Lesson #17 Isotopes of carbon and chlorine

Isotopes of carbon:

Carbon has there isotopes. Carbon-12 , carbon-13, and carbon-14. Almost all the carbon is carbon-12. Its symbol is 12C. It has six neutrons and protons. Carbon-13 has symbol 13C. It has seven neutrons and six protons. Carbon-14 has symbol 14C. It has eight neutrons and six protons. Different forms of carbon are black or greyish black solids except diamond. They are odourless and tasteless. They have high meting and boilling points and are insoluble in water.

Natural abundance of isotopes of carbon:

Carbon-12 = 98.8%
Carbon-13 =1.1%
Carbon-14 =0.009%

Isotopes of chlorine:

Ther are two natural types of chlorine. Chlorine-35 and chlorine-37. There symbols are 35Cl and 37Cl An atom of chlorine-35 has 17 protons and 18 neutrons. An atom of chlorine-37 has 17 protons and 20 neutrons. Chlorine is a gretyish yellow gas with sharp pungment irritating smell. It is fairy soluble in water.

Natural abundance of isotopes of chlorine:

Chlorine-35 = 74.77%
Chlorine-37 =24.23%
