Group IA are metals and all react vigorously because they have 1 valence electron in their outer most shell and the reactivity increases as you go down the group. Group VIIIA are non reactive because of their complete valence shell.
Total mass, in grams, of all the particles in one mole of the substance
Explanation:
- Molar mass is defined as the ratio of the given mass of the substance to the amount of the given substance in moles.
The formula is, Molar mass =
- By definition, these are mass in grams of all the particles in one mole of the substance. The unit of molar mass is g/ mol
- The molar mass of the element is what we see in the periodic table. The periodic table is constructed according to the atomic number of each elements and there represented the atomic mass, which is the molar mass of the elements.
The answer is Molecule. After a pair of shared electrons orbit around the nuclei of both atoms
