What is the total number of electrons in a Mg2 positive ion?

Answer 1

The Magnesium atom will lose 2 of its electrons to become a Magnesium ion with 10 electrons. (Mg2+) How many electrons does a magnesium ion have?

How many electrons does a fluoride ion have?

How many electrons does a fluoride ion have?

Answer 2

A Mg2+ ion has lost 2 electrons from a neutral magnesium atom. Therefore, the Mg2+ ion has 10 electrons in total.

Answer 3

The atomic number of magnesium is 12.

Answer 4

If it's charge is +2 then that means it has 2 less electrons than protons. A Mg atom has 12 electrons and a Mg ion has 10 electrons.

Answer 5

magnesium has got 12 electrons and 12 protons.

Answer 6

There are 2 electrons in Mg's first energy level.

Answer 7

The first energy level of any element can contain only 2 electrons (no more). These are the 1s2 electrons. So, the answer is that Mg has 2 electrons in the first energy level.

Answer 8

Magnesium has two electrons in its first energy level.

Answer 9

The number of electrons is 10 in the cation.

Answer 10

Mg2+ has 10 electrons (K,L,M = 2,8,0)
