The calcium ion has 18 electrons.
The sulfate ion has 16 electrons from sulfur, 32 electrons from oxygen atoms and two from the charge.
Altogether, a (molecule) of calcium sulfate has 68 electrons.
* Calcium sulfate is not existing as molecules, 'formula unit' is a better phrase.
The formula unit (CaSO4) contain 6 atoms.

CaSO4 is the chemical formula of calcium sulfate.
No, because it has 2 substances in it - calcium and sulfate - Calcium is an element, but sulfate is a polyatomic ion. Sulfate consists of sulfur and oxygen. Therefore, calcium sulfate is a compound, that is, made of three elements.
The neutral atom of calcium has 20 electrons.
There are 2 electrons on the outermost shell of calcium.
Calcium sulfate is soluble in a solution of hydrochloric acid.
Calcium Sulfate has one calcium, because calcium is positively charged (2+) and sulfate is negatively charged (2-) and combines together 1 to 1 to form neutral calcium sulfate, or: Ca2+ + SO42- → CaSO4
SO4 2-
CaSO4 is the chemical formula of calcium sulfate.
There are 20 electrons in a calcium atom.
calcium has 20 neutrons and electrons
Calcium has 20 electrons in the neutral atom.
Calcium has two valence electrons.
Calcium has 20 electrons

My book says that calcium is paramagnetic but I cannot understand why since it doesn't have any unpaired electrons as paramagnetic materials need to have. I have the same question for magnesium too.
the % hydrate of calcium sulfate is 20.9%
Calcium sulfate is an inorganic compound.
