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.
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.
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.
Is Ionizing radiation powerful enough to strip electrons off of molecules forming ions?
Yes, ionizing radiation is powerful enough to remove electrons from atoms or molecules, resulting in the formation of ions. This process can lead to chemical changes in the substance being irradiated.
Why are the electrons in the atoms of insulator hard to knock off?
Let's take silicon dioxide, a simple constituent of glass and an insulator, and see why. SiO2 ===== The oxygen in this molecule is an electron hog with a electronegativity rating of 3.5. Not too many electrons escape the pull of oxygen.
Explain how copper atoms are converted into copper plus ions in a mass spectrometer?
In a mass spectrometer, copper atoms are converted into copper ions by first ionizing them. This is typically done by bombarding the atoms with high-energy electrons, which knock off one or more electrons from the outer shell of the atom, resulting in positively charged ions. These ions can then be accelerated and separated based on their mass-to-charge ratio in the mass spectrometer for analysis.

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.

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.
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 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.
Is Ionizing radiation powerful enough to strip electrons off of molecules forming ions?
Yes, ionizing radiation is powerful enough to remove electrons from atoms or molecules, resulting in the formation of ions. This process can lead to chemical changes in the substance being irradiated.
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 would exetreme heat knock electrons off atoms?
Heat is a form of energy that can be absorbed by electrons, which use the extra energy to move into higher energy orbits. If they absorb enough energy, they can escape the nucleus completely. A hot gas whose electrons have been stripped off is referred to as "plasma," and a great example is a simple flame.
