What is the s group of the periodic table?
Understand the Problem
The question is asking for information regarding groups in the periodic table, specifically the 's' group. This involves understanding the organization of elements based on their electron configurations and similar chemical properties.
Answer
The s group includes Groups 1, 2, and helium.
The s group of the periodic table, also known as the s-block, includes elements from Groups 1 and 2, along with helium. These elements have their valence electrons in the s orbital.
Answer for screen readers
The s group of the periodic table, also known as the s-block, includes elements from Groups 1 and 2, along with helium. These elements have their valence electrons in the s orbital.
More Information
The s-block of the periodic table contains the alkali metals in Group 1 and the alkaline earth metals in Group 2. Helium is also part of this group because its electrons are in the s orbital.
Tips
A common mistake is to forget helium is part of the s-block due to its position in column 18.
