Chemistry in the World

Chemistry

To begin this lesson. Chemistry is the scientific discipline involved with elements and compounds composed of atoms, molecules and ions: their composition, structure, properties, behavior and the changes they undergo during a reaction with other substances.

Some chemistry you might know of is:

• Carbon

• Hydrogen

• Oxygen

• Copper

• Potassium

Chemical Safety

Of course, there is safety within using chemicals. You might get sick or maybe even worse. You should wear protective gear on you. Like goggles, or a mask. But I reccomend Wear both!

Periodic table

You must've heard of this before. The periodic table, also known as the periodic table of elements, is a tabular display of the chemical elements, which are arranged by atomic number, electron configuration, and recurring chemical properties. The structure of the table shows periodic trends. The seven rows of the table, called periods, generally have metals on the left and nonmetals on the right!

Hydrogen

Seriously we can't live without it! It's 1st on the table. Mix this with Oxygen and we get Water! Which we also can't live without.

Study The Table!

We're going to take a quiz on it. (Don't worry. It will also be in the quiz whenever you feel like yo forgot.
