The correct answer would be the third option. The chemical properties cycle through each period because the atoms' outermost shells having two or more electron shells cannot have more than eight electrons. This is following the octet rule.
Answer:
Option B - Density increases
Explanation:
Density is defined as:
δ = mass / volume
When T°2 is > T°1, volume has been increased
As the volume increased, density has decreased.
↓δ = mass / volume ↑
In the situation above, temperature decreased from 4° to 0°.
The volume has been reduced, so the density has been increased.
↑ δ = mass / volume ↓
