A polynomial of degree zero is a constant term

The grouping method of factoring can still be used when only some of the terms share a common factor A True B False

The sum or difference of p and q is the of the x-term in the trinomial

A number a power of a variable or a product of the two is a monomial while a polynomial is the of monomials

When an electron in an atom changes energy states it emits a photon If the photon has a frequency of 6 x 1014 Hz how did the energy of the electron change?

The electron lost 4 x 10-19 J of energy.


If the photon has a frequency of 6 x 10 to the 14 Hz how did the energy of the electron change?

If the change in energy of electron is totally exhibited as a photon then the energy = h times frequency. h = 6.626 x 10 to -34 J s Simply multiply h and frequency you would get the energy in joule

The energy of a photon whose frequency is 5.8 x 1014 Hz is: 2.4322643592E-11 electron volts.


The frequency of a light wave is determined by the?

The light photon (light wave) was emitted by an electron jumping between two energy levels in an atom, the energy of the photon is determined by how large is the difference between these two levels, i.e the frequency of the photon is determined by the energy of the photon


What is the approximate energy of a photon having the frequency of 4.0 x 107Hz?

Photon energy = 1.77006248E-12 electron volts.


How is the energy released When an electron falls from a higher energy level to a lower energy level?

As a photon. The exact frequency (color) of the photon depends on the specific energy level.

The energy of a photon is directly proportional to its frequency.The energy of a photon is directly proportional to its frequency.The energy of a photon is directly proportional to its frequency.The energy of a photon is directly proportional to its frequency.


How does quantum mechanics differ from classical mechanics?

in quantum mechanism the energy of the photon electron vary with the frequency but independent of the intensity of the incident radiation while in classical mechanism the energy of the photon-electron should vary with intensity but should be independent of the frequency.


The change of an atom from excited state to ground state always involves what?

An atom emits a photon (particle of light) when transitioning from a ground state to its excited state. To obey conservation of energy, the energy gained by the atom when an electron moves to a lower energy level is equal to the energy it loses in emitting the photon. (The energy of a photon is E = hf, where E is the energy, h is Planck's constant, and f is the frequency of the photon.) Conversely, when an atom absorbs a photon (as is the case in absorption spectra), the electron absorbing the photon moves to a higher energy level.


How do electrons change when the sunlight excites them?

Depending on the energy (frequency) of the specific photon hitting the electron, one of three events happens: nothing, the electron is excited, or the electron leaves the atom. If the energy of the photon very high, the electron can absorb the energy and escape the nucleus' pull. This is called ionization. If the energy of the photon lines up with the energy spacing in the atoms energy levels, the electron will move to a higher energy state, becoming excited. The electron then returns to its original energy level, releasing the energy as light. If the energy of the photon does not fall into one of these categories, the electron does not interact with it. In terms of actually changing the electron, it only changes in energy, not any other property.

The photon energy is directly proportional to its frequency: Energy = Planck's constant * frequency.


What is energy of a photon emitted by an electron?

An electron emits a photon when it lowers its energy, going for a lower energy orbital. The energy of the photon will be the difference of energy between the orbital where the electron was, and the orbital where the electron went.

When an electron drops to a lower energy level what is the energy of the photon released?

The energy of the photon is the same as the energy lost by the electron


What is the relationship between the light emitted by an atom and the energies of the electron in the atom?

the frequency of a photon of light , the greater the greater the energy packed into that photon.


What is the threshold frequency of a metal?

The minimum amount of energy per photon necessary for that photon to knock an electron free from the crystal structure of that metal.


Is a photon is absorbed when an electron moves from a low energy level to a higher energy level?

Every element has a specific energy describing each of the energy levels that any given electron is able to occupy. In order to occupy a higher energy level the electron must gain some energy, and this energy is derived from a particle of light known as a photon. Since the electron can only exist in specific energy levels it must absorb a photon with the exact amount of energy required. A photon with too much or too little energy will have no effect. The amount of energy in a photon is proportional to the frequency of the light that it came from, so only certain frequencies of light can be used to move electrons from one energy level to another. Similarly, an electron would have to lose energy to drop to a lower energy level, and this energy is released in the form of a photon. If you know the difference in the energy levels, you can actually calculate the energy of such a photon and predict what frequency of light it will produce.

What happens when electrons change levels?

Energy is either absorbed or released. If the electron goes from a high energy orbital to a lower energy one, a photon is emitted. When a photon is absorbed, the electron goes from low energy to high.
