Question

Q.3 The diagram represents an isotope of hydrogen [H]. Answer the following:
1. Are isotopes atoms of the same element or different elements.
2. Do isotopes have the same atomic number or the same mass number.
3. If an isotope of 'H' has mass no. = 2, how many electrons does it have.
4. If an isotope of 'H' has mass no. = 3, how many neutrons does it have.
5. Which sub-atomic particles in the 3 isotopes of 'H' are the same.
At, no. = 1
Mass no. = 1​

Answer 1

Explanation:

Isotopes are atoms of the same element.

Same atomic number

One electron

Two neutrons (A= P + n)

Protons and electrons in each isotope are the same.
