WebThe chemical symbol for Helium is He. It is a colorless, odorless, tasteless, non-toxic, inert, monatomic gas, the first in the noble gas group in the periodic table. Its boiling point is the lowest among all the elements. 28 pm 3 Li Lithium 121 pm Lithium Discoverer: Arfvedson, Johan August Element Category: Alkali metal WebFrom the periodic table, we see that the atomic number (number of protons) for the element carbon is 6. The name carbon-14 tells us that this isotope's mass number is 14. The chemical symbol for carbon is C. Now write the isotopic notation for carbon-14. 14 6 C We can determine the number of neutrons as 14 −6 = 8 neutrons. Example 2.
