Copper (II) ions are able to participate in co-ordinate covalent bonding because they
are coloured
are positively charged
have vacant d-orbital
have unpaired electrons
설명
Copper (II) ions have vacant d-orbitals. This means that they can accept a pair of electrons from a donor atom. When a copper (II) ion accepts a pair of electrons, it forms a co-ordinate covalent bond with the donor atom.
