A magnesium atom is a neutral atom where the number of protons and electrons are the same. A magnesium ion has a positve 2 charge since it will lose two of its electrons when it undergoes ionic bonding. Since it's the same element it will still have the same amount of 12 protons. For isotopes of magnesium, they will have differing amounts of neutrons and thus a difference in the mass number since neutrons have a mass of about 1
2 Ca₅(PO₄)₃F + 7 H₂SO₄ → 3 Ca(H₂PO₄)₂ + 7 CaSO₄ + 2 HF
Explanation:
To balance the chemical reaction the number and type of atoms entering the reaction have to be equal to the type and atoms leaving the reaction.
In our case we have:
10 Ca entering the reaction and 10 Ca leaving the reaction
6 PO₄ groups entering the reaction and 6 PO₄ groups leaving the reaction
2 F entering the reaction and 2 F leaving the reaction
7 SO₄ groups entering the reaction and 7 SO₄ groups leaving the reaction
14 H entering the reaction and 14 H leaving the reaction

science of love
,EXPLANATION:
The initial happy feelings of being in love is stimulated by 3 chemicals in the brain: noradrenaline that stimulates adrenaline production causing that racing heart and sweaty palms; dopamine, the feel-good chemical; and phenylethylamine that is released when we're near our crush, giving us butterflies in our tummies.
