6. write the complete chemical symbol for the ion with 82 protons and 80 electrons.
Answer
Answer:
$\ce{Pb^{2+}}$
Explanation:
Step1: Identify the element
The number of protons determines the element. With 82 protons, the element is lead, symbol $\ce{Pb}$.
Step2: Determine the charge
The ion has 82 protons and 80 electrons. Protons are positively - charged and electrons are negatively - charged. The charge of the ion is calculated as $82-(80)= + 2$. So the ion is $\ce{Pb^{2+}}$.
