Carbon can neither lose four of its electrons nor gain four electrons as both the processes
require extra amount of energy and would make the system unstable. Therefore, it
completes its octet by sharing its four electrons with other carbon atoms or with atoms of
other elements. The bonds that are formed by sharing electrons are known as covalent
bonds. In covalent bonding, both the atoms share the valence electrons, i.e., the shared
electrons belong to the valence shells of both the atoms.
Here, carbon requires 4 electrons to complete its octet, while each hydrogen atom requires
one electron to complete its duplet. Also, chlorine requires an electron to complete the
octet. Therefore, all of these share the electrons and as a result, carbon forms 3 bonds
with hydrogen and one with chlorine.

Though aluminium is a highly reactive metal, it is resistant to corrosion. This is because aluminium reacts with oxygen present in air to form a thin layer of aluminium oxide. This oxide layer is very stable and prevents further reaction of aluminium with oxygen. Also, it is light in weight and a goRead more
Though aluminium is a highly reactive metal, it is resistant to corrosion. This is because aluminium reacts with oxygen present in air to form a thin layer of aluminium oxide. This oxide layer is very stable and prevents further reaction of aluminium with oxygen. Also, it is light in weight and a good conductor of heat. Hence, it is used to make cooking utensils.
Sodium, potassium, and lithium are very reactive metals and react very vigorously with air as well as water. Therefore, they are kept immersed in kerosene oil in order to prevent their contact with air and moisture.
