3 days ago · Figure 4.2.1 4.2. 1: A Plot of Periodic Variation of Atomic Radius with Atomic Number for the First Six Rows of the Periodic Table. The melting point is a metric of the energy required to transform the solid phase of a substance into a liquid. Generally, the stronger the bond between the atoms of an element, the more energy required to break ...
- 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.
The periodic table organizes elements into groups and periods based on their chemical and physical properties. Elements in the same group share similar characteristics, like reactivity. The table is divided into metals, nonmetals, and metalloids, each with distinct properties.

Jul 23, 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.

Jun 23, 2021 · 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. Element atomic number increases as you move down a group from top to bottom or across a period from left to right.
On the periodic table, there are families which are groups of elements with similar properties. These families are alkali metals, alkaline earth metals, transition metals, post-transition metals, metalloids, halogens, noble metals, and noble gases.
