Re: Lowest Energy

Is this related to ground state at all? Like would lowest energy mean the electrons are in ground state?

Electron Configuration

I am very confused about the s,p,d and f symbols and how to use them. I noticed there are numbers before and after these symbols and I realize that they represent the electron I just forgot how to interpret or form these configurations. I could really use the help.

With h/mv can't this also be expressed as h/p?

Re: Photoelectric Effect original purpose

The original purpose was to determine how much energy it would take to eject an electron from a specific metal

Re: 7th edition 1A.11

I am assuming either in lecture or in discussion we will learn it if we have to know it for the test but if it explains in in the text book you could read over it and take notes just in case.

Re: 7th edition 1B.5

KeV is Kiloelectron Volts so 10 to the third of standardized. Change this to regular electron Volts (eV) and you should be able to do your conversion.

Re: Measuring Wavelength

In class he said the minimum was 10 to the negative 18 and I do not think there is a maximum. He said when it gets so small it is just continuous and you cannot measure the wave length, I am sure this applies at some point when it gets too large but I do not think he mentioned this in lecture.

Exam and Homework Problems

I was wondering if our first test is during our discussion sections this coming week?
Also, is the homework for this coming week over fundamentals still or the new section?

Re: Atomic Weight vs Molecular Weight

The atomic Mass is the mass of one atom of an element
The Molecular weight is the mass of the sum of all the elements in a compound

Re: HW1 F19

Think of the total mass as 100 grams. Hydrogen would then be 5.19g of the 100g total, Nitrogen would be 28.85g of the total 100, Carbon would be 49.48g of the 100 and Oxygen would be 16.48g of the 100g. Then divide each element by it's molar mass. The element with the smallest answer is what you wil...
