300
One of the postulates of Dalton's Atomic Theory.
What is any one of 1) Atoms are composed of tiny indivisible particles called atoms, 2) Atoms of the same element are identical and different from the atoms of any other element, 3) Atoms of different elements can combine in simple whole-number ratios to form compounds, or 4) Chemical reactions are simply the rearrangement of atoms (not the changing of one type of atom into another).
300
Another name for a "row" on the periodic table, there are currently seven of them.
What is a period?
400
Chemistry done for its own sake, rather than for a specific reason.
What is pure chemistry?

The father of modern chemistry, he helped transform chemistry from a science of observation to the science of measurement it is today.
Who is Lavoisier?
500
A method of separating mixtures that takes advantage of differences in boiling points, rather than differences in particle size.
