The challenge arises in determining the appropriate mass to assign to a chlorine atom because it consists of a mixture of isotopes with different masses.
Discussion Forum Latest Questions
Chlorine isotopes occur naturally in the ratio of 3:1, with masses 35 u and 37 u, respectively.
Isotopes of an element differ in their physical properties, such as mass, density, and stability, due to variations in their atomic masses caused by differing numbers of neutrons.
Yes, isotopes of an element have similar chemical properties because they have the same number of protons and electrons, determining their chemical behavior.
Isotopes are atoms of the same element with the same number of protons but differing numbers of neutrons, resulting in different mass numbers.
