How many valence electrons are in group 1?
Understand the Problem
The question is asking about the number of valence electrons in group 1 of the periodic table, which contains the alkali metals. Each element in this group has one valence electron.
Answer
1 valence electron
The final answer is 1 valence electron.
Answer for screen readers
The final answer is 1 valence electron.
More Information
Group 1 contains the alkali metals, such as lithium, sodium, and potassium, which all have one valence electron. This single electron is what characterizes their chemical reactivity and makes them highly reactive, especially with water.
Tips
A common mistake is to confuse the number of valence electrons with the group number in the periodic table for higher groups (e.g., groups 10 or more). For group 1, however, the number of valence electrons straightforwardly matches the group number.
