Which compound
This compound is not known.
It varies with the compound.
The number of atoms in a covalent compound depends on the specific compound. Covalent compounds are formed when atoms share electrons, so the number of atoms involved in a covalent compound will be determined by the elements present and the chemical formula of the compound.
The compound is aluminum chloride (AlCl3). In this compound, there are three aluminum atoms and nine chlorine atoms (3 times as many as aluminum atoms).
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 .
A compound containing potassium and oxygen atoms would have a formula of K2O, and would be named potassium oxide. This is a binary ionic compound.
