which of the elements below are defined as transition elements. you can choose more than one element

• niobium

• zinc

• vanadium

• platinum

• scandium

write the continuation of electronic configuration of Cu²⁺ ion

1s² 2s² 2p⁶ .................

Why is zinc not considered a transition metal?

• Zinc is not a transition metal because it gains two 4s electrons to give a 2+ion with full d subshell levels.

• Zinc is not a transition metal because it loses four 4s electrons to give a 4+ion with full d subshell levels.

• Zinc is not a transition metal because it loses two 4s electrons to give a 2+ion with full d subshell levels.

• Zinc is not a transition metal because it gains two 4d electrons to give a 2+ion with full d subshell levels.
