Write a reflection on lesson 2.
We understand that matter consists of small and discrete particles. The matter is made up of atoms, ions, and molecules. Atom is the smallest part of an element thus, it is indestructible. It is called an ion if an atom has a charge. And a group of two or more atoms is called a molecule.
The Law of conservation of mass states that in any chemical change, the mass is conserved. Meaning that the total amount of mass of the reactants is equal to the total amount of the resulting product. For example, if you start with 5 grams of hydrogen and 5 grams of oxygen gas, the product will be the same which is 10 grams of water.
Meanwhile, the law of definite proportion and the law of multiple proportions is "That the ratio of elements in a compound is fixed" as said by Joseph Proust. These concepts tell us that whenever you make a compound with particular elements, the ratio you are going to use in those elements is the same throughout.
We realized that the size of every particle is approximately ten to the negative seventh power. I also realized that most elements are made up of a group of atoms. There are several elements that consist of only one atom; they are helium, xenon, neon, argon, krypton, and radon.
There are types of bonds in compounds. They are covalent bonds, ionic bonds, metallic bonds, and James Bond. (Haha! Just kidding) Covalent bonds are when two non-metallic elements bond together. In the case of an ionic bond, you form a compound using a metallic element and a non-metallic element. And lastly, the obvious one, the metallic bond is when two metallic element bonds together.
We hope you learned something from this post. Stay tuned for more information brought to you by Group Silver!
