Describe how light is emitted from an atom. A) As protons absorb energy they travel from the nucleus through the atom emitting l

ight along the way. B) The light is emitted when energy from sunlight is absorbed by the atom to excite a neutron into a higher level. C) When the nucleus absorbs sunlight, photons are energized and move to a higher energy level and are then released. D) Light is emitted from an atom as an electron falls from an excited state to the ground state releasing a photon.

Answer is: D) Light is emitted from an atom as an electron falls from an excited state to the ground state releasing a photon.

Electrons can jump from one energy level to another, absorbing or emitting electromagnetic radiation with a frequency ν (energy difference of the levels).

When electron jump from higher to lower energy level (shell), it emitting (releasing) energy.

For example, when the electron changes from n=4 (fouth shell) to n=2 (second shell), the photons are emitted.

Answer: Option D

Explanation:

The light is the visible spectrum which is seen by naked eyes. This can be a white light or some other color.

When energy is supplied to the atom, the electrons absorb energy and it tends to move from a lower energy level to a higher energy level.

When the electrons move from the excited state to the ground state, then it releases energy which is visible in the form of light.

This is how light is emitted from an atom.

Match each physical property of matter to the appropriate definition
Alekssandra [29.7K]

Physical properties of a substance include, solubility, boiling point, etc.

The correct matching of the physical properties with definition is as follows;

  • Solubility - the ability of a substance to dissolve  in another

  • Boiling point - the temperature at which a liquid  becomes a gas

  • Density - the amount of mass in a given volume

  • Buoyant force - the upward force on an object in a  fluid

  • Conductivity - the ability of a substance to transfer  heat or electricity

Above, all the physical properties have been properly matched with the corresponding definitions.

What are the two basic shapes of cnidarian? Give an example of each.
Aloiza [94]
Cnidarians have two body forms—polyp and medusa—which often occur within the life cycle of a single cnidarian. The body of a medusa, commonly called a jellyfish, usually has the shape of a bell or an umbrella, with tentacles hanging downward at the margin.

An example of the polyp form is found in the genus Hydra, whereas the most typical form of medusa is found in the group called the “sea jellies” (jellyfish). Polyp forms are sessile as adults, with a single opening (the mouth/anus) to the digestive cavity facing up with tentacles surrounding it.
