The Atom

The three basic components of an atom are:

• protons, neutrons, and ions
• protons, neutrons, and electrons
• protons, neutrinos, and ions
• protium, deuterium, and tritium

The nucleus of an atom consists of:

• Electrons
• Neutrons
• Protons and Neutrons
• Protons, neutrons, and electrons

An element is determined by the number of:

• Atoms
• Neutrons
• Electrons
• Protons

A single proton has what electrical charge?

• no charge
• positive charge
• negative charge
• either a positive or negative charge

Which particles have approximately the same size and mass as each other?

• Neutrons and electrons
• electrons and protons
• protons and neutrons
• none - all are different in terms of size and mass

Which two particles would be attracted to each other?

• Electrons and neutrons
• Electrons and protons
• Protons and neutrons
• All particles are attracted to each other

According to atomic theory, electrons are usually found:

• In the atomic nucleus
• Outside the nucleus, yet very near it because they are attracted to protons
• Outside the nucleus - most of an atom's volume is the electron cloud
• Anywhere they want to be - no particular location is more likely than any other
