Question 1 Show covalent bonding in hydrogen molecule?
Question 2 Show covalent bonding in oxygen molecule?
Question 3 Show covalent bonding in nitrogen molecule?
Examples of covalent molecules
(1) Hydrogen molecule
The atomic number of hydrogen is 1.It has 1 electron in its outermost shell.It needs 1 more electron to complete its shell.Therefore H atom shares its electron with another hydrogen atom.Thus there is a single covalent bond.
(2) Oxygen molecule
The atomic number of oxygen is 8.It has 6 electron in its outermost shell.It needs 2 more electron to complete its shell.Therefore O atom shares its electron with another oxygen atom.Thus there is a double covalent bond.
(3) Nitrogen molecule
The atomic number of nitrogen is 7.It has 5 electron in its outermost shell.It needs 3 more electron to complete its shell.Therefore N atom shares its electron with another nitrogen atom.Thus there is a triple covalent bond.
Thank you Shilpi. The website is clean and easy to follow.
Thanks mam for this answer but i need more examples of covelent molecules
