What must happen to an atom of magnesium in order to become a magnesium ion mg+2?

Magnesium must lose two electrons to become

Explanation: Magnesium(Mg) ia a metal with atomic number of 12 and atomic mass of 24.

Atomic no = no of electrons = no of protons

Atomic Mass = no. of protons + no. of neutrons

Thus Magnesium in neutral form has got 12 electrons and 12 protons. In order to acquire a charge of +2 it must loose two electrons. Now the no of protons will be greater than no of electrons and thus the atom will acquire positive charge.

8

explanation:

each principal energy level above the first contains one s orbital and three p orbitals. a set of three p orbitals, called the p sublevel, can hold a maximum of six electrons. therefore, the second level can contain a maximum of eight electrons - that is, two in the s orbital and 6 in the three p orbitals.

mark brainliest and have a great day!

the answer is 1260

you spend 7 hours in school for 1 school day with 5 school days in 1 school week with 36 school weeks in a school year.

7*5*36= 1260 it's all about multiplying
