The alpha particle does not have any electrons. This particle is ejected from the nucleus of an atom in what is called alpha decay, and it appears as a pair of protons and a pair of neutrons fused together. The alpha particle is a helium-4 nucleus, and soon after it appears, it will collect a pair of electrons from its environment. But as it appears in the radioactive decay process, it doesn't have any electrons.

What neutrons are in an alpha particle?
A nucleon is the amount of protons and neutrons. An alpha particle has an atomic number of 2 and a atomic mass of 4 then it has 2 protons and 2 neutrons.There are 4 nucleons in an alpha particle.
What element has the same number of protons and neutrons in its nucleus as an alpha particle?
An alpha particle has 2 protons and 2 neutrons. That is the same as a helium nucleus.
Are there more protons than electrons in an alpha particle?
Yes.An alpha particle is the nucleus of a helium atom, with no electrons. There are 2 protons and 2 neutrons.
When an unstable nucleus produces an alpha particle by how many units does the atomic number of the nucleus change?
An alpha particle is a helium nucleus, which consists of 2 protons and 2 neutrons. When an unstable nucleus emits an alpha particle, it loses 2 protons, which means its atomic number will be reduced by 2.
Why does an alpha particle have a charge of 2 positive?
The alpha particle (which is a helium nucleus), is composed of two protons and two neutrons. The two protons give it a charge of +2.
What type of radioactive particle has 2 protons?
An alpha particle has two protons.
What neutrons are in an alpha particle?
A nucleon is the amount of protons and neutrons. An alpha particle has an atomic number of 2 and a atomic mass of 4 then it has 2 protons and 2 neutrons.There are 4 nucleons in an alpha particle.
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.
Which particle is composed of 2 neutrons and 2 protons?
An alpha particle.
What element has the same number of protons and neutrons in its nucleus as an alpha particle?
An alpha particle has 2 protons and 2 neutrons. That is the same as a helium nucleus.
Are there more protons than electrons in an alpha particle?
Yes.An alpha particle is the nucleus of a helium atom, with no electrons. There are 2 protons and 2 neutrons.
Is it true that an alpha particle consists of two protons and neutrons?
Yes it is. an alpha particle can be represented as 2He4
Which atoms are in an alpha particle?
An alpha particle is two protons and two neutrons, this is the same as a helium nucleus.
When a Uranium 238 emits an alpha particle the nucleus left behind has how many protons?
90 protons left
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.
Which is an alpha particle?
A helium nucleus (2 protons & 2 neutrons).
How many nucleons does an alpha particle contain?
Four. Two protons and two neutrons.
