Answer:
Subscript
Explanation:
For example [tex]Ca_1 Cl_2[/tex] shows 1 atom of Ca and 2 atoms of Cl
Another example
[tex]3Ca_3 (P_1 O_4 )_2[/tex]
we multiply
Coefficient × subscript × number outside the bracket.......... to find the number of atoms
(Please note: 3 is the coefficient, and if there is no number given then 1 will be the coefficient )
So,
[tex]3 \times 3 = 9[/tex] , Ca atoms
[tex]3 \times 1 \times 2 = 6[/tex] , P atoms
[tex]3 \times 4 \times 2 =24[/tex], O atoms are present.
