Write the symbolic notation of an isotope of an element having 8 protons, 8 electrons, and 11 neutrons. click on the “templates” button template button and make use of the "stacked super/subscript" button button for entering stackes super/subscripts for entering the mass number and atomic number of the isotope. express your answer as an isotope.

Attached to this answer is the format of Isotope Notation that you can use for future reference. (Please open)

There are 8 Protons. The Atomic Number is the same number of an element's proton.

If you can see in the format, the mass number is calculated by adding the atomic number/protons and neutrons.

Mass number = 8 + 11
Mass number = 19

The image of the final answer is attached as well.
