A given isotope contains 92 protons, 146 neutrons, and 86 electrons. What is the chemical symbol for this isotope?
Solution:
The number of protons is equal to the atomic number which can be found on the Periodic Table and tells us the identity of the element. Element with 92 atomic number is U. The number of protons + neutrons is equal to the mass number. 92+146 = 238. The mass number goes on the top left corner of the symbol. The atomic number goes on the bottom left corner of the symbol. Finally there are 86 electrons and 92 protons. Electrons have a -1 charge and protons have a +1 charge. -86+92=+6, which is the charge of the ion.
²³⁸₉₂U⁶⁺
