what the hell is schrodinger model of atom electronic configuration?

Question

I'm in year 11, studying this subject and I'm gonna fail because I just don't get it..What the hell is schrodinger talking about S, p d subshells and how to fill...Can someone explain this to me in laymen's language...I would really appreciate it ta

Answer 1

There is no such thing as a "layman's" explanation of Schrodinger. You have to go to your text and go through the history of our understanding of electrons and the atom line by line. That will give you a good beginning. Don't expect to find any explanation that is a few lines or sentences long. That won't work. You have to go through the whole idea from scratch and understand it at every level. Check the electron configurations of 15 or 20 elements as a starting point. But if you still don't get it, go through all the elements starting with Hydrogen and working out the electron arrangement for each one until it becomes clear.

Dont try to take a shortcut, you will only succeed in keeping yourself confused.

Answer 2

As you go up the periodic table electrons in atoms are added in a fixed order. The result is that the outermost shell has 8 electrons in the outermost orbit.

(The exception here is He which only has 2).

The shells have a sub structure. The 1at does not have a sub structure. The 2nd. has 2 sub shells. the 3rd. has 3 sub shells etc.

For historical reasons the sub shells are called s, p, d, f.

Electrons fill the atom in the lowest shell/sub shell first.
The order is 1s, 2s, 2p. 3s, 3p, 4s.
