Trasnsition Metals

Question 1

Transition metals

Answer 1

Form at least one stable ion with a partially filled d sub shell

Question 2

D block element

Answer 2

Element which has an atom with its highest energy electron in a d sub shell/ orbital

Question 3

Complex ion

Answer 3

Complex ion are formed by the co ordination if a lone pair of electrons from a donor (ligand) to an atom or cation (acceptor) which has empty orbitals to accommodate

Question 4

Ligand

Answer 4

Ion or molecule that is capable of donating one or more lone pairs of electrons via a coordinate bond to a central metal atom or ion in a complex

Question 5

Monodentate ligand

Answer 5

Uses only one lone pair of electrons to form a coordinate bond with a central metal atom or ion in a complex

Question 6

Polydentate / chelating ligand

Answer 6

Uses many lone pair of electrons to form more than 2 coordinate bonds with a central metal atom or ion in a complex

Question 7

Coordination number

Answer 7

Number of coordination bonds from the ligand to the central metal atom or ion in a complex

Question 8

Deprotonation

Answer 8

Removal of a proton/ H+ ion from a substance
