Question

give the ion symbol for the ion that has 82 protons and 80 electrons.

Explanation:

Step1: Identify the element

The number of protons is equal to the atomic number. An element with 82 protons has an atomic number of 82, which is lead (Pb).

Step2: Determine the charge of the ion

The number of electrons is 80, and the number of protons is 82. The charge of an ion is calculated as (number of protons - number of electrons). So, charge = \( 82 - 80 = +2 \).

Step3: Write the ion symbol

The ion symbol for lead with a +2 charge is \( \text{Pb}^{2+} \).

Answer:

\( \text{Pb}^{2+} \)
