A molecule is a group of atoms joined together by chemical bonds. The molecules of an 1_______ are identical and contain atoms of one type only. Oxygen gas, for example, has 2_______ made up of two oxygen atoms. The molecules of a compound are also 3_______, but in this case each molecule 4_______ atoms of more than one type. In water, for example, each molecule is made up of two hydrogen atoms and one oxygen atom. All gases, most liquids, and many nonmetallic solids consist of molecules.

There are uncountable combinations of atoms. For example, 4 carbon atoms combine with 10 1_______ atoms to make up a butane molecule. A glucose molecule is made from 6 carbon atoms, 12 hydrogen atoms and 6 oxygen 2_______. Cellulose, the principal molecule in the plant cell walls and also in wood, paper, 3_______, and many other materials, is a chain that can include up to 12,000 glucose molecules. A sugar molecule is made from carbon, hydrogen and oxygen atoms grouped in specific positions. When these same atoms are grouped in different positions they can form alcohol or starch. The different proportions and positions of the atoms produce the 4_______ forms of matter.

The English physicist Joseph Thomson made a major breakthrough in scientific understanding of the structure of the atom, proposing a model that became known as the Thomson atom. His work 1_______ practical proof on many of the new theories that were being put forward about 2________ structure. Several years later, in 1906, he received a Nobel Prize for physics for his research into the electrical conductivity of gases. Thomson was a 3_______ teacher and an outstanding scientist. Seven of his students and 4_______ also received Nobel Prize for their work.

Everything in the world is in motion. Some forms of motion we can see clearly, such as the flight of an airplane. But even objects that seem still, such as rocks and buildings, contains atoms (tiny particles) that move minutely, or vibrate. The Earth itself is moving around the sun, and the entire universe is expanding. All motion requires force to start, to change speed or direction, or to stop.

Your weight is the force that you exert on the Earth. It is a result of gravity acting on your body. Weight differs from mass: your mass is constant whatever the force of gravity. Scientists measure mass in kilograms. This indicates the amount of matter in your body. Scientists measure weight in newtons (N), and 1 kg equals a force of 9.81 N. On the Moon your weight will be much less than it is on Earth because of the less gravity.

Born in Edinburgh, the physicist James Clerk Maxwell has been described as the most brilliant scientist of the 1800s. His best-known work established a link between electromagnetism and light. This research later helped the German physicist Heinrich Hertz to build the first radio-wave transmitter. During his carrier, Maxwell produced new theories on many scientific problems of the day: the physical properties of gases; the nature of the planet Saturn’s rings; how humans perceive colors.
