Ionisation Energy T.B.C
Cards in this deck (8)
- 1What is ionisation energy?The minimum energy needed to remove a mole of electrons from a mole of atoms in the gaseous state.
- 2What is ionisation energy measured in?(KJmol⁻¹)
- 3What can the first ionisation energy tell us?The structure of the atom and the electron.
- 4What happens as we go across a period on the periodic table?The nuclear charge increases making it more difficult to remove an electron.
- 5What is nuclear charge?The effective positive charge from the nucleus.
- 6What does going down a group have a result in? and Why does this happen?The first ionisation energy decreases as you go down because we gain another main energy level.
- 7What is ionisation energy?The energy required to remove a mole of electrons from a mole of atoms in the gaseous state it is measured in KJmol‾¹.
- 8Why does the first electron being removed require the least amount of energy? and why does the ionisation energy increase?Due to it being removed from a neutral atom and the energy would continue to increase because it is being removed from bigger ions, these are called successive ionisation energies.
