2.1.1, 2.1.2 Atomic Structure

• PROTON - Give it's position, relative mass and charge Nucleus 1+1
• NEUTRON- give it's postion, relative mass and charge Nucleus10
• ELECTRON- give it's position, relative mass and charge Orbtials1/18001-
• Define isotope Isotopes are atoms of same element with the same number of protons, but different numbers of neutrons
• Why do isotopes have similar chemical properties? They have the same electronic structure
• Why do isotopes have slightly varying physical properties? They have different masses, due to different number of protons
• Define relative isotopic mass the mass of one isotope compared to 1/12 of the mass of one atom of carbon-12
• Define relative atomic mass the weighted mean mass of one atom compared to 1/12 of the mass of one atom of carbon-12
• Define relative molecular mass the average mass of a molecule compared to 1/12 of the mass of one atom of carbon-12
