Exploring Metals and Nonmetals

What are some properties of metals?

• Metals have low melting and boiling points.

• Metals are conductive, malleable, ductile, lustrous, dense, and have high melting and boiling points.

• Metals are always brittle and break easily.

• Metals are non-conductive and insulators.

Can you name three nonmetals?

• Copper

• Oxygen, Nitrogen, Sulfur

• Gold

• Iron

What is a binary combination?

• A method of sorting binary data into groups.

• A combination of three or more elements.

• A selection or arrangement of two distinct elements, often represented as 0 and 1.

• A representation of numbers in decimal format.
