5.
Why are ionisation energies endothermic?
Energy is released when bonds form
Energy is needed to overcome nuclear attraction for the electron
Electrons repel the nucleus
Ions are more stable than atoms

Na+
F-
Mg2+
K+
7.
Which statement best describes First ionisation energy?
The energy required to remove one electron from each atom in one mole of gaseous atoms to form one mole of gaseous 1+ ions.
The energies needed to remove each electron in turn from an atom, forming ions of increasing charge.
The number (n) of the main energy level or shell an electron occupies.
Species that have the same number of electrons and electron configuration, e.g. Na+, Ne, F-.
8.
Which statement best describes Isoelectronic?
A region of space around the nucleus that can hold up to two electrons with opposite spins.
Species that have the same number of electrons and electron configuration, e.g. Na+, Ne, F-.
The number (n) of the main energy level or shell an electron occupies.
Electrons fill orbitals in order of increasing energy.
9.
Which statement best describes Hund's rule?
Species that have the same number of electrons and electron configuration, e.g. Na+, Ne, F-.
Electrons occupy orbitals of equal energy singly, with parallel spins, before pairing.
A region of space around the nucleus that can hold up to two electrons with opposite spins.
The energies needed to remove each electron in turn from an atom, forming ions of increasing charge.
10.
Which statement best describes Successive ionisation energies?
The energies needed to remove each electron in turn from an atom, forming ions of increasing charge.
The number (n) of the main energy level or shell an electron occupies.
A group of orbitals of the same type and energy within a shell (s, p, d, f).
Species that have the same number of electrons and electron configuration, e.g. Na+, Ne, F-.
