Question
Predict the characteristic of transition elements(Ti to Cu) of atomic number 22 to 29.
- Good electrical and heat conductor.
- Have a decrease in atomic radius.
- Have two electrons in the 4s orbital.
- Have lower first ionization energy than the alkali metals.
Hint:
Due to lanthanide contraction atomic radii decrease
The correct answer is: Have a decrease in atomic radius.
The characteristic of transition elements(Ti to Cu) of atomic numbers 22 to 29, the atomic radii decreases as the nuclear charge increases
