Characteristics and Properties of Elements

The video tutorial covers the organization of the periodic table and the characteristics of metals, non-metals, and metalloids. It explains how the periodic table is organized by atomic number, groups, periods, and types of elements. The video also details the properties of metals, such as luster, malleability, ductility, and conductivity, and contrasts them with non-metals, which are dull, brittle, and good insulators. Metalloids, which have properties of both metals and non-metals, are also discussed, highlighting their use in electronics.

Which of the following is NOT a way the periodic table is organized?

• By increasing atomic number
