For each compound below, count the TOTAL number of atoms.
Remember:
the subscripts tell you how many of each atom are in the compound. If there is NO subscript, it is understood to be 1
a chemical symbol will have 1 or 2 letters. The first letter is always uppercase, and the second letter will be lower case.if a polyatomic ion is in parentheses, the number outside the parentheses will distribute to all atoms inside the parentheses. For example: In the compound, Fe2(CO3)3 - There are 2 Fe atoms, 3 (3x1) C atoms, and 9 O (3 x 3) atoms.
NH4CI
a.3 total atoms.
b.2 total atoms.
c.4 total atoms.
d.10 total atoms.
e.5 total atoms.
f.13 total atoms.
g.7 total atoms.
h.6 total atoms.
The correct answer is h.6 total atoms.
In NH4Cl, there are 1 N atom, 4 H atoms, and 1 Cl atom. Adding these up gives a total of 6 atoms.
