Explain the characteristics of the alkali metals in Group I, specifically lithium, sodium, and potassium, noting their softness and the general trends observed as you move down the group, which include: (a) a decrease in melting point (b) an increase in density (c) an increase in reactivity

Quick explanation

Explain the characteristics of the alkali metals in Group I, specifically lithium, sodium, and potassium, noting their softness and the general trends observed as you move down the group, which include: (a) a decrease in melting point (b) an increase in density (c) an increase in reactivity

• This point belongs to Group I properties, especially Group I properties outcomes.
• You need to be able to explain the characteristics of the alkali metals in Group I, specifically lithium, sodium, and potassium, noting their softness and the general trends observed as you move down the group, which include: (a) a decrease in melting point (b) an increase in density (c) an increase in reactivity.
• The key ideas to know are Describe, Explain, and Identify.
• Use the linked flashcards and practice questions to check recall, then practise applying the idea in an exam-style answer.
