WebLithium is a classified alkali metal and its symbol is Li. Lithium is the 3rd element of the periodic table so its atomic number is 3. The atomic number of an element is equal to the number of protons and electrons in that element. Therefore, a lithium atom has three protons and three electrons. WebAfter hydrogen, helium is the second most abundant element in the universe. It is present in all stars. It was, and is still being, formed from alpha-particle decay of radioactive elements in the Earth. Some of the helium formed escapes into the atmosphere, which contains about 5 parts per million by volume.
