Longest Group in Periodic Table: A periodic table is used an important topic of understanding and significance. If you are a student or professional who needs to be aware of periodic tables, then it is also important that you are also aware of all the questions that are related with the periodic table and its understanding. In the era of internet where there are lot of concerns and doubts about periodic table, one such question that is often searched is “Which is the longest group in the periodic table”?
The Longest Group in Periodic Table
Firstly, it is important to understand that the periodic table is divided into 7 periods and 18 groups. The longest group in the periodic table is Group 1 (H, Li, Na, K, Rb, Cs, Fr). Alkali metals is the name from which the 1st group is known as in the periodic table.
Let’s have a look at the features of Group 1 – Alkali Metals:
- Alkali metals also known as Group 1 consists of elements that are known as Lithium (Li), Sodium (Na), Potassium (K), Rubidium (Rb), Caesium (Cs), and Francium (Fr).
- The reaction of all the elements from Group 1 with the water to form Alkalis has given them the name Alkali Metals.
- If kept at the standard temperature and pressure, the Alkali Metals are found to be all shiny, soft, and highly reactive and they also said to lose their outermost electron to form cations with charge +1. The number of valence electrons found are 1.
Understanding Group 1
Group 1 are also known as Alkali metals because of their reaction with the water to produce Alkaline solution.
