The formula is Ca(ClO3)2, so the total number of atoms in the compound is 9.

five One calcium atom, one carbon atom, and three oxygen atoms.
The formula unit for calcium nitride is Ca3N2. That would be 3 atoms of calcium and 2 atoms of nitrogen, for a total of 5 atoms in a formula unit.
Calcium fluoride or CaF2 is comprised of two elements: calcium (Ca) and fluoride (F). One molecule of CaF2 thus contains two atoms of F and one of Ca for a total of three.
Calcium ions have a charge of +2 and nitrate ions (NO3) have a charge of -1. Because compounds are neutral, you need two nitrate ions to cancel out one calcium ion. Thus the formula for calcium nitrate is Ca(NO3)2. Nitrate has four atoms (one nitrogen and three oxygen). But there are two nitrate ions, so that makes eight atoms. Then you add on the one calcium atom for a total of nineatoms.
The total number of calcium atoms in 80,0 grams of calcium is 12,044 280.10e23.
The total number of atoms in 3.5 moles of calcium is 21,0774929995.10e23.
This number is 50 atoms.

Ca is calcium, one atom.
five One calcium atom, one carbon atom, and three oxygen atoms.
12.7 moles calcium (6.022 X 10^23/1 mole Ca) 7.65 X 10^24 atoms of calcium in 12.7 moles.
The formula unit for calcium nitride is Ca3N2. That would be 3 atoms of calcium and 2 atoms of nitrogen, for a total of 5 atoms in a formula unit.
In Ca(ClO3)2 there are one calcium atom, two chlorine atom and six oxygen atom. So total of nine atoms
Calcium fluoride or CaF2 is comprised of two elements: calcium (Ca) and fluoride (F). One molecule of CaF2 thus contains two atoms of F and one of Ca for a total of three.

Thus the formula for calcium nitrate is Ca(NO3)2. Nitrate has four atoms (one nitrogen and three oxygen). But there are two nitrate ions, so that makes eight atoms. Then you add on the one calcium atom for a total of nineatoms.
Depends on what you mean by number of electrons. Calcium has 20 electrons and oxygen has 8 electrons for a total of 28 electrons. But if you mean how many VALENCE electrons, then the calcium has 2 and the O has 6 for a total of 8 valence electrons.
