Question

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.

Answer 1

The symbolic notation of an isotope of oxygen with 8 protons, 8 electrons, and 11 neutrons is 198O, also known as oxygen-19.

Step-by-step explanation:

The symbolic notation of an isotope with 8 protons, 8 electrons, and 11 neutrons is: 198O. In this notation, the atomic number (number of protons) 8 is written as a subscript, and the mass number (total number of protons plus neutrons) 19 is written as a superscript to the left of the chemical symbol for oxygen (O). This isotope of oxygen can also be referred to as oxygen-19.

Answer 2

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
