Will the valence electrons of calcium give or take away electrons?
Calcium atom will generally lose two electrons to form Ca2+ ions. Calcium will not accept (gain) electrons.
How many neutrons are in a calcium ion?
it depends on the isotopes of calcium e.g. Calcium-40 has 20 electrons and 20 neutrons Calcium-44 has 20 electrons and 24 neutrons To find out the number of neutrons for Calcium you take the Isotope number (x) minus away the number of electrons (20) e.g. Calcium-x Calcium-x has 20 electrons and (x-20) neutrons.. OR you take the relative atomic mass (x) and subtract it with the number of electrons (20) (x-20) = neutrons
What is the bonding capacity of calcium?
Ionic bond is calcium's bond.
Why is calcium carbonate insoluable?
It is a very good question indeed! You see calcium chloride in which calcium is attached to two chlorine atoms is water soluble and vice versa sodium carbonate in which two sodium atoms are attached to one carbonate is soluble. In one to one proportion, calcium chloride molecule is insoluble. Now the answer for this question may go like this. In case of calcium chloride calcium gives one electron to each of chlorine atom. Now both chlorine atoms would have one negative charge. So both of them will repel each other and form the ions of calcium and two chlorine. Thus making them soluble. In case of sodium carbonate, two sodium atoms give electrons to carbonate. Now both sodium ions become positively charged and and would repel each other. So they would form ions along with carbonate. So sodium carbonate has become soluble. Now in case of calcium carbonate, calcium would like to give away 2 electrons but carbon becomes much electrically negative if it takes the electrons. So in this case no repelling force is there to help the metal, it surrenders and form sort of covalent bond and thus ions are not formed. So calcium carbonate is insoluble in water.
What must happen to a calcium atom for it to achieve noble gas structure?
It must give away two valence electrons.

Would calcium want to donate or accept electrons?
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.
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.
Why does a calcium atom want to lose it's outer electrons?
Atoms always want to have 8 electrons in their outer shell. Calcium only has two so its easier for it to give those away than to aquire 6 more. When these electrons are gone, that "shell" no longer exists so its got 8.
In chemical notation Ca2 plus means what?
calcium ions that has lost electrons. It will give away electrons.
Why is it harder to remove an electron from Magnesium than it is to remove an electron from Calcium?
Zinc has more electrons in its outer energy level than Calcium. Because of this, itsnucleus is more attracted to this energy level and pulls it more the nucleus in Calcium. Because of this greater attraction it is harder to remove the electron from Zinc.

OR you take the relative atomic mass (x) and subtract it with the number of electrons (20) (x-20) = neutrons

Reaction from iron nail and calcium metal?
The iron will not react unless you react it with calcium chloride. This is because Chloride is very electronegative (it has a high affinity for electrons) Both iron and calcium are not very electronegative and would like to give away their electrons. The Chloride ion accepts these electrons to get a full valent shell.

Why does potassium find it easier to react then lithium?
Lithium is in period 2 and potassium is in period 4.Since potassium is in a higher period, it has more shells for electrons to lie in and therefore the valance electrons (electrons in the outer shell) are further away from the positively charged nucleus. Because of the weaker electrostatic forces between the electrons and nucleus, it is easier for the electrons to be given away and hence why it is more reactive than lithium.
