Question 1

what is a transitional metal

Answer 1

an element that forms a 1 or more stable ions with incompletely filled d-orbitals

Question 2

what are the characteristics of transition metals (6)

Answer 2

1. hard solids
2. high Mp and Bp
3. act as catalysts
4. form coloured ions and coloured compounds
5. form ions with different oxidation number
6. form ions with incompletely filled d-orbitals

Question 3

why isn’t Zn and Sc considered to be transition metal

Answer 3

they only form one ion and their compounds aren’t coloured

Question 4

what transition metals don’t fit within the electronic configuration

Answer 4

Cu. Cr since they only fill one electron in the 4s orbital before they fill in the D orbital, where usually the 4s orbital would be full entirely

Question 5

high oxidation number ions form

Answer 5

only in complex ions, as Mn^7+ cant occur but Mn can have 7+ in ions such as MnO4^-

Question 6

when transition metals loose their electrons they first lose them from which orbital

Answer 6

their 4s

Question 7

where are transition metals with higher nuclear number less likely to have a high oxidation number

Answer 7

because their is a stronger electrostatic force so it is less likely that their electrons are used in bonding
