ELI5: Explain Like I'm 5

Group 13

Okay kiddo, group 13 is a group of chemical elements that are found in the periodic table of elements. There are a total of 6 elements in this group: Boron (B), Aluminum (Al), Gallium (Ga), Indium (In), Thallium (Tl), and Nihonium (Nh).

These elements have some important things in common. One thing they have in common is the number of electrons they each have in their outermost energy level, which is three. This means that they all can form chemical compounds with other elements by sharing or taking electrons to complete that outermost energy level.

Another thing they have in common is their physical properties. They are all solid at room temperature except for gallium, which is a metal that can actually melt in your hand because it has a very low melting point. They are also good conductors of heat and electricity.

These elements are also important for different reasons. Boron is used to make cleaning products and fertilizers. Aluminum is often used to make cans and foil. Gallium is used in electronics, and thallium is sometimes used in medical tests.

So there you have it, group 13 is a group of 6 elements in the periodic table that have 3 electrons in their outermost energy level, which lets them form chemical compounds. They also have similar physical properties and are used for different important things like cleaning products, cans and foil, electronics, and medical tests.
