What radiation decreases the atomic number of the atom?
alpha
What are three common forms of atomic radiation?
alpha beta gamma
Which type of nuclear radiation (nuclear emission) has the greatest mass?
Alpha or an He nucleus because it has a mass of 4 when all the others have a mass of close to zero.
What are the 4 types of radiation and what does each type do to the nucleus?
Usually with the '4 types of radiation' it is referred to:- alpha radiation (emission of an alpha particle = a helium nucleus = 2 neutrons + 2 protons):Hence for the emitting nucleus the mass number decreases by 4 and the atomic number by 2.- beta-minus radiation (emission of a beta- particle = an electron)Hence for the emitting nucleus the mass number remains the same and the atomic number increases by 1 (a neutron decays into a proton and beta- radiation)- beta-plus radiation (emission of a beta+ particle = a positron)Hence for the emitting nucleus the mass number remains the same and the atomic number decreases by 1 (under the addition of energy a proton decays into a neutron and a positron)- gamma radiation (emission of high energetic photons)The emitting nucleus doesn't change its mass number and atomic number,but it jumps from a higher energy level to a lower energy level.
What happens to the atomic number when an isotope releases gamma radiation?
It depends on what caused the gamma event in the first place.Strictly speaking, gamma radiation is caused by the de-excitation of the nucleus, so the atomic number (and Atomic Mass) does not change during a gamma event.However, the gamma event is usually precipitated by some other event, such as a beta or alpha decay that does change the configuration of the nucleus. An alpha event reduces the atomic number by 2 (and reduces the atomic mass by 4), while the beta event increases the atomic number by 1 (and does not change the atomic mass very much).Its actually more complex than that, but the answer to the original question is that nothing really happens to the atomic number during a gamma event.

What do you call the type of radiation that is described as having a positive charge with an atomic mass of 4 making it a Helium atom without any electrons?
an alpha particle
Is alpha particle is heavy particle?
An alpha particle is a helium-4 nucleus. It has a mass of about 4 atomic mass units.
Mass of alpha particle?
The mass of an alpha particle is 4 atomic mass units, 2 protons and 2 neutrons, or about 6.644656 x 10-27 kg.
Which type of nuclear radiation (nuclear emission) has the greatest mass?
Alpha or an He nucleus because it has a mass of 4 when all the others have a mass of close to zero.
Which type of radiation alpha beta or gamma results in the greatest change in mass number?
alpha - 2 neutrons and 2 protons released or neutron collision with a fissionable nucleus resulting in the fissioning of the atom into two fission fragments and more neutrons creating two atoms each a little less than half the atomic mass of the original atom
An alpha has the same mass and atomic number as an?
A+. . .. . . . helium nucleus
What happens to the mass and atomic number when there is an alpha decay?
The mass decreases by 4 units and the atomic number by two units.

How is the atomic number changed by gamma decay?
There is no change in atomic number with the emission of gamma radiation. Unlike alpha or beta radiation, it does not have any kind of particles. It's emission results only when an excited nuclei goes to an unexcited state by emitting these.
