The Periodic Table of the Elements Click to Begin

Let’s get started! Click below to learn more! Hello! My name is Dmitri Mendeleev! I created the first version of the periodic table of elements. Today I am going to explain how the periodic table is organized. Also, I will describe how you can determine the properties of individual elements and how they react with each other!

Organization NONMETALS METALS METALLOIDS Home Organization The table is divided into three different types of elements: metals, nonmetals, and metalloids. Metals are solids that make up a majority of the elements. They are shiny, malleable (can be rolled), ductile(can be drawn into wires), and good conductors. Nonmetals are not solid at room temperature. They are not shiny, malleable, ductile and they do not conduct electricity. Metalloids are the elements located between the metals and nonmetals. Therefore, they have properties of both types of elements. METALS METALLOIDS Home Organization Identification Oxidation State Ionic Bond Covalent Bond Self-Check

H Identification 1 1.01 Hydrogen Atomic Number Mass Number Name Symbol 1 1.01 H Hydrogen Atomic Number Specifies the number of protons in the nucleus. Mass Number The total number of protons and neutrons in the nucleus of an atom. Symbol The abbreviation for the element. Name The total number of protons and neutrons in the nucleus of an atom.

Oxidation State Home Organization Identification Oxidation State 1+ 4+ 4- 2+ 3+ 3- 2- 1- The oxidation state, also known as the oxidation number, is the charge on an atom. It can be determined for elements based on their position in the periodic table. Groups (columns) in the periodic table have similar properties and charges. For example: Group 1 is 1+, Group 2 is 2+, etc. One exception is Group 4. These elements can be 4+ or 4-. Home Organization Identification Oxidation State Ionic Bond Covalent Bond Self-Check

Na + Cl → NaCl Na + Cl → Na Cl Ionic Bond Na + Cl → NaCl An ionic bond occurs when one element gives its electrons to another element. This type of bond usually occurs between a metal and nonmetal. Na + Cl → Na Cl Home Organization Identification Oxidation State Ionic Bond Covalent Bond Self-Check

Cl + Cl → Cl2 Cl + Cl → Cl Cl Covalent Bond A covalent bond occurs when one element shares its electrons with another element. This type of bond usually occurs between two or more nonmetals. Cl + Cl → Cl Cl Home Organization Identification Oxidation State Ionic Bond Covalent Bond Self-Check
