Atom

I apologize for these first two videos, the sound quality is absolutely hideous... ...as my usual camera and well sound equipment is currently in Dover (Dover, England). Ah well, here we are film #2...

n+l rule. So how do you remember this? Well, other than these subtle changes here out at the end, one of the important ways to remember this is what's called the n+l rule. And the n plus l...

All right. Today, in particular the second half of the lecture today, we're going to do some of the hardest concepts that we've done so far, and also some of the most important...

jbjb SPEAKER: In this film we shall be investigating the universe s smallest building block, the atom. The atom, which sometimes appears as the title of a rather boring subject in textbooks, actually...

In this screencast we are going to use the atomic species balances method to solve for a reaction. So we have a 100 moles of ethane, and they are sent to a reactor, and they react to form ethylene and...

southern most amazing thing u in one of the science publications they have taken affect the picture of a vibrating net actually atoms by breeding within a molecule doctor cuz been blogger is with us...

A normal atom has a neutral charge with an equal number of protons and electrons. For example, a neutral atom of sodium has eleven protons and eleven electrons. However, since atoms are more stable...

There are two types of covalent bonding - nonpolar and polar. Nonpolar bonding results when two identical non-metals equally share electrons between them. Diatomic molecules such as O₂ or I₂ form...

In a neutrally charged atom, the number of electrons is equal to the number of protons. Therefore, the negative charge of each electron is cancelled out by the positive charge on each proton. If the...

In this lab we will take a look at quantum systems. In these systems the total energy takes on discrete values that we describe with energy levels. Each level can be labeled with a quantum number n....
