POINTS TO REMEMBER

Carbon is tetravalent. It has 4 electrons in the outer shell. Atomic number of Carbon is 6. There are 6 protons, 6 electrons and 6 neutrons in C12 element. Electronic configuration of Carbon is 2,4 so in first shell there are 2 electrons and 4 electrons in the outer shell. To complete the octet, Carbon must either give up 4 electrons or take 4 electrons. In either case the number of electrons involved are large for the number of protons inside the nucleus. So carbon resorts to sharing of electrons. This sharing ability of carbon with multiple atoms or molecules makes it a unique element in the periodic table and in nature.

THINK TANK

What makes Carbon so special in nature ?

Even though graphite and diamond are made of same element, their properties are completely different. Why ?

Can we chemically synthesize diamonds ?

How does the atomic size change for elements based on their bonds ?

What are hydrocarbons ?

What is the fundamental building block of humans ? Is Carbon present in us too ?
