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.

Groups are the vertical columns on the periodic table. There are total 18 vertical columns on periodic table. Hence there are 18 groups. The elements lying in the same groups show similar chemical properties and they also have same number of valence electrons. For example; Example of group 1 All the elements of group 1 are highly reactive to water....

Sep 20, 2024 · Periodic table, in chemistry, the organized array of all the chemical elements in order of increasing atomic number. When the elements are thus arranged, there is a recurring pattern called the ‘periodic law’ in their properties, in which elements in the same column (group) have similar properties.
- The periodic table is a tabular array of the chemical elements organized by atomic number, from the element with the lowest atomic number, hydrogen...
- The groups of the periodic table are displayed as vertical columns numbered from 1 to 18. The elements in a group have very similar chemical proper...
- The arrangement of the elements in the periodic table comes from the electronic configuration of the elements. Because of the Pauli exclusion princ...
- The periodic table has two rows at the bottom that are usually split out from the main body of the table. These rows contain elements in the lantha...
- Alkali Metals. The alkali metals are all elements of Group I except hydrogen. These elements have one valence electron. They are highly reactive and can burst into flames when exposed to air.
- Alkaline Earth Metals. The alkaline earth metals are located in Group 2 of the periodic table, from beryllium (Be) to radium (Ra). They have two electrons in their outermost shell and are the second most reactive after alkali metals.
- Transition Metals. The transition metals lie from Group 3 to Group 12. They have more than one oxidation state, meaning they can have many oxidation numbers.
- Post-Transition Metals. The post-transition metals are located in between transition metals and the metalloids. They span from Groups 13 to 16. They have some characteristics of transition metals but are soft and conduct more poorly than transition metals.

Jun 23, 2021 · Groups and periods organize elements on the periodic table of the elements. A group is a vertical column down the periodic table, while a period is a horizontal row across the table. Both groups and periods reflect the organization of electrons in atoms.
