SSA Review (Properties of Matter: Big Idea 8)

Matthew has six cubes of different materials. Each cube has a mass of 10 grams (g). Matthew sorts the cubes into two groups using one physical property.

Which physical property did Matthew most likely use to sort the cubes into two groups?

• density

• magnetism

• melting point

• electrical conductivity

Lithium (Li), Sodium (Na), Potassium (K), Rubidium (Rb), Cesium (Cs), and Francium (Fr) are in the same column in the periodic table. Why are these elements in the same column in the periodic table?

• They have similar properties.

• They have atoms of the same size.

• They have the same number of protons.

• They have the same number of neutrons.
