Allotropes

The video explains how the same atoms can have different properties when arranged differently. It uses carbon as an example, highlighting its four natural allotropes, including graphite and diamond, which have distinct characteristics due to their atomic arrangements.

What can cause the same atoms to have different properties?

• Different temperatures

• Different colors

• Different arrangements

• Different physical states

How can the properties of an element change?

• By changing its atomic number

• By changing its color

• By rearranging its atoms

• By altering its atomic mass
