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?
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 atomicnumber 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 samenitrogen element.
