What are two types of radioactive decay?
The two types of radioactive decay are alpha and beta. Generally, in alpha decay the nucleus will lose 2 protons and 2 neutrons (it's a helium nucleus). Beta decay involves a neutron losing an electron and becoming a proton, so the atomic mass remains the same, but the atomic number increases by one since there is another proton.
Do element identities reamin the same or change during nuclear decay?
That depends on the nuclear decay type. For gamma decay, the identity does NOT change, but for alpha and beta, it does.
Can alpha and beta decay the parent element and the daughter element can be different isotopes of the same elements?
False.
How is the atomic number of a nucleus change is it by alpha decay or beta decay or gamma decay?
Alpha decay decreases the atomic number by two. Beta- decay increases the atomic number by one. Beta+ decay decreases the atomic number by one. Gamma decay does not change the atomic number. However, gamma decay is often incidental to a precipitating alpha or beta event that upsets the energy equilibrium in the nucleus, so the two are not unrelated.
Are beta emission and beta decay the same?
There is a difference between beta emitters and beta particles. In situations where an atomic nucleus exhibits nuclear instability due to too many neutrons for the number of protons or vice versa, that nucleus may undergo beta decay. It the decay event occurs, that atom is considered a beta emitter. The emitted particle is the beta particle. That's the difference. (There are two different beta particles, so check the articles on beta decay to get the scoop.)
In alpha decay the parent element and the daughter element can be different isotopes of the same element but in beta decay the parent and daughter element are always the same?
No. In both the cases the element would definitely change. As alpha particle comes out then the new element would have two less in atomic number where as in beta particle decay the new element will have one higher in atomic number.
How are alpha and beta particles the same?
Alpha and beta particles are the same in that changes in unstable atomic nuclei can release alpha particles or can beta particles (depending on the isotope involved), and both are forms of particulate radiation.
Is alpha decay the same as alpha radiation?
No. Decay is the process, radiation is the product.
Do allpha beta and gamma rays come from same element?
No, alpha, beta, and gamma rays are not all produced by the same element. Alpha particles consist of two protons and two neutrons and are emitted during radioactive decay of heavy elements like uranium. Beta particles are electrons or positrons emitted during the decay of certain isotopes. Gamma rays are high-energy photons emitted during the transition of a nucleus to a lower energy state and are not particles.
What happens to the atomic number of an element if it emits 1 alpha particle and 3 beta particles?
It depends on whether the beta decay is beta- or beta+. The alpha emission reduces the atomic number by 2. Beta- increases the atomic number by 1 while beta+ decreases the atomic number by 1. You do the math.
Type of nuclear decay consisting of a helium nucleus?
Alpha decay. Alpha particles are the same as a helium-4 nucleus.
Is Thorium-234 Proactinium-234 -1 a alpha decay equation?
It's beta decay. Actually, it's beta minus decay. A neutron in the nucleus of thorium-234 undergoes beta minus decay and changes into a proton with the subsequent release of an electron, an antineutrino and some energy. The transformation of a neutron in the thorium nucleus into that proton creates another element. You'll recall that the identity of an element is determined solely by the number of protons in its nucleus. And our thorium atom has now become a protractinium-234 atom.
