Answer :
To find the charge of an ion, we need to consider the number of protons and electrons it has. Protons are positively charged, while electrons are negatively charged. The overall charge of the ion is determined by the difference between the number of protons and the number of electrons.
Here, we have a lead ion with:
- 82 protons
- 80 electrons
To calculate the charge of the ion, subtract the number of electrons from the number of protons:
[tex]\[ \text{Ion charge} = \text{Number of protons} - \text{Number of electrons} \][/tex]
Substituting the given values:
[tex]\[ \text{Ion charge} = 82 - 80 \][/tex]
[tex]\[ \text{Ion charge} = 2 \][/tex]
Thus, the charge of the ion is +2. Therefore, the correct equation to find the charge of the ion is:
(B) ion charge [tex]\( = 82 - 80 \)[/tex]
