 20 electrons.

How many electrons are present in 40Ca2?
A calcium ion with a 2+ charge (Ca2+) has lost two electrons. A neutral calcium atom (Ca) has 20 electrons, so Ca2+ would have 18 electrons.
How many electrons would you need to make calcium neutral?
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.
