year 9 atoms, elements and compounds

Which two particles make up the nucleus of an atom?

• protons and electrons
• protons and neutrons
• molecules and compounds
• neutrons and electrons

In an atom, what is the number of protons equal to?

• The number of electrons
• The number of molecules
• The number of neutrons

This is any combination of two or more atoms from different elements that are chemically combined.

• compound

• molecule

• element

• pure substance

This is a one or two letter representation of each element that is generally close to the element's name. The first letter of this will ALWAYS be capitalized.

• chemical symbol

• chemical number

• atomic number

• atomic mass

Particles in an atom that are neutral and have no charge are

• negatrons

• electrons

• neutrons

• protons

A particle that moves around the nucleus is a(n)...

• Proton
• Neutron
• Electron
• Quark

An atom with atomic number 6 would have how many protons

• 6

• 12

• 3
