  2. Isotopes of chlorine occur in nature predominantly in a 3:1 ratio. Chlorine-35 is the most abundant isotope, comprising about 75% of naturally occurring chlorine, while chlorine-37 makes up the remaining 25%.

  3. Isotopes of an element differ in their number of neutrons within the nucleus while retaining the same number of protons. This variance in neutron count results in isotopes with different atomic masses.

  4. Isotopes of an element generally exhibit similar chemical properties due to their identical electron configurations, which determine their interactions with other atoms. However, differences in atomic mass may result in slight variations in reaction rates or physical properties.
