Question

Subscripts in the chemical formula $A_3{B}_8$ denote 3 atoms of A are mixed with 8 atoms of B.

• A. is true and B is false.
• B. A is false and B is true.

Answer 1

The correct option is B

A is false and B is true.

The formula $A_3{B}_8$ denotes that 3 atoms of A have chemically combined with 8 atoms of B to give one molecule of $A_3{B}_8$. The subscripts represent the number of atoms of the participating elements. The word 'mixed' is incorrect here, because it refers to physical mixing, whereas the formation of a molecule involves the chemical combination of two or more atoms.
