Group 1 has 1 valence electron

Group 2 has 2 valence electrons

Group 3 has 3 valence electrons

Thus, they all give electrons instead of taking like a noble gas does when satisfying the octet rule.

All of these groups have positive charges (i.e., +1, +2, +3).

ahrayia [7]

<span>The balloons volume as it rises increases because at higher altitude external pressure is lower, so the air molecules inside the balloons tends to expand more to attain mechanical equilibrium, where the external pressure and internal pressure are equal. Unlike when the balloon is on the ground, external pressure is great so the gas molecule cannot push the walls of the balloon so it is like underinflated.</span>

Which event would be impossible to explain by using John Dalton’s model of the atom?
Dvinal [7]
<span>Dalton's atomic theory proposed that all matter was composed of atoms, indivisible and indestructible building blocks. While all atoms of an element were identical, different elements had atoms of differing size and mass. Dalton also stated that all compounds were composed of combinations of these atoms in defined ratios. He postulated that chemical reactions resulted in the rearrangement of the reacting atom.
