There are four main groups of elements in the periodic table: main group metals, non-metals, metalloids, and transition metals (See types of elements). There are 4 blocks in the periodic table. The blocks are: s-block.

The boron group are the chemical elements in group 13 of the periodic table, comprising boron (B), aluminium (Al), gallium (Ga), indium (In), thallium (Tl), and perhaps also the chemically uncharacterized nihonium (Nh). The elements in the boron group are characterized by having three valence electrons.

These are transitional metals, which have special circumstances. Following this rule: Elements in group 1 have one valence electron; elements in group 2 have two valence electrons; elements in group 13 have three valence electrons; elements in group 14 have four valence electrons; and so forth up to group 18.
333516
Elements in group 1 and group 2 are metals. Atoms of group 1 elements have one electron in their outer shell, and atoms of group 2 elements have two electrons in their outer shell. Some elements in groups 6 and 7, and all in group 0 (also known as group 8) are non-metals.

The elements in a group have similarities in the electronic configuration of their atoms, and thus they exhibit somewhat related physical and chemical properties. The periodic table has eight main groups: 1, 2, 13, 14, 15, 16, 17, and 18 (previously numbered Ia, IIa, IIIa, IVa, Va, VIa, VIIa, and 0, respectively).

Since 2016, the periodic table has 118 confirmed elements, from element 1 (hydrogen) to 118 (oganesson). Elements 113, 115, 117 and 118, the most recent discoveries, were officially confirmed by the International Union of Pure and Applied Chemistry (IUPAC) in December 2015.

['The elements are arranged based on their increasing atomic number.', 'There are 7 periods and 18 groups in the table.', 'The inert gases i.e. He, Ne, Ar, etc. ... ', 'All the groups are divided into sub groups A and B except 0 and VIII group in the modern periodic table.']

Group 13: Boron Group Boron is also the only metalloid in this group. ... Group 13 elements have three valence electrons and are fairly reactive. All of them are solids at room temperature. Boron is a very hard, black metalloid with a high melting point.
1350402
All of the Group 18 elements of the periodic table. Nonmetals that are in group 17 in the periodic table and if an element has 7 valence electrons it either as to gain or share 1 electron. Very reactive.

The first element in the group is the nonmetal nitrogen (N), followed by phosphorus (P), another nonmetal. Arsenic (As) (Figure below) and antimony (Sb) are the metalloids in this group, and bismuth (Bi) is a metal. All group 15 elements have five valence electrons, but they vary in their reactivity.
