Re: Radicals

Can someone explain why the more electronegative element gets the radical? In my mind, it would make more sense for the less electronegative one to have it.

Re: Ion formation vs molecule

To see if an ionic or covalent bond would from you should look at the difference in electronegativity between the two atoms involved in the bond. If the electronegativity difference is greater than than 2 then an ionic bond will form. If the electronegativity difference is less than 1.5 then a coval...

Re: Valence Electrons?

Could someone further clarify the answer to this question? I'm still confused about how to figure out the number of valence electrons for transition metals.

Re: ion charge

You should look at the number of valence electrons the element has based on its position in the periodic table. For example, sulfur has 6 valence electrons and so would gain 2 more electrons to have a full octet. Gaining 2 electrons would then make a -2 ion.

You would write out all the values like -2, -1, 0, 1, 2, because those are the values, not 5.

Re: Homework Help

You should also look at if the spins are all in the same direction for an orbital filled with just parallel electrons to make sure it is in the ground state.

Re: paired and parallel electrons

According to Hund's rule, every orbital must have one electron before each orbital has a pair of electrons. The number of electrons before you can start pairing depends on the orbital. For example, in a p subshell if there was only 3 electrons, they would all be parallel. However, if there was 4 ele...

Re: Spin up and spin down

An electron does not actually spin "up" or "down" these are just words we use to describe 2 different states.

Re: Which Element to Use in Electron Configurations

When writing out electron configurations out, there are 2 formats you can use. The first format is writing it all out, for example the electron configuration for lithium would be writing as 1s2 2s1. The second format is naming the past noble gas before the element and just writing the configuration ...
