1. sep construct an explanation how do different elements and compounds produce the colors of fireworks?

Explanation:

Step1: Recall atomic structure concept

Atoms have electrons in different energy - levels.

Step2: Understand energy absorption and emission

When fireworks are ignited, elements and compounds absorb energy. Electrons jump to higher energy - levels. When they return to lower energy - levels, they emit light.

Step3: Relate emitted light to color

The energy of the emitted light corresponds to a specific wavelength, which we perceive as color. Different elements and compounds have characteristic energy - level transitions, resulting in different colors. For example, sodium compounds produce yellow light, strontium compounds produce red light.

Answer:

When fireworks are ignited, elements and compounds absorb energy, causing electrons to move to higher energy - levels. As electrons return to lower energy - levels, they emit light. The specific energy of the emitted light (corresponding to a particular wavelength and color) is determined by the characteristic energy - level transitions of the elements and compounds present in the fireworks.
