Question

is an atom of element a
is an atom of element b
is an atom of element c
using this information and the model shown, what is the chemical
formula of this compound?
a a₈b₃c
b a₈bc₃
c a₃bc₈
d ab₈c₃

Explanation:

Step1: Count the number of each atom

Count the number of blue (element A) atoms: there are 8.
Count the number of orange (element B) atoms: there is 1.
Count the number of green (element C) atoms: there are 3.

Step2: Write the chemical formula

In a chemical formula, the subscript represents the number of atoms of each element. So the formula is \(A_{8}BC_{3}\).

Answer:

B. \(A_{8}BC_{3}\)
