What is the net electrical charge on a magnesium ion that is formed when a neutral magnesium atom loses two electrons?

As we know that fundamental charge due to an electron is given by

so here we will say that charge on an atom due to loss of electron is termed as positive charge while due to gain of electron it is negative charge

Here when magnesium loses two electrons it will become positively charged

And total charge on it is given as

now we know that

N = 2 electrons

so charge on it is given as

it was given as a lesson and guide for prayer.
