Neon

Postby Anokhi Patel 2B » Mon Oct 21, 2019 3:55 pm

When professor Lavelle was demonstrating isoelectronic atoms, through Na+, Mg2+, and F-, what was the significance of the element Neon?

Thank you

All of these ions were isoelectronic - they all had the same number of electrons. In this case, Na+, Mg2+, and F- all had the same number of electrons as the element Neon.

isoelectronic atoms have the same number of electrons. Na+, Mg2+, and F-, O2- and Ne all have 10 electrons which means they are isoelectronic, though they do not have the same chemical properties due to varying nuclear charges.

He could have used any element, not just Neon, as an example. Neon is a noble gas and has a full electron shell so it is stable without any charge. I think it was just easiest to show that the listed ions are isoelectronic with Neon because it is already stable. But you could say the same for Cl- and S2- for example.
