Mg (magnesium)
Silicon aka Si
Like most elements, calcium is a solid.
Calcite is not an element. It is a mineral which is made up of the elements calcium, carbon, and oxygen.In chemistry it is known as the compound calcium carbonate, CaCO3
One is magnesium. Other is Strontium. One below and one above Calcium in periodic table column.
Calcium is in group 2/IIA, so the other elements in that group would be expected to behave most like calcium.

Like most elements, calcium is a solid.
Most metals react with acids to give off hydrogen. Only very nonreactive metals, like gold and platinum do not react with metals. An example would be: Calcium + Hydrochloric Acid = Calcium chloride + Hydrogen gas (Ca +2 HCl = CaCl2 + H2)

The iron will not react unless you react it with calcium chloride. This is because Chloride is very electronegative (it has a high affinity for electrons) Both iron and calcium are not very electronegative and would like to give away their electrons. The Chloride ion accepts these electrons to get a full valent shell.

calcium floats on wahter because the hydrogen gas evolved on reaction sticks to the walls of the container where reaction is taking place....
