metalloids
Two or more substances may combine chemically under certain conditions and form compounds.
Substance that cannot be changed into a simpler substance under normal laboratory conditions are elements. A physical blend of two or more substances that are not chemically combined is a mixture.
Macroscopic properties of water, such as its liquid state under normal conditions, its ability to dissolve polar substances and its high boiling point
This is the simplest vapour-liquid separation device for gaseous mixtures. It can only be used when the boiling points of the substances are so different that essentially only one of them will condense into a liquid under suitable conditions.

semiconducters are substances that can conduct electricity under some conditions but not under other conditions
Yes.

Depends on the conditions that is held under; Pressure, Temperature. At ATM conditions it exists as a gas, but when stored as a pure substances, it is usually pressurized and cooled as a liquid.

To what, under which conditions?
Atomic energy is generated by splitting nuclear substances such as atoms of uranium, thorium, cheralite, zirconium under controlled conditions.
Repeatability...multiple experiments conducted under identical conditions serve to prove the results of the initial experiement.
