Answer 1

An ion with a 3+ charge and 8 protons has 5 electrons, as calculated by subtracting the positive charge from the number of protons.

Step-by-step explanation:

If an ion has a net charge of 3+ and it contains 8 protons, we can determine the number of electrons it has using the formula:

Atomic charge = number of protons - number of electrons.

In this case, the ion has a charge of +3. Therefore, it has 3 more protons than electrons. To find the number of electrons, we can rearrange the formula to solve for the number of electrons:

number of electrons = number of protons - atomic charge

number of electrons = 8 - 3

number of electrons = 5

So, the ion has 5 electrons.

Answer 2

An ion with a net charge of 3+ and 8 protons has 5 electrons.

Step-by-step explanation:

An ion with a net charge of 3+ means it has three more protons than electrons. Since the ion has 8 protons, we subtract 3 from 8 to get the number of electrons. Therefore, the ion has 5 electrons.
