State the number of atoms present in each of the following chemical species.
a) `CO_(3)^(2-)`
`PO_(4)^(3-)`
c) `P_(2)O_(5)`
d) CO

Text Solution

Verified by Experts

a) Number of atoms in `CO_(3)^(2-)` = number of C-atoms + number of O atoms =1+3=4
b) Number of atoms in `PO_(4)^(3-)` = number of P-atoms + number of O-atoms =1+4=5
c) Number of atoms in `P_(2)O_(5)` = number of P-atoms + number of O-atoms =`2+5=7`
d) Number of atoms in CO= number of C-atoms + number of O-atoms `=1+1=2`
