Question

How can helium exist in three different forms

Answer 1

Explanation:

Helium exists in three different forms due to the phenomenon of isotopy. Isotopy is the existence of two or more atoms of the same element having the same atomic number but different mass numbers due to the differences in the number of neutrons in their nuclei.

• The atoms of these elements are called isotopes.
• This is why Helium can exist in three different forms.
• Isotopes have the same electronic configuration but with the same chemical properties.
