Trends in the properties of group-13 elements | The p-block elements | Chemistry | Khan Academy
In this video, we will look at the various properties of the group-13 elements like atomic radius, density, ionisation enthalpy, reducing property and electronegativity and find out how and why they vary within the group.
00:15 - Electronic configurations of the group-13 elements.
00:56 - Is boron a non-metal or a metalloid?
01:51 - Poor shielding effect of d and f orbitals.
03:18 - Does atomic radius decrease uniformly throughout the group?
04:45 - Why does density show a decreasing trend?
05:53 - Variation in ionisation enthalpy in the group-13.
07:09 - Reducing property of group-13 elements.
08:02 - Are heavier members more electronegative than their lighter counterparts?
