<u>Answer:</u>
<em>Ion formed from the atom contains </em><u><em>8 positive protons and 5 negative electrons </em></u>
<em></em>
<u>Explanation:</u>
Atomic number = number of electrons = number of protons
So the atom contains 8 protons and 8 electrons
Protons are positively charged and electrons are negatively charged.
An ion with a positive charge (cation) is formed by the loss of negative electrons
An ion with a negative charge (anion) is formed by the gain of negative electrons.
The question says ion has a net charge of 3+ so it means the atom has lost 3 electrons from it.
So ion formed from the atom contains 8 positive protons and 5 negative electrons (Answer)
To find the number of neutrons we make use of the formula
Please Note: Mass number - atomic number = number of neutrons
