Which statement is correct about an element’s identifying spectrum?

Atomic line spectra are a series of colored lines that are revealed when the atom is brought to a relaxed state from an excited state.

The colored lines occur due to the fact that electrons give off energy in the form of photons when moving from higher to lower energy level. These photons are in the visible light range and are seen as colors. The line spectra are unique to the element because each element has its own electronic configuration, since it has its own number of electrons.

Mass is the amount of matter in an object.  weight is the measurement of the pull of gravity on an object.  say for example, you travel to the moon which has a different gravitational field compared to the gravitational field of earth. (gravitational fields: earth = 1, moon = 0.165)  now when you are on the moon, the pull of gravity on you is different than on the earth. and as weight is the measurement of the pull of gravity on an object, that means yes, your weight can and will change on the moon.  however, on the moon, on earth or even on jupiter, the amount of mass inside of you remains the same. meaning your physical mass remains constant.  in conclusion it is possible for your weight to change as your mass remains constant.
