Question

each emitted spectral line in an atomic spectrum represents a. a specific frequency of light emitted by an element. b. many colors of an element. c. a pattern characteristic of all the elements. d. all of them. question 7 when an atom is excited, its a. electrons are boosted to higher energy levels. b. atoms are charged with light energy. c. atoms are made to grow bigger. d. none of them.

Explanation:

For the first question, atomic spectral lines correspond to specific frequencies of light emitted by an element as electrons transition between energy levels. Each line is unique to the element's energy - level structure. For the second question, when an atom is excited, its electrons absorb energy and move to higher energy levels.

Answer:

A. a specific frequency of light emitted by an element.
A. electrons are boosted to higher energy levels.
