How is mercury different than other metals?
- Mercury is liquid at room temperature.
Is salt an element? explain.
- No, salt is a compound. Table salt refers to NaCl, composed of elements Na and Cl
Why are there more elements now than there were century ago?
- No
Why is table salt no poisonous?
- Table salt dissolves in water to form Na+ and Cl- both of which can be managed be excreted/regulated by the Kidneys (since they are charged)
A compund is formed when elements join through a _______? * chemical bond
2 of the 3 elements that make up ammonia also make up water. What is the third element______? * Nitrogen, N

Mercury is a liquid at ordinary conditions.
Salt is not an element. Salt can be melted to a liquid, an electric current passed through the liquid, and the constituent elements sodium and chlorine isolated at the electrodes.
Table salt is indeed poisonous. As the 16th Century scientist Paracelsus pointed out, "Poison is in the dose." He meant that if you eat enough, it will be fatal.
Chemical bond.
You have mis-asked this question. Ammonia is made up of nitrogen and hydrogen. Water is made up of hydrogen and oxygen. The element common to them both is hydrogen.
It may be that someone thinks that "ammonia" is ammonium hydroxide, NH4OH, which is ammonia dissolved in water. Such a person may think that "ammonia" and water contain hydrogen and oxygen, but that only "ammonia" contains nitrogen also. Such a person may be Homer Simpson's chemistry teacher.

Mercury is a liquid at room temperature.
Salt is an ionic compound composed of to elements, sodium and chlorine
There now are non-natural elements, which are made in cyclotrons (atom smashers/particle accelerators).
The ions in table salt, sodium and chloride (Na+, Cl-) stay in solution in the body and to not attach to other atoms or molecules, to form toxic compounds.
Ammonia is NH3. Ammonium hydroxide, NH4OH, is what you clean with. Hydrogen and oxygen are in ater, Nitrogen is not.

looks like you need to do a bit of research, because your doing an essay!
I would give you the answers, but it wouldn't help you learn the subject
