Transition metals and their properties

Transition metals, found in the middle block of the periodic table, include iron, copper, and nickel. Unlike group 1 metals like sodium and potassium, transition metals have high melting points, low reactivity, and form brightly colored compounds. They are strong and hard, making them suitable for resisting environmental reactions. Transition metals can exist in multiple ionic forms, leading to a variety of colors in their compounds. For example, copper can form both copper I and copper II chloride, each with distinct colors. Manganese can form ions with charges ranging from +2 to +7, each showing different colors. The video concludes by summarizing the useful properties of transition metals.
