Gamma Rays and X rays
An atom does not contain any cells. Atoms are the smallest units of matter and are composed of protons, neutrons, and electrons. Cells are the basic structural and functional units of living organisms.
The movement of electrons between atoms is called an electric current.
The outermost electrons in an atom that are responsible for all chemistry are known as valence electrons.
Molecules Atoms which are elements make up molecules. Protons and electrons make up atoms.
An atoms size is relative to the number of electrons an atom contains. Atoms with the least number of electrons are the smallest atoms. When atoms have the same number of electrons, the atom with the most protons will have the largest nuclear charge, and therefore be the smallest atom.

When ions collide with atoms, they transfer energy through collisions with the outer electrons of the atom. This transfer of energy can disrupt the balance of the electrons in the atom, causing an electron to be knocked off or ejected. This process is known as ionization and can result in the creation of new ions.
When you shine a certain level of light wavelength on metal, you can knock electrons off the atoms of the metal. This phenomenon was explained by Albert Einstein in 1905, for which he received a Nobel Prize in 1921.

An Alpha Particle is a fast, bare Helium nuclei composed of two protons, two neutrons, and no electrons, that is ejected at high velocity from a decaying nuclei. A Beta Particle is an electron or positron, ejected at extremely high velocity from a decaying nuclei. Both alpha particles and protons are Bosons. Both beta particles and electrons are Leptons. Their relationships are similar because the electron and proton are both components of atoms. The beta and alpha particles are both fragments ejected from decaying atoms.
In the photoelectric effect, photons eject electrons from a material's surface. The electrons gain kinetic energy and are emitted as photoelectrons. If the photon has sufficient energy (greater than the material's work function), the electron will be completely ejected from the material.
Photons of light (energy) are absorbed by the silicon atoms of the solar panel, resulting in an ejection of electrons proportional to the frequency of the photons absorbed. This is called the photoelectric effect. As a large number of electrons are being ejected from atoms and set into motion, this generates an electric current. It is this electric current that can be used to power devices.
No, the chlorine atoms do not return the electrons to the sodium atoms.
Electrons are smaller than atoms. There are electrons in atoms, but no atoms in electrons.
If monochromatic light is shining on an alkali metal and cesium is just above the threshold frequency, electrons in the cesium atoms will be ejected in a process called the photoelectric effect. These ejected electrons will have kinetic energy equal to the difference between the energy of the incident photon and the work function of the metal. The photoelectrons will be emitted instantaneously.
yes, some atoms don't actually have electrons.
Atoms share electrons when they form covalent bonds.
