Question

6
Hydrogen has three isotopes namely Protium, Deuterium and Tritium. Which is the incorrect statement?
1) Isotopes differ from one another in respect of presence of neutrons
2) All except protium has neutrons
3) Ratio of their atomic masses is 1:2:3
4) Ratio of their abundance is 1:2:3​

Answer 1

Answer:

Hydrogen has three naturally occurring isotopes: 1 H (protium), 2H (deuterium), and 3H (tritium). Other highly unstable nuclei (4H to 7H

Answer 2

Hydrogen has three isotopes namely Protium, Deuterium, and Tritium. 4) Ratio of their abundance is 1:2:3​ is the incorrect statement.

Isotopes of hydrogen:

• The elements hydrogen, deuterium, and tritium each have one isotope.
• Because the isotopes have varying amounts of neutrons, they are different.
• Deuterium has one neutron, tritium has two, and hydrogen has none.
• There is only one proton in each hydrogen isotope, however, these isotopes have different numbers of neutrons in their atoms.
• The heavier isotopes result from the additional neutrons; tritium is three times as heavy as regular hydrogen (also known as the proton) and deuterium is twice as heavy.
• The most prevalent isotope of the element hydrogen, proton, also known as hydrogen-1, has one proton, one electron, and no neutrons.
