Depending on the formula !
Two atoms in PbO2, three atoms in Al2O3, etc.
There are 5 atoms represented in the formula CaCO3: 1 calcium (Ca) atom, 1 carbon (C) atom, and 3 oxygen (O) atoms.
There are 6 hydrogen atoms, 3 phosphorus atoms, and 4 oxygen atoms in the formula H3PO4.

To determine the total number of atoms in the chemical formula Sq2R3, you need to consider the subscripts. The formula indicates there are 2 atoms of element Sq and 3 atoms of element R. Therefore, the total number of atoms is 2 (from Sq) + 3 (from R) = 5 atoms.
The subscript number after the element symbol, such as the 2 in H2O, tells how many atoms in each molecule. In the example, the 2 refers to H (hydrogen). If there is no number present, then 1 is implied. So H2O has 2 hydrogen and 1 oxygen.
Depending on the formula of the chemical compound containing aluminium.
There are 5 atoms represented in the formula CaCO3: 1 calcium (Ca) atom, 1 carbon (C) atom, and 3 oxygen (O) atoms.
A chemical formula is the representation of a molecule of a chemical compound; all the atoms from the molecule of this compound need to be represented in the formula.
Multiply the coefficient in front of the formula times the subscript for each element. This gives 36 carbon atoms, 72 hydrogen atoms, and 36 oxygen atoms.
The chemical formula shows you this. The subscripted number next to each element shows how many atoms are present in a molecule or formula unit. If no number is shown, then only one atom of that element is present.
There are 6 hydrogen atoms, 3 phosphorus atoms, and 4 oxygen atoms in the formula H3PO4.
The formula CaCO3 represents 5 atoms: 1 calcium atom, 1 carbon atom, and 3 oxygen atoms.

Each atom has its own elemental 'symbol' or 'formula', there are more than 92 elements: from number 1. Hydrogen (H) to number 92. Uranium (U). Examples: O for oxygen, C for carbon, N for nitrogen atoms.
You can determine the number of atoms of each element in a compound by using the chemical formula of the compound. The subscripts in the formula indicate the number of atoms of each element. For example, in H2O (water), there are 2 hydrogen atoms and 1 oxygen atom.
