Answer:
Magnesium has 2 valence electrons.
Explanation:
The atomic number of magnesium is 12. This means that it has 12 protons and 12 electrons. The first electron shell can hold 2 electrons, the second can hold 8, so the third will have 2 electrons. The outermost shell of the atom has two electrons. Therefore, magnesium has 2 valence electrons.

The best way is to organize and name the organisms that live in specific types of deserts.
Answer:
1. For the first reaction, there is Carbonation and rearrangement
2. For the second reaction, No Carbonation, No rearrangement.
Explanation:
See attached screenshot below
the 1st one is balanced, the 2nd isn't (the number of Mg differs from left 1 to right 2).
The third is also not balanced, 2 F left,2*3=6 on the right
