In chemistry, a group (also known as a family) [1] is a column of elements in the periodic table of the chemical elements. There are 18 numbered groups in the periodic table; the 14 f-block columns, between groups 2 and 3, are not numbered.

23 cze 2021 · An element group is a vertical column on the periodic table. Atoms in a group share the same number of valence electrons. There are 18 element groups. An element period is a horizontal row on the periodic table. Atoms in a period have the same number of electron shells. There are 7 element periods. Element Groups
According to the IUPAC system of naming groups, there are 18 groups, with the group number ranging from 1 to 18. The elements in each group have the same number of valence electrons and hence, have similar chemical properties determined by the outermost electrons.
The periodic table, also known as the periodic table of the elements, is an ordered arrangement of the chemical elements into rows ("periods") and columns ("groups"). It is an icon of chemistry and is widely used in physics and other sciences.
5 dni temu · Periodic table - Elements, Groups, Blocks: The periodic table of the elements contains all of the chemical elements that have been discovered or made; they are arranged, in the order of their atomic numbers, in seven horizontal periods, with the lanthanoids (lanthanum, 57, to lutetium, 71) and the actinoids (actinium, 89, to lawrencium, 103) ...
10 gru 2023 · The periodic table is used as a predictive tool. It arranges of the elements in order of increasing atomic number. Elements that exhibit similar chemistry appear in vertical columns called groups (numbered 1–18 from left to right); the seven horizontal rows are called periods.
