Question
If an element has 13 protons and 14 neutrons, which of the following will be the correct representation of an element?
Hint:
The element that has 13 protons and 14 neutrons can be represented as
The correct answer is:
- The number of protons will be equal to the number of electrons in an atom.
- The mass number is the sum of the number of protons and neutrons.
- If the atom has 13 protons and 14 neutrons, its mass number would be 27.
- The number of electrons will be 13.
- The element that has 24 mass numbers and 13 electrons can be represented as .
