The calcium atom will transfer its two valence electrons, one to each of two iodine atoms, to form the compound calcium iodide, CaI2.
The formula CaF as written in the question shows two atoms; however this formula does not represent any actual compound. The compound between calcium and fluorine has the formula CaF2, because calcium forms divalent cations and fluorine forms monovalent anions. Therefore, the formula unit for calcium fluoride contains 3 atoms.
149 g of calcium contain 22,39.10e23 atoms.
When calculating calcium you must first see how many moles are there. There are 2.6Ã?10^24 atoms in 173 grams of calcium.
The answer is 18,061.1023 atoms.

Calcium chlorate has the formula Ca(ClO3)2. Therefore, there are two chlorine atoms in each formula unit.

there are 20 atoms in calcium
There are three atoms of oxygen per calcium carbonate molecule. name: chalk IUPAC name: calcium carbonate compound formula: CCaO3 formula: CaCO3 (This information was obtained from http://www.wolframalpha.com)
Three oxygen atoms in each nitrate ion multiplied by two nitrate ions results in 6 total oxygen atoms.
There are 7 atoms: 1 calcium, 2 carbon, and 4 oxygen.
Calcium sulfide (CaS) has two atoms.
There are three atoms in CaCl2 (calcium chloride) - one calcium atom and two chlorine atoms. It might be argued that there are ions inside the molecule instead of atoms. In that case there is one calcium ion and two chlorine ions.
149 g of calcium contain 22,39.10e23 atoms.
