This animation shows the structure of matter at smaller and smaller scales. Zooming into a human hair, we p**** through hair cells, fibril structures, keratin molecules, Carbon atoms, nuclei, neutrons, protons, and finally quarks.

Here's how to write formulas for binary ionic compounds. We'll see how you have to balance the charges of the two ions so they cancel each other out.

Equation balancing will make sense! Here, we will do a bunch of practice problems for balancing chemical equations. We'll see the process or trial and error and the steps that you have to go through to balance chemical equations. You start by keeping track of the number of atoms on both sides of the equation, and then you add coefficients to one or more of the elements and compounds to make the number of atoms equal.

How to balance chemical equations. We'll start out with examples that show the concepts behind balancing chemical equations. We will start with a word equation, and then write a chemical equations, and then visualize the atoms and molecules and how they change. To figure out if the equations is balanced, we look at the number and type of atoms on each side of the arrow. If the number and type of atom is not the same on both sides, the equation in unbalanced. We need to change the number of one or more of the compounds in order to get the atoms to balance. We do this by placing coefficients (numbers) in front of each of the compounds. When balancing equations, you cannot ever change the subscripts of a compound.

Mr. Andersen describes the major groups on the periodic table.

Hank gives us a tour of the most important table ever, including the life story of the obsessive man who championed it, Dmitri Mendeleev. The periodic table of elements is a concise, information-dense catalog of all of the different sorts of atoms in the universe, and it has a wealth of information to tell us if we can learn to read it.

How to memorize the periodic table 10X faster - Video 1. Start with the first 20 elements at https://www.memorize.academy/first-20-elements and then go for the entire periodic table of 118 elements at https://www.memorize.academy/m....emorize-the-periodic

How do you memorize the periodic table in the fastest and easiest way possible? You use the natural power of your visual memory.

We offer an easy way to memorize the periodic table. Memorization of the periodic table with our innovative animated video series takes just hours, so memorize the elements now!

Most people only know the typical techniques to memorize using your verbal memory – acronyms, acrostics, rhymes, ****ociations and songs. Those techniques can be great for remembering small amounts of information, but they don’t take advantage of the dramatic improvements to your recall when you activate your visual memory.

We’ll begin by picturing a typical poster or chart of the periodic table. There are many small, colorful squares, each with a name, number and symbol of an element, and together they create a large irregular shape.

This image will act as an anchor in your memory, holding down the chain of images which link together all the elements.

Now we’ll take that colorful poster and attach it to the first element. Picture that poster of the periodic table and imagine it’s wrapped around a water hydrant.

Why a water hydrant?

1. Hydrogen

The 1st element in the periodic table is Hydrogen. Hydrogen sounds similar to hydrant and that’s how you’ll be reminded of it. Picture a water hydrant you see on the sidewalk. It’s short, stubby, red, and looks strong. The hydrant is like a little man with a small hat on top and stubby arms sticking out the side.
Imagine that hydrant with the chart of the periodic table wrapped around it. When you think of the chart of the periodic table, you’ll picture it wrapped around a water hydrant. Because hydrant sounds similar to hydrogen, you’ll know the 1st element in the table is Hydrogen.

2. Helium

The 2nd element is Helium. If you’re like me, when you think of Helium, you automatically think of a helium balloon. When you let it go, it’s the type that floats up into the sky. Now imagine an enormous helium balloon. Make it the size of a car and picture it attached to the water hydrant. Because the helium balloon is so big and has so much lifting power, it starts to lift the water hydrant up off the sidewalk. Together they slowly float up into the air and away into the sky. Now, when you visualize the helium balloon floating upwards, you’ll know the 2nd element is Helium.

3. Lithium

The 3rd element is Lithium. Lithium sounds a bit like “lithp”. People that have a lisp – a type of speech impediment – aren’t able to pronounce “lisp” and say “lithp”. Let’s pretend the large helium balloon has a lisp. It also has a small hole in it, causing the balloon to slowly deflate. Usually a balloon with a hole in it will make a slow “ssss” sound, but because this balloon has a lisp or “lithp”, it makes a “thhh” sound. Visualize the large balloon slowly deflating making a “thhh” sound. When you think of the balloon’s “lithp”, you’ll be reminded of the 3rd element, Lithium.

4. Beryllium

The 4th element is Beryllium. If you say Beryllium slowly, it sounds like “bee really yum”. Picture your slowly deflating balloon. Imagine an enormous bumble bee lands on the balloon. The bee is the size of a football and has bright yellow and black stripes and buzzes loudly. The bee licks the balloon to have a taste and says, “that’s really yum!” It really likes the taste of the balloon. When you picture the bee licking the balloon, you’ll think, “bee really yum”, and be reminded of the 4th element, Beryllium.

5. Boron

The 5th element is Boron. We can break up the word Boron into “bore” and “on”. The word “bore” can mean to drill a hole. Picture now the bee, after tasting the balloon. It uses its stinger, pierces the balloon and starts to spin around in a drilling motion. The bee has landed on the balloon, tasted it, and now it’s started to “bore on” the balloon. When you picture the bee begin to bore on the balloon, you’ll remember the 5th element, Boron.

020 - Ionic Bonding

In this video Paul Andersen explains how ionic solids form when cations and anions are attracted. When atoms lose or gain electrons they form ions. The strength of the attraction between ions is based on the amount of charge and the distance between the ions.
