Electronegativity and element identification

Click For Summary
SUMMARY

The discussion centers on identifying an element from a gas pocket discovered on one of Jupiter's moons, using Mulliken electronegativity values and specific ionization energy and electron affinity data. The element in question has an ionization energy of 1527 KJ/mol and an electron affinity of 33 KJ/mol. Based on the provided electronegativity values, the element is identified as Oxygen (O), which aligns with the given ionization energy and electron affinity. Participants emphasize the importance of using appropriate forums for chemistry-related queries.

As part of the exploration of one of the moons of Jupiter, a probe digs under the surface, where it finds a pocket of gas. It starts to do some on-board experimentation. The data stored in the probe's computer include the following table of Mulliken electronegativity values of gases.

Element Electronegativity,x
(KJ/mol)

He 1178
Ne 1030
Ar 746
O 728
N 701
Kr 659
Xe 568
Rn 500


After doing some analysis, the probe determines that the gas pocket contains an element that has an ionization energy of I=1527 KJ/mol and an electron affinity of EA=33KJ/mol. What is the identity of this element?
Express your answer using the symbol for the element (e.g., Hg).


The book I have doesn't offer any help with this problem, if someone could help me i would greatly appreciate it

This seems very much an homework.

What are the 3 definitions you may need in order to solve this problem. If they are not in your book, can you find them on the internet?

PS: Next time round, use the Homework Forums (other sciences) for help with chemistry problems. This thread will be moved there by an Mentor.
