Transition elements and Qualitative analysis Flashcards
1
Q
Define a transition element
A
A D-block element that forms at least one stable ion with a partially filled d sub-shell
2
Q
What are the two elements in d-block that are not considered transition metals
A
Scandium and Zinc
3
Q
Why are Scandium and Zinc not considered transition metals
A
Scandium form Sc3+ ions, where the d orbitals are empty
Zinc only forms Zn2+, where the d orbital is full
4
Q
Which electrons do transition metals loose first when forming ions
A
4s
5
Q
What are some physical properties of transitions elements
A
Metallic
High density
High melting and boiling point
Shiny
Good conductors
