Concept explainers
Interpretation: Difference between potassium-39, potassium-40 and potassium- 41 is to be explained and the isotope symbols for three isotopes of potassium are to be written.
Concept Introduction: An atom is made of particles called electrons, protons and neutrons. Atoms of one element are different from atoms of another element. Sometimes atoms of the same element are also different due to the different number of neutrons in them. Isotopes are atoms of the same element with a different number of neutrons.

Answer to Problem 3E
Potassium-39, potassium-40 and potassium- 41 are three isotopes of potassium. They are different in their masses or mass number. Potassium- 39 has an
Isotopes of potassium can be represented as follows:
Explanation of Solution
Given information:
Potassium- 39, potassium- 40 and potassium- 41 are three isotopes of potassium.
Isotope- Isotopes are atoms of the same element having different numbers of neutrons.The mass of an atom is the mass of a single atom for a single
Potassium occurs in nature in three forms. These three forms are called isotopes of potassium. One isotope of potassium has a mass of 39 amu. The other two isotopes have masses of 40 amu and 41 amu respectively. Potassium- 39, potassium- 40 and potassium- 41are isotopes of potassium. All these isotopes have the same number of protons; sothe number of neutrons in potassium- 39 is one less than in potassium- 40 and two less than in potassium- 41. Similarly,Potassium- 40 has one neutron less than Potassium- 41.
Isotope symbol- Symbols for three isotopes of potassium are given below:
The mass of each isotope is shown as the superscript number on top. This is a whole number calculated as the sum of the number of protons and neutrons in the atom. It is also called the mass number. The subscript number is the
The mass number of an atom is the sum of the number of protons and neutrons in an atom. Isotopes have different mass numbers but the same atomic number.
