Answer :
The ion that has 10 electrons and lost 3 electrons is aluminum (Al³⁺).
An atom or molecule with a net electrical charge is known as an "ion." Conventionally, the electron charge is negative. This charge is equal to and opposite to the proton charge, which is positive.
Given that the ion has approximately 10 + 3 = 13 electrons, this is the number of electrons, which is equal to the number of protons. The number of protons is the element's atomic number.
Looking through the periodic table, find the element that has an atomic number of 13. We have found it to be aluminum (Al). Its ion form is written as Al³⁺. To form an ion, aluminum loses three electrons. As a result, it carries a 3+ charge.
