Sapling question 24

Postby Chloe Shamtob 2H » Sun Nov 01, 2020 6:48 pm

Hi, can someone please explain what having a high effective nuclear charge means? Why do the 2p electrons in fluorine have a higher effective nuclear charge that the 2p electrons in oxygen?

Effective nuclear charge refers to the net positive charge an electron experiences in an atom. Since the only positive component of an atom of matter is a proton, and a fluorine atom would have 1 more proton than an oxygen atom, a fluorine atom would have more total positive charge to distribute amongst its electrons. This means that, even though the two electrons are in the same orbital, they will receive a different amount of charge from the nucleus.
I hope this helps! Lmk if you still have questions.

Hi,

Having a high effective nuclear charge signifies that the electrons are more attracted to the nucleus, resulting in a smaller atomic radius. The effective nuclear charge is the net positive charge from the nucleus on an electron. So, having a higher effective nuclear charge means the electrons are more greatly attracted to the nucleus. Fluorine has a greater nuclear charge in comparison to Oxygen because it possesses more protons, causing it to have a greater attraction for electrons at its nucleus. Hope this helps!

The fluorine atom has a higher number of protons in its nucleus (meaning there is a higher charge that attracts electrons). Because of this, the attraction would be higher :)
