Chemists

100

Scientists who study elements and compounds

Chemists

200

Antient "chemists" who believed in a mixture of science and magic to change ordinary metals into gold.

Alchemists

300

First person to use reason and experiments to disproof much of what the alchemists believed. This scientist discovered the relationship between pressure and volume of a gas so well that it was made into a law of science.

Robert Boyle

400

This scientist was the first one to identify Hydrogen, and showing that water is made up of hydrogen and oxygen.

Henry Cavendish

500

This scientist proved that neither phlogiston nor dephlogisticated air were real. He called his new found air oxygen.

Antoine Lavoisier

Smelting

300

A substance of more than one element.

Compound

400

A substance composed of two or more metals OR one or more metals and certain non-metals, for example, steel from iron and carbon.

Alloy

When the same element can have different numbers of neutrons.

Element isotope

Procedures and Laws

100

Law that states that in every reaction there is an equal quantity of matter before and after the operation, or more simply, in a chemical reaction, the total amount of matter of the reaction compounds remains constant. 

Conservation of Matter

200

Law that states that in an compound, the constituent elements are always present in a definite proportion by weight.

Law of Definite Proportions 

300

Separation of liquid compounds into elements or simpler compounds by vaporization (using fire) or evaporation (using the sun)

Distillation

400

The process of using batteries or voltaic piles to decompose a compound.

Electrolysis

500

When metals are burned in air, a whitish powder forms upon them caused by the addition of oxygen to the metal during burning. What is this process called?

Calcination

Atomic number

400

Number that shows the number of protons in the nucleus of an atom of an element

Atomic number

500
