How to write isotope notation?
Understand the Problem
The question is asking how to represent isotopes using isotope notation, which typically involves writing the element symbol along with its mass number and atomic number.
Answer
Place the atomic number as a subscript and the mass number as a superscript to the left of the atomic symbol.
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.
Answer for screen readers
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.
More Information
Isotope notation can be used to easily identify different isotopes of an element, which have the same number of protons but different numbers of neutrons.
Tips
A common mistake is to mix up the position of the superscript and subscript. Ensure the mass number (superscript) is on the top left and atomic number (subscript) is on the bottom left.
