What happens when an electron emits a photon?
When an electron absorbs a photon, the energy it gains can cause it to change orbitals. The result is ionization. The electron can then emit a photon in the process of "falling back" into its original orbit. Note that electrons won't absorb a photon that cannot give them enough energy to reach a higher orbital. There are no "half measures" in this aspect of quantum mechanics as electrons cannot be shifted "half way" to the next higher orbital. The proof of the pudding here is that we can use lasers of a given frequency to stimulate the electrons in orbit around given atoms. By knowing how much energy a certain electron needs to move to the next higher orbital, we can tune our laser to that photonic energy. Then when we point our laser at a bunch of these atoms, we'll see a bunch of electrons being kicked up to higher orbitals and then emitting photons to return to their previous orbital. There is a bit more to this, but the essentials are here, and are a first step to understanding the subtle ways photons and electrons interact.
Is photoelectric effect an inelastic collision?
No, the photoelectric effect is not an inelastic collision. It is a process in which electrons are ejected from a material when it absorbs photons with enough energy to release the electrons. In an inelastic collision, kinetic energy is not conserved.
What determines if electrons are ejected from the surface?
The ejection of electrons from a surface is determined by the energy of the incoming photons or particles. If the energy is high enough, it can overcome the binding energy of the electrons in the material, causing them to be ejected.
What kinetic energy must the electrons have in order to exhibit a specific behavior?
The electrons must have enough kinetic energy to overcome the potential energy barrier in order to exhibit the specific behavior.
What are 3 terms to describe the location of electrons?
Random Orbital Unknown Electrons are thought to be found randomly within cloud-like orbitals around each atoms' nucleus, but it is physically impossible to ever know the precise location of an electron, for even if you were to look at them through a high-powered microscope, that small portion of light would be enough energy to change their location and path of movement.
When an electron in the ground state absorbs energy what happens?
jumps to the a higher orbital. This is only possible if the energy it absorbed is large enough to let it jump the gap. If the energy is not large enough for the electron to jump that gap, the electron is forbidden to absorb any of that energy.
Why would extreme heat knock electrons off atoms?
my best guess is that its absorbing enough energy to move it up to the next energy level and when it absorbs enough its far enough away to not be attracted anymore
What do you mean by the orbitals of lower energy are filled in first with the electron and only then the orbitals of high energy are filled?
Because the electrons have a negative charge and the nucleus has a positive charge, so they attract each other. The electrons stay in the orbital closest to the nucleus unless it is full or they have enough energy to move away from the nucleus.
What does liquid become when it absorbs enough energy?
It becomes a gas/vapor.
When a liquid absorbs enough energy it becomes a what?
It becomes a gas/vapor.
What is a d orbital?
A d orbital is a type of atomic orbital that can hold a maximum of 10 electrons. It has complicated shapes and is found in the third electron shell and higher, typically in transition metals and lanthanides. d orbitals contribute to the variety of chemical properties exhibited by these elements.

What is needed to launch anything into space?
Energy enough to accelerate the object to an orbital velocity.
What rapidly changes to a gas when it absorbs enough energy to reach the boiling point?
Liquid does this.
What determines if electrons are ejected from the surface?
The ejection of electrons from a surface is determined by the energy of the incoming photons or particles. If the energy is high enough, it can overcome the binding energy of the electrons in the material, causing them to be ejected.
When a liquid absorbs enough energy it becomes gas?
When a liquid absorbs enough energy, its molecules gain sufficient kinetic energy to overcome the attractive forces holding them together, causing them to break free and enter the gas phase. This process is called vaporization or evaporation, leading to the transformation of the liquid into a gas.
