Question

why do isotops show similar chemical proprties ? mention two uses of isotopes

Answer 1

We know that Isotopes have same atomic number.
So, they have same valency also.

Due to same valency Isotopes show similar chemical properties.

Two Uses of Isotopes are:
1) Isotope of Iodine is used in treatment of Goitre.
2) Isotope of Cobalt in used in treatment of Cancer.

Answer 2

The isotopes of an element have same atomic number ( Z ) i.e. the same number of electrons and same number of protons . Hence , they have identical chemical properties .

2) Isotopes of an element have same number of valence electrons and hence same valency .

USES OF ISOTOPES

1) Isotopes of hydrogen , oxygen , carbon are used to study the mechanisms of organic reactions .

2) Some radioactive isotopes are used for the treatment of cancer and other diseases .
