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.
Deca stands for 10. So there are ten chlorine atoms is decachloride.
It tells what elements are present in a molecule and how many atoms of each element are present.
The formula of a compound is written using the symbols of the elements present in the compound and subscript numbers to represent the ratio of each element in the compound. The subscript numbers indicate how many atoms of each element are present in a molecule of the compound.
A molecular formula.
K= 2 C= 1 O=3 K2CO3= 6 atoms
The chemical formula is MoPO4; the molecule contain four oxygen atoms.
The atomicity of a compound indicates how many atoms are present in a single molecule of the compound. In the case of calcium hydroxide (Ca(OH)2), the atomicity is 4 (1 calcium atom + 2 oxygen atoms + 2 hydrogen atoms). This calculation considers the total number of different atoms present in the molecule.
For every 15 X atoms in the compound X3Y, there would be 3 Y atoms. This is because the ratio of X to Y in the formula is 3:1, so for every 3 X atoms, there is 1 Y atom.
