• what are the three subatomic particles?

  electron, proton, neutron
• electron is the negatively charged particle, proton is the positively charged particle, and neutrons have no charge
• what denotes the number of protons within an element?

  atomic number
• what is the amount of neutron and protons found in an atom's nucleus called?

  atomic mass
• what are charged atoms called?

  ions

  cation
• what is a negatively charged ion called?

  anion
• isotopes are nuclear species of the same elements, meaning that they have the same number of protons but differ in number of neutrons
• isotones are nuclear species of diff elements that have the same number of neutrons
• isobars are nuclear species of diff elements that have the same mass number
• matter is anything that occupies space and has mass
