what ion is formed when an atom of magnesium (mg) loses two electrons? mg–1 mg–2 mg+1 mg+2
Hi Game, I have a question. What ion is formed when an atom of magnesium (Mg) loses two electrons?
Hello, great question! When a magnesium (Mg) atom loses two electrons, it forms a Mg+2 ion. This is because it has lost two negative charges (the electrons), making it overall positively charged.
So, is that why it's called a positive ion?
Absolutely! Ions that have lost electrons and have become positively charged are called cations. So, Mg+2 is a cation.
Does this happen frequently for other elements as well?
Yes, indeed. Many elements lose or gain electrons to achieve a full outer electron shell, which is a more stable state. This process of electron loss or gain results in the formation of ions.
I see, it's much clearer now. Thank you!
