Answer:

See explanation.

Explanation:

Hyphen notation is simply a way we have of naming isotopes.

In order to use hyphen notation properly, you must

  • start with the name of the element
  • add a hyphen
  • add the mass number of the isotope

Let's take, for example, #""^14"C"#, one of the stable isotopes of carbon, #"C"#. The hyphen notation for this isotope would be

carbon-14

Here you have the name of the element written first, followed by the hyphen and by the mass number, which in this case is #14#.

Another example could be #""^238"U"#. Here you are dealing with an isotope of uranium, #"U"#, which has a mass number equal to #238#. This means that its hyphen notation will be

uranium-238
