Elements were grouped on their properties and behaviors, so hydrogen resides with the alkali metals in group 1 (1A) because it has only 1 valence electron, like the metals in that group.
N=2 (always first number), l=1 (corresponds to p), ml=(-1 to 1)
If the earth's orbit is far from the sun, then, its rate will be slower than when it is closer to the Sun. When gravitational field lines get closer together,
the magnetic force is strong. We
know that the heavier the body is, the stronger its gravitational pull.<span>

Yes <u><em>true</em></u>
I can't come up with a good explanation.
