An alpha particle is a helium-4 nucleus. When it captures a pair of electrons, it becomes a helium-4 atom. Alpha particles released in nuclear decay events quickly pick up a pair of electrons from the environment and become those helium atoms, and the atom is said to be electrically neutral.

What is lost from the nucleus of atom when it emits an alpha particle?
2 neutrons and 2 protons (this is what an alpha particle is made up of).
What change in mass occurs when a radioactive atom emits an alpha particle?
4 from the alpha. Betas have negligible mass and gammas have no mass.
Can an atom gain or lose protons why or why not?
Yes, but only in nuclear reactions. If an atom emits an alpha particle, it will lose two protons to the emitted particle.
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.
Over time what will happend to the nucleus of a radioactive atom If a radioactive atom emits an alpha particles them what is it emitting?
Alpha particle is the same as a helium-4 nucleus, i.e., two protons and two neutrons bound together. If an atom emits an alpha particle, it will have two protons less, and two neutrons less. Over time, there may be additional decay, which may further change the number of protons and neutrons.

Yes, but only in nuclear reactions. If an atom emits an alpha particle, it will lose two protons to the emitted particle.
What is the change in the atomic number when the atom emits an alpha particle?
The atomic number will decrease by 2, the number of protons in the emitted alpha particle. An alpha particle is a helium-4 nuclei with two protons and two neutrons.
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.
The nucleus of a helium atom is called?
The nucleus of a helium atom is called an alpha particle. The electromagnetic waves emitted by a nucleus are called gamma rays.
Over time what will happend to the nucleus of a radioactive atom If a radioactive atom emits an alpha particles them what is it emitting?
Alpha particle is the same as a helium-4 nucleus, i.e., two protons and two neutrons bound together. If an atom emits an alpha particle, it will have two protons less, and two neutrons less. Over time, there may be additional decay, which may further change the number of protons and neutrons.
Does an alpha particle undergo electromagnetic radiation?
Yes alpha particle goes under goes electromagnetic radiations. when an atom is exposed to the magnetic field the alpha particle deviates right through right direction which indicates does have capacity to excite and emits radiations to come to ground level.
Is an alpha particle is identical to the nucleus of a?
An alpha particle is identical to the nucleus of Helium atom
What is the nuclear equation for the alpha decay of radon and minus 198.?
If an atom emits an alpha particle, that means that it emits a helium-4 nucleus - in other words, 2 protons + 2 neutrons.You need to subtract 2 from the atomic number, and 4 from the atomic mass.
When an alpha particle is outside the nucleus what happens to it?
It soon captures electrons, becoming an ordinary helium atom.
What is the charge of the atom when an alpha particle emit from that atom?
2-
