Indicate whether each of the following sstatements is true or false and explain your reasoning:
a. The photoelectron spectrum of Mg^2+ is expected to be identical to the photoelectron spectrum of Ne
b. The photoelectron spectrum of ^35Cl is identical to the photoelectron spectrum of ^37 Cl
Explain why more energy is required to remove an electron from the 1s orbital of Na (104 MJ/mol) than to remove an electron from the 1s orbital of Ne (84 MJ/mol)
(a) False
Since these 2 species are isoelectronic, same number of electrons, it would initially lead one to believe they would be the same. However, Mg has 12 protons, whereas Ne has 10, therefore there is a different level of interaction between the nucleus and the electrons. The photoelectron spectrum would be different.
(b) True
The photoelectron spectrum would be the same since the Zeff and number of electrons is the same.
Since, the effective nuclear charge in Na is higher than that of Ne.
