Any chemical element that is an effective conductor of electricity and heat can be defined as a metal. A metal is also good at forming bonds and cations with non-metals. Atoms inside of a metal quickly lose electrons in order to make positive ions or cations. The ions in turn are surrounded by the electrons that are delocalized, which give the metal its electric conductivity.

Alkali metals are a group of metals that you can find on the periodic table, known as the Group 1 elements. Members of the alkali metals include potassium, sodium, lithium, caesium, rubidium, and then francium. One element, hydrogen, that is usually a member of this group of metals frequently does not exhibit behavior that is comparable to the rest of the alkali metals. For the rest of the alkali metals, they display one of the best instances of group trends in properties among elements on the periodic table.

Alkaline earth metals belong to Group 2 elements of the periodic table and are made up of radium, barium, strontium, calcium, magnesium, and beryllium. The name for this specific group of metals comes from their own oxides that, in turn, provide the basic alkaline solutions. Aside from magnesium and beryllium, the alkaline earth metals possess an identifiable flame color. These flame colors are crimson red for radium, green for Barium, bright red for strontium, and orange for calcium.

Lanthanides are the 15 elements that comprise the atomic numbers 57 to 71 on the periodic table. The series of elements ranges from lanthanum to lutetium. All lanthanide elements are f-block elements, which means they correlate to the 4f electron shell’s filling. Even though the element called lutetium is a d-block element, it is mostly considered a d-block element, too. The group of elements as a whole is called lanthanide because the more light elements in their series are similar, chemically, to lanthanum.

Actinides are the 15 chemical elements that feature the numbers 89 to 103, which correspond to actinium to lawrencium. The name of this series of elements comes from the element actinium. While the majority of actinide elements are synthetic elements, uranium and thorium can be found in nature in more than just trace quantities. One property that these elements are famous for is the radioactivity that is found in all of them; plutonium, thorium, and uranium are utilized in nuclear weapons and reactors.

Transition metals are the elements that feature atoms that have an incomplete d sub-shell. Transition metals or elements are unique from other elements by their common properties. One property is that they form a lot of compounds in quite a few states of oxidation. Another property they are known for is their tendency to form a lot of paramagnetic compounds, mainly due to the low reactivity of their d electrons that are unpaired.

Metalloids are chemical elements that are best defined by two criteria. They often create amphoteric oxides and behave in the same manner as semiconductors. Silicon, boron, germanium, tellurium, antimony, and arsenic are in general classified as metalloids. Sometimes, the element called polonium is also included in the metalloid classification, but there is still dispute regarding this among the experts.

Other metals, or post-transition metals, are the group of elements on the periodic table that are situated to the right of the transition elements. Up to this day, what elements ought to be included in this group is hugely disputed. Usually, zinc, gallium, cadmium, indium, tin, mercury, thallium, lead, and bismuth are included as the other metals of the periodic table. With varying consistency, mercury, cadmium, and zinc (the so-called group 12 elements) are both included as well as excluded from lists of these other metals.
