Does alpha decay always decreases the number of protons by an even number?

Yes, an alpha radiation particle is 2 protons and 2 neutrons so for every alpha particle emitted the radioactive nuclide loses 2 protons.

How can you use the parent element to determine the daughter element in alpha decay?
In alpha decay, the atomic number decreases by 2, while the atomic mass number decreases by 4.
How does radioactivity create new elements?
One way that elements decay is by alpha-emission. That means that the nucleus of the atom spews out alpha particles. An alpha particle is made of two protons and two neutrons, like a helium nucleus. Of course, once an alpha particle is emitted, the number of protons in the nucleus decreases, and the element changes with the number of protons.
What changes take place in the nucleus when an alpha particle is emitted?
In short, alpha radiation occurs when an unstable nucleus emits 2 protons and 2 neutrons from it's nucleus. This means that the atomic number decreases by 2 and the nucleon number decreases by 4.
What happens to a radioactive nucleus when it emits gamma ray?
It's atomic number decreases by 2 (because it has lost two protons) but as an alpha particle is two protons and two neutrons the Atomic Mass decreases by 4.
The number of protons plus neutrons in an alpha particle?
2 protons and 2 neutrons. An alpha particle is the same as a helium nucleus.
What happens to the number of protons when U-238 emits an alpha particle?
The number of protons decreases by 2.
What happens to the atomic number when an alpha particle is given off?
Alpha emission in an atom reduces its atomic number by two. A link can be found below to the related question about what alpha decay is.
Which of the following processes alwyas decreases the number of protons by an even number 1 fusion 2 beta decay 3 alpha decay or 4 fission what is the correct answer?
not sure buh i thinkk its ionisation. if not lets kill my chem teacher....!!!!The radioactive process called "alpha emission" decreases the number of protons in a decaying atom by the even number 2.

What happens to atomic number and atomic mass of an atom that emits alpha particle?
An alpha particle is a positively charged nuclear particle consisting of two protons bound to two neutrons. The atomic number of an atom decreases by 2 and the mass number decreases by approximately 4 when an alpha particle is ejected.
What change is atomic number occurs when a nucleus emits an alpha particle?
An alpha particle is composed of two protons and two neutrons, so when an atom loses an alpha particle, its mass number decreases by four. However, since the atom loses two protons, it is now a different element. It is now the element with an atomic number minus the two protons.
What happens when an unstable nucleus decays via alpha radiation?
mass number decreases by 4atomic number decreases by 2the nuclei recoil quite strongly (compared to other modes of decay) due to the large mass of the alpha particle
A atom with a altered number of neutrons?
Two atoms with the same # of protons & electrons but different # of neutrons are called isotopes, which is what I assume you want. If the number of neutrons changes, and # protons increases, then there is a Beta - particle emitted. If # of protons decreases, then an alpha particle is emitted.
What particle consists of two protons and two neutrons it is the same as a helium nucleus release of a what particle by an atom decreases the atomic number by 2 and the mass number by 4?
an alpha particle
What happens to a radioactive nucleus when it emits gamma ray?
It's atomic number decreases by 2 (because it has lost two protons) but as an alpha particle is two protons and two neutrons the Atomic Mass decreases by 4.
