Most people describe water as a 1_______ liquid. They know that in very cold conditions it becomes a solid called 2_______, and heated on a fire becomes a vapour called steam. But water, they say, is a liquid. Now we know that water consists of molecules composed of two 3_______ of hydrogen and one atom of oxygen, which we describe by the formula H2O. This is equally true of the solid called the ice and the gas called steam. Chemically there is no difference between the gas, the liquid, and the solid, all made up of 4_______ with the formula H2O.

Radioactive substances are composed of unstable atoms that break down and release high-level energy called radiation. These atoms eventually form new elements. There are three types of radiation, known as alpha rays, beta rays, and gamma rays. Alpha rays consist of four atomic particles: two protons and two neutrons. They are the weakest type of radiation and have a positive electrical charge. Beta rays are more powerful and are composed of atomic particles called electrons, which have a negative charge. Gamma rays are the most powerful and a pure form of energy with no mass and no charge.

The French chemist Antoine Lavoisier is regarded as the father of modern chemistry. He is remembered particularly for his work on gases, gunpowder, and combustion. He discovered and named both oxygen and hydrogen, observing that these two gases combine to produce water. This led him to describe elements and compounds, giving many the names by which they are known today. Lavoisier and his wife Marie were meticulous scientists who produced some important manuals describing scientific experiments. In the aftermatch of the French Revolution, Lavoisier was executed by revolutionaries.
