Question

H and D isotopes of hydrogen form H2O and D2O with oxygen. Which of the following you

think right for the above observation.

(A)H and D have same number of protons

(B) H and D have same no. Of neutrons

(C) A and D have same no. Of electrons

(D)H and D have same mass number.​

Answer 1

Answer:

(C) H and D have same number of electrons

Explanation:

Isotopes are atoms which have the same atomic number but different mass numbers.

Hydrogen and deuterium have the same atomic number, i.e, they have the same number of protons and same number of electrons in neutral state.

Due to same number of electrons, their chemical properties are similar too. And hence, they form similar type of molecule with oxygen.
