SAQ : In 92X235 how many of electrons protons and neutrons are there?

Question

In ₉₂X²³⁵, how many of electrons, protons and neutrons are there?

Answer

The isotope ₉₂X²³⁵ represents an atom of uranium.

In this isotope:

• The number of protons (atomic number) is 92
• The number of electrons in a neutral atom is also 92
• The number of neutrons is equal to the mass number minus the atomic number: 235 – 92 = 143

Therefore, this isotope has 92 protons, 92 electrons, and 143 neutrons.
