A coordination complex is made up of . (Choose one) Selected IncorrectC. a transition metal center and alkaline earth metal ligands surrounding it. Answers: CorrectA. a Lewis acidic metal center with Lewis basic ligands surrounding it. B. an Arrhenius basic metal center with Lewis acidic ligands surrounding it. C. a transition metal center and alkaline earth metal ligands surrounding it. D. a Lewis basic metal center with Lewis acidic ligands surrounding it.

a Lewis acidic metal center with Lewis basic ligands surrounding it.

Explanation:

A lewis acid is a chemical specie capable of accepting a lone pair of electrons while a lewis base is a chemical specie capable of donating a lone pair of electrons.

In a coordination compound, a lewis acid(central metal atom/ion) accepts electron pairs from lewis bases (ligands). Any chemical specie called a ligand must possess at least one electron pair available for coordinate covalent bonding.

Coordination compounds are usually formed between transition metal atoms/ions and neutral molecules having lone pairs of electrons or anionc species .

it should have an internal chamber and two thermometers sticking out of the top. the internal chamber will also be closed off from the outside.
