Question

learning goal 1. describe physical changes in terms of the arrangement of particles and particles. o particles during a physical change by completing the sentences with the f tiny particles called atoms. in elements, such as carbon, oxygen, iron, or gold., atoms of different k/ps are bonded together ices.

Explanation:

Matter is made of tiny particles called atoms. Elements consist of one - type of atom. Compounds are formed when atoms of different types bond together. In physical changes, the particles (atoms or molecules) may change their arrangement (e.g., from solid to liquid, particles gain more freedom of movement), but the chemical identity of the particles remains the same.

Answer:

Matter is composed of tiny particles called atoms. In elements, all atoms are of the same type, such as carbon, oxygen, iron, or gold. In compounds, atoms of different types are bonded together. During a physical change, the chemical nature of the particles remains unchanged, but their arrangement may be altered. For example, in melting of ice (a physical change), water molecules change from a fixed, ordered arrangement in ice to a more random arrangement in liquid water, but they are still water molecules.
