Good job
This is because, for the main reason that these elements that are mostly monatomic, are unreactive, they do not react, or in other words, exchange, and or share valence electrons through chemical bonds, as they already posses the maximum number of valence electrons in their valence shell, which is 8.
Answer: Hello, There! your answer is Below.
D. The formation of a solid from a liquid confirms that a physical
change took place.
Explanation:
The change from the liquid state to the solid state is called freezing. As the liquid cools, it loses thermal energy. As a result, its particles slow down and come closer together. Attractive forces begin to trap particles, and the crystals of a solid begin to form.
Hope this helps you!!!
Have a great day!!!
