A certain atom has a nucleus containing seven protons and eight neutrons, and has seven electrons moving around the nucleus. This atom is an isotopic form of which element?

Sagot :

This atom with 7 protons and electrons is an isotopic form of nitrogen element.

ISOTOPES:

  • Isotopes are atoms of the same element with the same atomic number but different mass numbers.

  • Isotopes of the same element differ in the number of neutrons they contain, which is directly responsible for the difference in mass numbers.

  • The number of protons of an element is the atomic number of that element. Hence, if an atom has 7 protons and 7 electrons, this means that the atom is that of nitrogen.

  • However, the atom has 8 neutrons, meaning that it is an isotope of the same nitrogen element.
