Row of chemical elements
- In the periodic table of the elements, each numbered row is a period. A period on the periodic table is a row of chemical elements. All elements in a row have the same number of electron shells. Each next element in a period has one more proton and is less metallic than its predecessor.

Periods are the horizontal rows that show the number of electron shells, and groups are the vertical columns that show the number of valence electrons.
- 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.
May 28, 2024 · Learn how elements are organized into the periodic table based on their atomic number, period, and group. A period is a horizontal row of elements with increasing atomic number, and a group is a vertical column of elements with similar properties.
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.
