Answer:
Normal, neutral helium atoms that still have both electrons are called He I. Under conditions (temperatures around 60,000 to 80,000 kelvins) that exist in the Sun's atmosphere, helium atoms are ionized to form He II ions. These ions emit extreme ultraviolet (EUV) radiation at a wavelength of 30.4 nm (304 Å).

Answer:
The ionisation energy of a singly ionized helium ion is equivalent to the kinetic energy of the first orbit.
Singly ionized helium atom contains only 1 electron. The energy required to remove this electron completely is called ionization energy.
This electron is present in the first orbit. Hence, this energy is also equal to the kinetic energy of the first orbit.
In short:-
No, they are not same!!
