To write a complete nuclear symbol, the mass number is placed at the upper left (superscript) of the chemical symbol and the atomic number is placed at the lower left (subscript) of the symbol. The complete nuclear symbol for helium-4 is drawn below.
How do you write subscripts in chemistry?
For formula writing, use _ (underscore) for subscripts and ^ (carat) for superscripts. If there is more than one character in the subscript or superscript, wrap the characters with braces . If you’d like your chemical formulas without the italics, use advanced view and ext to enclose the elements.

What is an isotopic symbol?
Isotope Notation Isotopes can also be defined in standard, or “AZE”, notation where A is the mass number, Z is the atomic number, and E is the element symbol. The mass number “A” is indicated with a superscript to the left of the chemical symbol “E” while the atomic number “Z” is indicated with a subscript.

What is a nuclear symbol and hyphen notation?
Note: in hyphen notation, the number after the hyphen is the mass number (protons + neutrons). For the Periodic Table, the Atomic Number is on top and the average atomic mass is on the bottom. For nuclear notation, the mass number of the isotope goes on top and the atomic number goes on the bottom.

How should O2 be written?
Why is oxygen written as O2? The difference between oxygen (O) and oxygen (O2 )is that the former is an oxygen atom while the latter consists of two O atoms bound together, forming a molecule also called oxygen. Oxygen is usually found as a diatomic gas. Therefore, we write it as O2.
