1.1 Particle Theory

Which subatomic particles are found in the nucleus of an atom?

• Protons

• Electrons

• Protons and electrons

• Protons and Neutrons

The electron is found

• Inside the nucleus

• Bound to the Neutron

• Orbiting the nucleus

• Bound to the Proton

In the periodic table, elements are organized by

• Atomic mass

• the number of protons

• the number of neutrons

• the number of electrons

A water is heated

• molecular motion increases

• molecular motion decreases

• molecular motion stops

• there is no change in molecular motion
