State one way in which Group 1 elements differ from other metals. State what happens to the boiling point as you move down Group 1. Name the gas produced when Group 1 elements react with water.
Understand the Problem
The question involves understanding the properties of Group 1 elements from the periodic table, particularly focusing on their boiling points and chemical reactions. The user needs to explain the patterns in boiling points as you move down the group and identify the gas produced when these elements react with water.
Answer
Group 1 metals have lower densities; boiling points decrease down the group; hydrogen gas is produced.
The final answer is: Group 1 elements differ by having lower densities than most other metals. The boiling point decreases as you move down Group 1. Hydrogen gas is produced when they react with water.
Answer for screen readers
The final answer is: Group 1 elements differ by having lower densities than most other metals. The boiling point decreases as you move down Group 1. Hydrogen gas is produced when they react with water.
More Information
Group 1 elements, known as alkali metals, are characterized by their high reactivity, especially with water, resulting in the formation of hydrogen gas and metal hydroxides.
Tips
Students may confuse melting and boiling points; both decrease down the group.
