Question

which of the following orbit of He+ ions will have the same energy as that of second orbit of hydrogen atom?

Answer 1

Orbit four helium ion i.e. n=4 of He^(+) will have the same energy as that second orbit of Hydrogen atom i.e. of n=2 of the hydrogen atom. This is because we know that E alpha -Z^(2)//n^(2).

What is Helium?

• Helium is the gas and the second element of the periodic table with the chemical symbol He.
• It is a tasteless, colorless, and odorless gas that can be detected easily.
• Moreover, this gas holds the first position in the group of noble gases.
• The boiling and melting points of Helium are the lowest among other elements.
• The characteristics of the Helium ion are similar to a hydrogen atom.
