- 1What is the set up of the atom?a tiny, positively charged nucleus at the centre of the atom, nucleus is surrounded by a 'cloud' of negative electrons
most of the atom is empty space. - 2What is the relative mass and relative charge of the proton?Relative mass = 1
Relative charge = +1 - 3What is the relative mass and relative charge of the neutron?relative mass = 1
relative charge = 0 - 4What is the relative mass and relative charge of the electron?relative mass = 1/2000
relative charge = -1 - 5What is an isotope?an isotope is an atom that contains the same amount of protons and electrons but a different amount of neutrons
- 6What is an ion?Ions are electrically charged particles formed when atoms lose or gain electrons
- 7Definition of relative atomic massaverage mass of an atom relative to 1/12 of the mass of a carbon-12 atom
- 8Definition of relative isotopic massmass of a particular isotope relative to 1/12 of the mass of a carbon-12 atom
- 9What is an orbital?an orbital is a region which can hold up to 2 electrons with opposite spins
- 10What shape are s orbitals?they are spherical and come in sets of 1
- 11What shape are p orbitals?they have a dumbbell/hourglass shape and come in sets of 3
- 12What is the order of the orbitals?1s2s2p3s3p4s3d4p...
- 13Where are the different orbitals in terms of the periodic table?
