Answer:
The 2 in the formula means that, there are 2 phosphate anions that forms the salt.
Explanation:
Magnesium phosphate is a ionic salt.
The formula indicates that 3 moles of Mg and 2 moles of anion phosphate are contained in 1 mol of compound.
3Mg²⁺ + 2PO₄⁻³ → Mg₃(PO₄)₂
The phosphate anion comes from phosphoric acid and it is generated when the acid loses the 3 protons.
H₃PO₄ → 3H⁺ + PO₄⁻³
Phosphate has a negative charge of -3, so when it bond to magnesium, which has a charge of +2, there must be 3 magnesium and 2 phosphate to make a global charge +6 -6 in the ions

Answer:
Cesium has one valence electron that can be removed from itself resulting to its stable monatomic ion of Cs+ .
Explanation:
Is there a picture? If not then it’s probably precipitate
Answer:
Na: 1s2 2s2 2p6 3s1
Na+: 1s2 2s2 2p6
Na+ electronic configuration resemble that of Neon( 1s2 2s2 2p6)
In general, the electronic configuration of alkali metals ions resemble that of the group zero (noble gas)
