Any atom with two protons has an atomic number of two and is an isotope of helium. With two neutrons, there are a total of nucleons is four, so the isotope or mass number is four (sum of protons plus neutrons). Therefore the atom is helium-4 or 4He, which is stable (not radioactive) and the most common isotope of helium in nature, account for nearly 100% of all helium.
What else can I help you with?
Which subatomic particle is present in the nucleus of an atom?
The atomic particles that make up an alpha are two protons and two neutrons. The subatomic particles are contained within the neutrons & protons and there are too many to list here, plus I don't know all of them.
The radioactive particle that is positively charged and has two protons and two neutrons is the?
An alpha particle consists of two protons and two neutrons.
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 is negatively charged atomic particle?
In an atom, electrons have a negative charge. The other two atomic particles that are in atoms are neutrons and protons. Neutrons have a neutral charge and protons have a positive charge.
How many nucleons does an alpha particle contain?
An ALPHA particle may be thought of a a helium nucleus. It contains two protons and two neutrons. An alpha particle is a high speed helium nucleus (He^(2+)).
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 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 subatomic particle is present in the nucleus of an atom?
The atomic particles that make up an alpha are two protons and two neutrons. The subatomic particles are contained within the neutrons & protons and there are too many to list here, plus I don't know all of them.
The radioactive particle that is positively charged and has two protons and two neutrons is the?
An alpha particle consists of two protons and two neutrons.
What is the composition of an alpha particle, which consists of two protons and two neutrons?
An alpha particle is composed of two protons and two neutrons.
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?
The particle that consists of two protons and two neutrons, equivalent to a helium nucleus, is an alpha particle. When an atom releases an alpha particle, its atomic number decreases by 2 and its mass number 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 particle ads mass but no charge to the atomic nucleus?
The particle that adds mass but no charge to the atomic nucleus is the neutron. Neutrons are one of the two primary components of atomic nuclei, along with protons. While protons carry a positive charge, neutrons are neutral, contributing to the overall mass of the nucleus without affecting its charge. This balance of protons and neutrons is crucial for the stability of atomic nuclei.
What is a subatomic particle that is part of a structure of the atomic nucleus?
Atomic nuclei have two kinds of subatomic particles, which are protons and neutrons.
What element has atomic structure similar to an alpha particle?
The element with atomic structure similar to an alpha particle is helium. An alpha particle consists of two protons and two neutrons, the same as the nucleus of a helium atom.
What is negatively charged atomic particle?
In an atom, electrons have a negative charge. The other two atomic particles that are in atoms are neutrons and protons. Neutrons have a neutral charge and protons have a positive charge.
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.
