In this book, we are going to cover the Periodic Table of Elements. We’re also going to take an in-depth look at Post- Transition Metals, Metalloids, and Nonmetals. So let’s dive right in!
WHAT IS THE PERIODIC TABLE OF ELEMENTS?
The Periodic Table is called “periodic” because its elements are organized in periods, also called cycles. The elements are organized in rows by their atomic number, which indicates the number of protons that each element has in its nucleus.
You’ll notice when you look at the Periodic Table that some columns are skipped. This is so that the elements that have valence electrons of exactly the same number align on the same columns.
Valence electrons are electrons that can create chemical bonds, so they are important to the element’s properties. Lined up in this way in columns, these elements have some properties that are similar. Each of the horizontal rows in the Periodic Table is called a period.
