There are 20 protons in a calcium atom. You can find the number of atoms in any element by looking at the atomic number which is in the top right corner of the element's box on the Periodic Table. e.g. Ca 20 40.078

How many calcium atoms are in the compound CaNO32?
CaNO32 ??? No such molecule. This indicates that there are '32' oxygen atoms in the molecule. I think you mean ' Ca(NO3)2 ' (Calcium nitrate) . Note the use and position of the brackets. This indicates that there are two nitrate anions in the molecule. The formula ' Ca(NO3)2 ' tells us that there are ;= 1 x Ca^(2+) ; ONE calcium cation . (NOT atom). 2 x NO3^(-) ; TWO nitrate anions. Each nitrate anion has one nitrogen ATOM and three oxygen ATOMS bonded covalently. Leaving one 'spare' electron to bond ionically with the calcium cation. Since the calcium cation has a charge of '2+ ' , then we MUST have TWO nitrate anions each of charge ' - ' , in order to balance the charges. So overall you have 1 x calcium cation. 2 x nitrogen atoms 2 x 3 = 6 oxygen atoms. NB THe use of brackets to indicate multiple units is universal . NNB When an atom gains or loses electrons, to becomes a charged species, it is no longer an atom but an ION .

How many atoms does calcium hypochlorite have?
Calcium hypochlorite - Ca(ClO)2 has 5 atoms.
How many atoms are in 3CaCL2?
None!!! There is no such substance as ' CaCL2 '. There is no element with the symbol 'L'. However, if you mean ' CaCl2 . Then one molecule contains three atoms . viz: 1 x Ca (Calcium) 2 x Cl( Chlorine). The prefix '3' means three molar ratios. , or three molecules. So in three molecules of CaCl2 there will be 3 x 3 = 9 atoms.
