Which statement below describes an atomic emission spectra?

a) a diagram that shows the energies of molecular orbitals.

b) a spectrum that contains radiation distributed over all wavelengths.

c) the arrangement of electrons in the orbitals of an atom or molecule.

d) a series of colored lines that correspond to photons of specific energies emitted by a heated element.

ANSWER- B

Atomic emission spectra are produced when excited electrons return to the ground state. The emitted light corresponds to energies of the specific electrons.

in cartography, a contour line (often just called a "contour") joins points of equal elevation (height) above a given level, such as mean sea level. a contour map is a map illustrated with contour lines, for example a topographic map, which thus shows valleys and hills, and the steepness or gentleness of slopes.
