Trends in the general properties | The d-block elements | Chemistry | Khan Academy

Description
In this video, we will discuss the trends in the general properties of transition elements like physical properties such as melting and boiling points, enthalpies of atomisation, atomic/ionic radius, and density.

great video!!

[@kisho2679]

Which are trends in the general properties of the f-block elements?

[@GreAse0MonKey27]

At 1:40 what's just happened..
Whom is increasing whom just don't know.
That part is above my head

[@GreAse0MonKey27]

At 2:03 "One electron per d-orbital is especially favourable for strong interatomic interaction"
Can anyone please explain me what's happening?????

[@ultimatestar9873]

if One electron per d-orbital is filled there is space for one more electron in the every orbital. Therefore , 5 electron of other atom can make bond ....
