| The symbol B in the periodic table means boron. Boron is an element of group 13 whose properties place it on the border between metals and non-metals. It is a semiconductor and is chemically closer to silicon than aluminum, gallium, indium and thallium.
Calcium (Ca) belongs to group 2 because it contains two valence electrons. In the old IUPAC system, the letters A and B were displayed in the left (A) and right (B) parts of the table, while in the CAS system the letters A and B were displayed as the main elements of group (A) and. The transition elements (b) are shown.
Metals of group B. Metals of group B are called transition metals. You are at the center of the periodic table between Group IIA and Group IIIA. They provide a transition between basic sneakers on the left and acidic sneakers on the right.
New objects can be named after a mythological concept, a mineral, a place or country, a property or a scientist. The names should be unique and maintain historical and chemical consistency. No one has named an article yet, but many articles are named after prominent researchers.

Group 13 is sometimes called a citizen group, named after the first member of the family. Not surprisingly, these elements are found in column 13 of the periodic table. This group includes boron, aluminum, gallium, indium, thallium and ununtrium (B, Al, Ga, In, Tl or Uut).
Elements. The elements are classified according to their reactivity in the periodic table. The elements of group IA are called alkali metals. The elements of group IIA are called alkaline earth metals. Elements of group VIIA are called halogens, and elements of group VIIIA are called noble gases or inert gases.
The most beautiful elements of the periodic table
Sulfur is a chemical element represented by the chemical symbol S and the atomic number 16 on the periodic table. Selenium is a non-metal and can be chemically compared to its other Group 16 non-metallic counterparts: the oxygen family, such as sulfur and tellurium.
Fluorine (F) is the first element of the halogen group (group 17) of the periodic table. Its atomic number is 9 and its atomic weight is 19, and it is a gas at room temperature. It is the most electronegative element as it is the upper element of the halogen group and is therefore very reactive.
Lithium. Lithium is a member of the alkali metal group and is found just below hydrogen in the first column of the periodic table. Like all alkali metals, it has a single valence electron that readily forms a cation or compound. Lithium is a soft, silvery-white metal at room temperature.
Scheele called the element deflogistic hydrochloric acid; chlorine had been known for 33 years. In 1807, Humphry Davy studied chlorine and discovered that it was a real element.
Noble gas, some of the seven chemical elements that make up Group 18 (VIIIa) of the periodic table. The elements are helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), radon (Rn) and oganesson (Og).
Halogens are all elements of group 17 of the periodic table. Halogens include fluorine, chlorine, bromine, iodine and astate. All of these are considered non-reactive metals. Because these atoms are so close to a full set of eight valence electrons, they are very reactive.
