How do you write the atomic symbol for an isotope?
To write the symbol for an isotope, place the atomic number as a subscript and the mass number (protons plus neutrons) as a superscript to the left of the atomic symbol. The symbols for the two naturally occurring isotopes of chlorine are written as follows: 3517Cl and 3717Cl.
What is atomic symbol give example?
For this reason, the atomic number is sometimes not given when the atomic symbol is written down. For example both 12C and13C have Z = 6 – they just differ in the number of neutrons and so have different mass numbers.
