Ionization energy is the energy needed to eject an electron from an atom or ion. Calculate the ionization energy, I E , of the one‑electron ion He + . The electron starts in the lowest energy level, n = 1 .

Ionization energy of is 54.4 eV.

Explanation:

where,

= energy of  orbit

n = number of orbit

Z = atomic number

Energy of n = 1 in an hydrogen like atom:

Energy of n = ∞ in an hydrogen like atom:

Ionization energy of =

answer: lol

explanation:

lol

why is arctic sea ice important? arctic sea ice keeps the polar regions cool and moderate global climate. sea ice has a bright surface; 80 percent of the sunlight that strikes it is reflected back into space. as sea ice melts in the summer, it exposes the dark ocean surface.
