Question

What are isotopes? Name the three isotopes of hydrogen. Also give their atomic number and mass number.

Answer 1

Answer:

Hydrogen has no neutron, deuterium has one, and tritium has two neutrons. The isotopes of hydrogen have, respectively, mass numbers of one, two, and three. Their nuclear symbols are therefore 1H, 2H, and 3H. The atoms of these isotopes have one electron to balance the charge of the one proton.

Answer 2

Answer:

Here is the answer for your question:

=>When two or more than two atoms having same atomic number but different atomic mass number are known as isotopes of each other.

The three isotopes of hydrogen are:

Hydrogen

Deuterium

Tritium

=>The atomic number is proton number of an element.The number of protons found in the nucleus of every atom of that element is called Atomic number.

Here,The three isotopes of hydrogen have only One Proton.Therefore,the Atomic number of the three isotopes of hydrogen is (Z=1).

=>The mass number is the total number of protons and neutrons in a nucleus of an atom.

Therefore, the mass number of the isotopes of hydrogen are 1,2,3 respectively.

So,The symbols are: ¹H,²H,³H.
