Alótropos

The video explains how the same number of atoms in the same physical state can have different properties when arranged differently. It highlights the example of carbon, which has four natural allotropes, including graphite, which is soft, and diamond, which is extremely hard.

What does it mean when atoms are in the same physical state but arranged differently?

• They are in a liquid state.

• They can have different properties.

• They are in different elements.

• They have the same properties.

How can the arrangement of atoms affect an element?

• It changes the element's atomic number.

• It changes the element's color.

• It makes the element heavier.

• It alters the element's properties.

Which of the following is a natural allotrope of carbon?

• Graphite

• Sulfur

• Silicon

What is a characteristic of graphite?

• It is extremely hard.

• It is transparent.

• It is soft.

• It is a liquid.

Which allotrope of carbon is known for its hardness?

• Fullerene

• Graphite

• Charcoal

• Diamond
