On the periodic table the elements are called groups.
bi and po
Metal is located throughout the periodic table. The periodic table is based on atomic weight. Metals range from some of the lightest to the heaviest of elements.
There were around 52 known elements in the periodic table in 1834. The periodic table was still in its early stages of development during this time, and many elements were discovered and added to the table in the years that followed.
Julius Lothar Meyer was a contemporary of Mendeleev and like him and Newlands made contributions to the classification of elements in what we now call the periodic tabel.

They are organized by atomic number (the number of protons/electrons in the element).

Group 18.

Kepler was a mathematician, astronomer and astrologer. He did no work with the periodic tabel, which hadn't been discerned yet, at any rate - that was Mendeleev, some centuries later.
The periodic table is an arrangement of the elements by atomic number. It was made by Dmitri (Deh-Mee-Tri) Mendeleev (Men-Del-Leh-Av) The set-up and the specific details vary due to the different types of tables.
Halogens are the 17th group (column) on the periodic table. This is the most reactive non-metal group. The five halogens are:Fluorine (F)Chlorine (Cl)Bromine (Br)Iodine (I)Astatine (At)
The elements on the stairs of the periodic table are known as metalloids. These elements exhibit properties intermediate between metals and nonmetals, making them useful in various applications, such as semiconductors in electronics. Common metalloids include boron, silicon, germanium, arsenic, antimony, and tellurium. They are typically found along the zigzag line that separates metals and nonmetals on the periodic table.
