• Protons.
• Neutrons.
• electrons.

Useful and Interesting Atom Facts and Trivia

• There are three parts to an atom.
• Atoms are the smallest particles that make up elements.
• Atoms are mostly empty space.
• There are over 100 different kinds of atoms.
• The components of an atom are held together by three forces.

They’re typically made up of three main parts: protons, neutrons and electrons. Think of the protons and neutrons as together forming a “sun”, or nucleus, at the centre of the system. The electrons orbit this nucleus, like planets. If atoms are impossibly small, these subatomic particles are even more so.

Here are some examples of atoms:

• Neon (Ne)
• Hydrogen (H)
• Argon (Ar)
• Iron (Fe)
• Calcium (Ca)
• Deuterium, an isotope of hydrogen that has one proton and one neutron.
• Plutonium (Pu)
• F-, a fluorine anion.

Democritus

Dr. Max Perutz, whose success in elucidating the structure of the hemoglobin molecule helped give birth to the field of molecular biology and brought him the Nobel Prize in Chemistry in 1962, died on Wednesday at a hospital near his home in Cambridge, England.

Dalton’s atomic theory was accepted by many scientists almost immediately. Most of it is still accepted today. However, scientists now know that atoms are not the smallest particles of matter. Atoms consist of several types of smaller particles, including protons, neutrons, and electrons.

This section explains the theories that Dalton used as a basis for his theory: (1) the Law of Conservation of Mass, (2) the Law of Constant Composition, (3) the Law of Multiple Proportions.
