Answer: Number of protons and number of valance electrons.
Explanation:
There are three factors which determine metallic bond strength. greater the no of protons, greater will be attraction between nucleus and valance shell electrons and stronger will be metallic bond. greater no of valance electron, greater will be attractions between nucleus and electrons and stronger will be bond.

Avogardo's number is a constant, named after the scientist Amedeo Avogadro that represents the number of molecules or atoms that are contained in the amount of substance given by one mole.<span> Na= 6.022×10</span><span>23
Mole on the other hand is </span> a chemical mass unit,defined to be 6.022 x 1023 molecules<span>, </span>atoms, or some other unit. This is the reason why t<span>he mole and Avogadro’s number are now almost synonymous with each other. </span>
Answer:
The balanced chemical equation for the combustion of propane is: C3H8(g)+5O2(g)→3CO2(g)+4H2O(g).
