As another example, a totally ionized nickel atom contributes a nucleus of mass 58.7 plus 28 electrons; its molecular weight is then 58.7/29 = 2.02.

WebExplanation: This image of the active Sun was made using ultraviolet light emitted by ionized Helium atoms in the Solar chromosphere . Helium was first discovered in the Sun in 1868, its name fittingly derived from from the Greek word Helios, meaning Sun. Credit for the discovery goes to astronomer Joseph Norman Lockyer (born May 17, 1836).

Web19 apr. 2011 · Helium is a hydrogen-like atom. Using the fact that the ground state energy of hydrogen is 13.6eV, we can use the relation: E = 13.6eV (z^2/n^2) to calculate the energy levels of helium, where z is charge number and n^2 is the principle quantum number.
