O A certain quantity of energy is necessary to eject electrons from a metal A certain number of photons is necessary to eject electrons from a metal A certain temperature is necessary to eject electrons from a metal O A certain number of atoms is necessary to eject electrons from a metal O A certain speed of light is necessary to eject electrons from a metal

Consider a helium ion with one electron in the ground state. It turns out that it would take about 28 eV to remove this electron through ionization. Blue photons have an energy of about 4 eV. Can this electron emit about 7 blue photons. Is this true? Why or why not?

Quantum numbers arise naturally from the mathematics used to describe the possible states of an electron in an atom. The four quantum numbers, the principal quantum number (n), the angular momentum quantum number (e), the magnetic quantum number (m,), and the spin quantum number (m,) have strict rules which govern the possible values. Identify all allowable combinations of quantum numbers for an electron. n = 2, l = 1, mę = -1, mş = 1 n = 3, l = 1, mę = 1, mş = - Un = 2, l = 2, mẹ = 0, ms = - n = 5, l = 3, mẹ = -3, ms = - n = 4, l = 2, mẹ = 3, m, = + %3D O n = 3, l = -1, mẹ = 1, m, = -
