What do you Know About Atoms and Molecules
by Tilda Monroe
Review by Na'Daisa
What are atoms? Atoms are so tiny that they can't be seen. Atoms have other parts called molecules. Molecules are also tiny. Even though atoms are tiny, they have even smaller parts. There are three main kind of parts, electrons, protons and neutrons. Protons and neutrons are always in the center of an atom. When they are in the center, it is called the nucleus.
Electrons never stop moving because they're busy. An atom's electrons orbit the nucleus. All atoms have the same basic parts. Atoms with different numbers of protons are different. Atoms can also be called elements. Examples of elements are silver, gold, and oxygen. The periodic table is where you can find elements. The chart includes the element's atomic number and tell how many protons and electrons it has. Electrons are negative (-), protons are positive (+) and neutrons are neutral, meaning they have no charge.
Atoms are not always balanced. Sometimes an atom loses an electron. If an atom gains an electron it has a negative charge. Atoms can join together. Whey they join together, their forming a bond. A bond forms when two atoms share electrons from each other.
Two kinds of bonds are covalent and ionic. Covalent bonds happen when two atoms share electrons and ionic bonds form when one atom gives up. Atoms bonded together are molecules.
I recommend this book for everyone. I liked the book because I learned more about atoms.
I didn't know much about molecules...until now! Thanks and well done! -Akiera
ReplyDeleteReading this review makes me remember when we first started learning about this in school, especially when it was discussed last year in science class.

Latricia:Well,I know alot about molecules and atoms and you just told me more about them.
ReplyDeleteNadasia: I like this book because it tells me so much about atoms I didn't learn about yet.
