no, gamma rays are very high frequency electromagnetic radiation and are not protons or electrons as alpha and beta radiation are respectively.

How do positron emission and electron capture change an atom?
After positron emission or electron capture the atomic number is decreased with one.
What is proton or atomic number?
A proton is a subatomic particle in the nucleus of an atom. Protons have a positive electric charge. The atomic number of an element is equal to the number of protons in the nucleus of one of its atoms. Therefore, if you change the number of protons in an atom, you change the element.
What is the atomic number for the elements?
The Atmoic Number is the ;- #1 position in the periodic table. #2 the number of protons in the nucleus #3 the number of electrons around the nucleus for a neutrally charged atom.
What gives an element it's atomic number?
Atomic number is the number of protons (i.e. equal to the number of electrons) of an atom.
What does the atomic number indicate about an element?
The atomic number is the number of protons in the nucleus of one atom of the element.
The process of positron emission results in a change to the atomic nucleus. Is that change a decrease of 1 or a decrease of 2 or an increase of 1 or is there no change?
In positron emission, atomic number decreases by one. That's because a proton in the nucleus of the element that is about to undergo positron emission changes into a neutron. This is beta plus decay, by the way. You'll recall that the atomic number of an element, which is that element's chemical identity, is determined solely by the number of protons in the nucleus. If we "lose" a proton because it changes into a neutron, atomic number will now decrease by one. Check out the links below to related posts.
What happens to the atomic mass and number during gamma ray emission?
The atomic number and atomic mass number do not change as a result of gamma emission. That said, gamma emission is the result of the nucleus stabilizing itself from an excited state that was caused by some event, such as an alpha, beta, neutron, or some other kind of emission. As a result, when you look at the big picture, the atomic number and atomic mass number do change as a function of the event preceding the gamma event. The only time this is a distinct event is in the metastable nuclides, such as Tc-99m, where the gamma emission that follows the beta- emission does not immediately follow it - it can be delayed with a half-life of six hours.
What type of nuclear reaction results in a single nucleus undergoing a decrease in atomic number and the release of a helium nucleus?
This is emission of an alpha particle which is a helium nucleus. Thus the atomic number decreases by two and the atomic weight by four, in such a radioactive decay
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.
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 can the atomic number and what things can it identify?
The atomic number is the number of protons in the nucleus of an element. It is what determines what kind of an element it is. When you change the number of protons in the nucleus, you change the type of element.
What is the atomic number of the nucleus?
The atomic number is the number of protons in a nucleus.
What is the effect on the mass number and change of a nucleus when it loses alpha particles?
The mass number goes down by 4, and the atomic number goes down by 2 when a nucleus loses an alpha particle. XYZ --> alpha emission --> X-2Y-4Q + 24He2+
The beta emission process results in the daughter nucleus differing in what manner from the parent?
atomic number increases by one
What is The alpha emission process results in the daughter nucleus differing in what manner from the parent?
Atomic number increases by one.
How do positron emission and electron capture change an atom?
After positron emission or electron capture the atomic number is decreased with one.
Atomic number in the atomic nucleus?
The atomic number is equal to the number of the protons in the atomic nucleus.
