For number one the answer is Iodine because it is in the same group as fluorine. For number two the answer is Germanium for the same reason. For number three the answer is Aluminum for the same reason.

Given that the electromagnetic force is far stronger than gravity on a per-particle basis, why doesn't the electromagnetic force
Kaylis [27]

Explanation:

The electro magnetic force is given by

F = \frac{k.q_{1}.q_{2}}{r^{2}}

where q_{1} and q_{2} are charged particles

           k =Coulombs constant

          r = distance between two charges

And gravitational force is given by

F = \frac{G.m_{1}.m_{2}}{r^{2}}

where m_{1} and m_{2} are masses

           G =Garvitation constant

          r = distance between two masses

Now since the planets, stars and galaxies are electrically neutral, therefore they have zero electrical charge and so electro magnetic forces have no affect on  these planets, stars and heavenly bodies.

     Whereas the masses of the heavenly bodies are very large, so they are largely affected by the gravitational force since Gravitational force is directly proportional to the product of the masses of a body.

Therefore, though the electromagnetic force is stronger than the gravitational force, the electromagnetic force does not dominate the forces in the heavenly bodies as they as not electrically charged.

if quasars often resemble little blue stars, what was it about them that so surprised astronomers when they were dis­covered?
Anna11 [10]

Quasar is famous for being an intergalactic object which is billions of years away from the earth yet can still be seen, unlike the other star body, unlike giant galaxies.

Hence, the fact that quasars can be detected from distances where even the biggest and most luminous galaxies cannot be seen means that "they must be intrinsically far more luminous than the brightest galaxies."

This condition, including other related evidence gotten in recent years concerning our galaxy, has shown that quasars are probably the central nuclei of very distant, very active galaxies.

The surprising thing was that quasars and active galaxies have a lot of mass in the center of the very small volume of the space.

Therefore, the surprising thing about quasars was that due to this mass and energy they are 100 times more luminous than Milky Way which means they have high recession velocity and a very large amount of red-shifting.
