Class of chemical bonds where the valence electrons are shared between atoms.
00:03
These are typically non -metals, so we're looking at the p block primarily, which are quite electronegative, and the formation of a covalent bond allows for the non -metals to obey the octet rule and become more stable as a result by having eight valence electrons.

So here we're looking at the cbr bond length in cbr4.
00:27
This is one nine one pica meters, where pico is 10 to the minus 12.
00:31
The brbr bond length in br2 is 2 to 8 pique meters.
00:40
So because the bond length is the distance between the two nuclei, the radius of bromine atom should be 2 to 8 piquemeters divided by 2, 114 pachometers.
00:52
So therefore the bromine atom has a radius of 114 piquemeters and so we can calculate the radius of the carbon atom in cbr4 by taking away the bond length, of by taking away the radius of the bromine atom from the bond length of carbon.

So that is adjoined to bromine...
