Joe follows the procedure below to make a compass.
1. move a magnet from the top of a needle to its point fifty times.
2. lay the needle on a cork that is floating in a bowl of water.
3. observe the direction that the needle points.
what is the purpose of step 1?

a. to give the needle an electric charge
b. to make the needle sharper
c. to magnetize the needle
d. to flatten the side of the needle

The answer is C. By moving the magnet severally over the top of a needle, the atoms in the needle align themselves with the magnetic field of the magnet. This, therefore, turns the needle into a small and weak magnet. This way, the needle can align itself with the earth’s magnetic field and hence point in the direction of the poles.

the answer is 1 i believe

oxygen, selenium, tellurium, and polonium.

they're all from the same group as sulfur (group 16).
