CBSE Class 10 Science Carbon and its compounds introduction
|
The amount of carbon present in atmosphere is 0.03 % and the amount of carbon present in the earths crust present is 0.04 %.
Each hydrogen shares its only electron with one of the electrons to form 4 single bonds .In an electron dot structure electrons are represented as dots .
Hint not available.
Carbon always forms covlent bonds as it can niether lose 4 electrons as it would require a lot of energy to remove 4 electrons leaving behind the nucleus with 6 protons nor it can gain 4 electrons as it will be difficult for the nucleus with 6 protons to hold on to 10 electrons.
Hydrogen shares its only outermost electron with another Hydrogen to form covalent bonds.
Covalent bonds are always formed by the sharing of electrons between two atoms.
Covalently bonded molecules are seen to have strong bonds within the molecules but intermolecular forces are small.
The amount of carbon present in atmosphere is 0.03 % and the amount of carbon present in the earths crust present is 0.04 %.
The manner in which carbon atoms are bonded to each other makes all the difference .As in diamond dismond each carbonatom is bonded to four other carbon atoms giving it a three diamensional rigid structure whereas in graphite each carbon atom is bonded to three other carbon atoms in the same plane giving a hexagonal array.
Hydrogen shares its only outermost electron with another Hydrogen to form covalent bonds.
