The number of protons and neutrons in the isotopes of nitrogen is to be determined.
Isotopes are the two or more atoms that have same number of protons but different number of neutrons.
In the periodic table,
Mass number is the sum of number of neurons and number of protons present in the nucleus of the atom. Mass number is represented by A. Mathematically, mass number is calculated as:
Here, A is the
Answer to Problem 1PP
Explanation of Solution
The atomic number (Z) from the symbol for nitrogen is
The number of protons is same as the atomic number. So, the numbers of protons for both the isotopes of nitrogen are 7.
The total number of protons and neutrons is equal to the atomic mass. Therefore, the number of neutrons is calculated as follows:
Rearrange the above equation:
Here, A is the atomic mass of the element.
