Answer:
N- 1s2 2s2 2p3
Mg- 1s2 2s2 2p6 3s2
O- 1s2 2s2 2p4
F- 1s2 2s2 2p5
Al-1s2 2s2 2p6 3s2 3p1
Explanation:
Order of decreasing atomic radius
Mg,Al, N,O,F
Order of increasing ionization energy
Mg,Al, N,O,F
Reason:
Atomic radius decreases with increase in nonmetallic character. Looking at the electronic configurations, as effective nuclear charge increases, the atom becomes smaller and the attractive force between the nucleus and the outermost electrons increases. Hence, the radius of the atom decreases and ionization energy increases. Note that the addition of more orbital electrons implies addition of more nuclear charge since the both must exactly balance for the atom to remain electrically neutral. The more the electrons in the outermost shell, the higher the first ionization energy.
"Sigma"s between the hydrogens and the oxygen
Hello. You did not say what is the experiment to which this question refers, which makes it impossible for it to be answered accurately.
However, advice that should be given to anyone who should start an experiment is: establish a control treatment, provide all treatments with the same variables and the same resources, write down everything that happened in the experiment from implementation to data collection and results, make measurements and analyzes on the same date in all treatments and keep the steaks in the same environment.
