Transition Metal Definitions Quiz

HideShow resource information

1. When forming ions in transition element chemisty, the 4s electrons are always removed

  • Before any electrons are taken from the 3d sub shells
  • A d-block element that forms an ion with an incomplete d sub shell
  • The 4s orbital fills before the orbitals in the 3d sub shell. The d block metals will have filled there 4s orbital before electrons are added to the 3d sub shell

  • Orange to colourless

3. Optical isomerism is a type of stereoisomerism where an ion

  • Can exist in two non-superimposable mirror images

5. A transition element is

  • A d-block element that forms an ion with an incomplete d sub shell
  • The 4s orbital fills before the orbitals in the 3d sub shell. The d block metals will have filled there 4s orbital before electrons are added to the 3d sub shell

I'm sorry about the last comment, my friend wrote it because he didn't want to accept that he got some answers wrong in this quiz. I just got 100% on this quiz and with it It helped enhance my knowledge on Transition Metals as a whole. Keep up with the resources guys!!!
