Gamma radiation and x radiation provide ionizing forms of radiation What effect does ionizing radiation have on molecules through which they pass?
"Ionizing" means that it can convert atoms and molecules into ions. In other words, it can knock off one or more electrons.
Describe how smoke detectors use alpha particles and what sets off the alarm?
Alpha particles constantly released by americium knock electrons off atoms in the air ionizing the oxygen, nitrogen atoms
How are electrons removed from atoms to form ions in a mass spectrometer?
The vaporised sample passes into the ionisation chamber. The electrically heated metal coil gives off electrons which are attracted to the electron trap which is a positively charged plate. The particles in the sample (atoms or molecules) are therefore bombarded with a stream of electrons, and some of the collisions are energetic enough to knock one or more electrons out of the sample particles to make positive ions. Most of the positive ions formed will carry a charge of +1 because it is much more difficult to remove further electrons from an already positive ion. These positive ions are persuaded out into the rest of the machine by the ion repeller which is another metal plate carrying a slight positive charge.
What is the electromagnetic radiation that rips electrons off of atoms to produce free radicals called?
Ultraviolet radiation can rip electrons off the atoms to produce free radicals. However radiations of higher frequency can also have the same effect. The higher the energy of the photon of the electromagnetic wave, the easier it is for the photon to knock off electrons from an atom.
Why do you keep giving electric shocks to people who you touch?
When you move in dry areas you knock off electrons and change your charge. If you knock off electrons then you go positive. If you gain electrons you go negative. When you touch something or someone that is grounded then the balance of electrons occurs. The transfer of the electrons quickly causes the shock.
What is Electron Bombardment?
Electron bombardment is a process where neutral atoms are converted to positive ions by bombarding them with electrons. Electrons are knocked off the atoms when fast moving electrons collide with them, forming positive ions.

"Ionizing" means that it can convert atoms and molecules into ions. In other words, it can knock off one or more electrons.
What happens to electrons in the photoelectric effect?
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.
What will happen if ions hits atoms at high speed?
When electrons hit atoms at high speed some of the electrons are knocked away or broken off of the atoms. Once this breakage happens after impact, the atom then becomes a positively charged ion.

Neutral atoms of the same element can differ in their number of what?
Neutrons. If the differ in electrons they are not neutral and if they differ in protons then they are no longer the same element as the number of protons determines the name of the element.
Why Radio waves and microwaves are non-ionizing radiation?
Because they don't have enough energy (or a short enough wavelength) to knock electrons off of atoms (ionization).
In the photoelectric effect what happened when light hits the metal?
electrons are knocked off atoms causing electricity to flow
What happens to electrons in photoelectric effect?
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.
What happens to electrons in the photoelectric effect (apex)?
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.
