Answer:
Covalent bonds are the types of Bond which is formed by sharing of an electron between two atoms of same element or two different elements. The bond which is formed by the completely lost or gained of an atom is known as ionic bond.
Explanation:
The most common example of covalent bond is formed from carbon atom. The valence of carbon atom is 4. Therefore, it is very hard to gain or lose an electron from the carbon atom. Therefore, the carbon tends to share the electron instead of completely losing or gaining the electron.
Ionic bond is very common and it can be formed by many elements from the periodic table. Ionic bond is more stable and stronger when compared to the covalent bond in nature.
Water means it is the mixture of hydrogen and oxygen. As we know that
hydrogen is colourless as well as oxygen is also colourless gas.
So at last when hydrogen and oxygen reacts with one another and they
form H2O means water. If both are colourless so their product will also
be colourless. So water is seen colourless.
