Question 1

_________ developed the model of the hydrogen atom using discrete orbits.&#10;A) Niels Bohr&#10;B) Wien&#10;C) Boltzman&#10;D) Newton

Accepted Answer

Niels Bohr developed the model of the hydrogen atom that introduced the concept of discrete orbits for electrons, which was a significant advancement in atomic physics.

Question 2

A spectrum with dark lines is called a(an)&#10;A) emission line spectrum.&#10;B) Bohr line spectrum.&#10;C) absorption line spectrum.&#10;D) continuous spectrum.

Accepted Answer

An absorption line spectrum is characterized by dark lines. These lines appear because the material between the source and the observer absorbs specific wavelengths of light, leaving dark lines in the spectrum.

Question 3

Very dense material when heated will give off a ____ spectrum.&#10;A) Kirchhoff&#10;B) emission&#10;C) absorption&#10;D) continuous

Accepted Answer

A very dense material when heated emits a continuous spectrum, which contains all wavelengths without any gaps.

Question 4

The spectrum of the Sun shows&#10;A) a continuous spectrum with no lines.&#10;B) a continuous spectrum with dark lines.&#10;C) a continuous spectrum with bright lines.&#10;D) a series of bright lines.

Accepted Answer

The spectrum of the Sun is a continuous spectrum with dark lines, known as absorption lines. These lines are caused by elements in the Sun's atmosphere absorbing specific wavelengths of light, resulting in dark lines in the otherwise continuous spectrum.

Question 5

__________ studied the basic forms of the spectrum in the 1800s.

Accepted Answer

The answer of __________ studied the basic forms of the...

Question 6

________ of atoms determine the colors the atom will absorb or emit.

Accepted Answer

The answer of ________ of atoms determine the colors the...

Question 7

An emission line spectrum is a few bright colored lines on a dark background.

Accepted Answer

An emission line spectrum is produced when atoms in a hot, thin gas emit light at specific wavelengths, creating bright lines against a dark background, corresponding to the energy differences between electron energy levels in the atom.

Question 8

A continuous spectrum is a few bright lines.

Accepted Answer

A continuous spectrum shows a seamless range of colors or wavelengths without any interruptions, unlike a few bright lines which would indicate an emission spectrum.
