Question

Nitrogen is more electronegative than oxygen. A nitrogen atom is smaller than an oxygen atom. The electron ionized from nitrogen experiences less electron-electron repulsion than the electron Ionized from oxygen. The electron ionized from nitrogen is a 2s electron, while the electron ionized from oxygen is a 2p electron. Which set of quantum numbers n, l, m_1, m_s is invalid? 1, 1, 0, -1/2 2, 0, 0, +1/2 3, 1, 0, +1/2 4, 3, 2, -1/2 What is the product of alpha emission from the isotope uranium-238?

Explanation / Answer

47) n = 1,2,3,...etc

l = 0 to n-1

ml = -l to 0 to + l

ms = +1/2 or -1/2

n,l,ml,ms

so that , A is invalid
