Question

17of24| Part A animation you can see that the electrons occupy different orbitals according to the energy level of each ontsital. A single box represents an otital The unpaired electron is represented as whereas the paired electrons in the same orbital are represented by two arrows poining in opposite directions Check all that apply. Watch the animation and idenify which of the following statements are correct The C atom has two unpaired electroes □ The He atom has two elections that have paralel spin in its 1s orbital □ The He atom has one electron each inis and 2sorbitals Electrons generally occupy the lowest energy orbital first O Type here to search 畢 /24/201

Answer 1

C-Electrons are 6 so Electrons configuration-1s^2 2s^2 2p^2 so it has 2-unpaired electrons Li-3 1s^2 2s^1 in any atoms 3s, 3p & 3d orbitals has different energies 3s < 3p < 3d (energy order) He-2 1s^2 two electrons are opposite (direction) spins 2 s is empty orbital Electrons generally occupies lowest energy orbital first Last one is true so options: 1, 2, 3, & 4 are correct
