Diagnostic of Science 8 3rd Quarter Quiz

Explain how the arrangement and motion of atoms and molecules contribute to physical changes.

• Physical changes are solely determined by external factors and not by the arrangement and motion of atoms and molecules

• The arrangement and motion of atoms and molecules only contribute to chemical changes and not physical changes

• The arrangement and motion of atoms and molecules have no effect on physical changes

• The arrangement and motion of atoms and molecules determine the physical state of matter and lead to physical changes.

What are the differences in the arrangement and motion of atoms and molecules in solids, liquids, and gases?

• The arrangement and motion of atoms and molecules differ in solids, liquids, and gases.

• The arrangement and motion of atoms and molecules are the same in solids, liquids, and gases.

• The arrangement and motion of atoms and molecules only differ in solids and liquids, not in gases.

• Solids have atoms that move freely, while liquids and gases have atoms that are tightly packed.

How does the particle nature of matter explain the behavior of solids, liquids, and gases?

• Solids, liquids, and gases have the same particle arrangement and movement.

• The behavior of solids, liquids, and gases is determined by their color.

• The particle nature of matter describes how particles are arranged and how they move in each state of matter.

• The particle nature of matter has no effect on the behavior of solids, liquids, and gases.

Explain how the periodic table can be used to determine the chemical behavior of an element.

• Elements in the same group have similar chemical properties, while elements in the same period have similar atomic structure and reactivity.

• Elements in the same group have similar atomic structure and reactivity, while elements in the same period have different chemical properties.

• Elements in the same group have similar chemical properties, while elements in the same period have different atomic structure and reactivity.

• Elements in the same group have different chemical properties, while elements in the same period have similar atomic structure and reactivity.
