SCH3U - Balancing Nuclear Reactions

When a chemist is working in a lab, their goal with atoms is to make them more

• stable

• friendly

• intelligent

• arrogant

Answer explanation

The question is about the goal in chemistry. The correct answer is 'stable'. In chemistry, reactions generally tend towards stability. That's why substances react with each other, to attain a more stable state. The options 'friendly', 'intelligent', and 'arrogant' do not describe goals in chemistry.
