An atom is primarily composed of three types of subatomic particles: protons, neutrons, and electrons. Protons carry a positive charge, while electrons have a negative charge; neutrons are neutral and carry no charge. Protons and neutrons are located in the nucleus at the center of the atom, while electrons orbit around the nucleus in various energy levels. Together, these particles determine the atom's chemical properties and overall charge balance.

What are the particles that compose an atom and identify the electrical charge of each particle?
An atom is composed of three main particles: protons, neutrons, and electrons. Protons have a positive electrical charge, neutrons have no electrical charge (neutral), and electrons have a negative electrical charge.
What is a sub-atomic particle?
A subatomic particle is something smaller than an atom. These are further broken up into elementary and composite subatomic particles. Electrons are elementary, whereas protons and neutrons are composite and can still be further broken down.
How do the electric charges of alpha particles beta particles and gamma rays differ from each other?
From Physics Forums The alpha particle has a 2+ charge, beta has 1- charge, and the gamma is neutral (no charge). The beta particle could also have a 1+ charge if it undergoes positron emission [a proton turns into a neutron and a positron (the "anti-electron")]
Why don't all of the particles in an atom contribute to the charge?
In an atom, the charge is primarily determined by the protons and electrons. Protons have a positive charge, while electrons have a negative charge, and their charges balance each other out in a neutral atom. Neutrons, which are also present in the nucleus, carry no charge and therefore do not contribute to the overall charge of the atom. Thus, only the charged particles—protons and electrons—are relevant for determining the atom's net charge.
Why does an atom have an overall neutral charge in regard to subatomic particles?
A proton has a charge of (+1) and an electron has a charge of (-1) and neutrons do not have a charge. In an atom there are an equal numbers of protons and electrons so the charges cancel. If there are a different number of protons and electrons, the particle is no longer an atom, but instead an ion.
What are the particles that compose an atom and identify the electrical charge of each particle?
An atom is composed of three main particles: protons, neutrons, and electrons. Protons have a positive electrical charge, neutrons have no electrical charge (neutral), and electrons have a negative electrical charge.
What is the charge on each subatomic particle?
For the atom: Neutron: Charge: neutral Electron: Charge: negative Proton: Charge: positive
What are the three atomic particles and the charge of each particle?
Neutron - no charge, Proton +1, Electron -1
What is a no charge particle called?
There are three basic types of atomic particles. Electrons, which have a negative charge, protons with a positive charge and neutrons, which have no charge.
What is a sub-atomic particle?
A subatomic particle is something smaller than an atom. These are further broken up into elementary and composite subatomic particles. Electrons are elementary, whereas protons and neutrons are composite and can still be further broken down.
What describes protons?
Protons are positively charged particles found inside the nucleus of an atom. The number of protons in each atom is its atomic number. The name proton was given to the hydrogen nucleus by Ernest Rutherford in 1920.
What part of a atom causes particles to bounce back?
The positively charged nucleus of the atom, which contains protons and neutrons, is what causes particles to bounce back due to electrostatic repulsion. When an incoming particle has the same charge as the nucleus, such as another positively charged particle, they will repel each other, causing the incoming particle to bounce back.
How do the electric charges of alpha particles beta particles and gamma rays differ from each other?
From Physics Forums The alpha particle has a 2+ charge, beta has 1- charge, and the gamma is neutral (no charge). The beta particle could also have a 1+ charge if it undergoes positron emission [a proton turns into a neutron and a positron (the "anti-electron")]
What are the Example of a proton and neutron?
A proton is a positively charged particle in the center of an atom. A neutron is another particle in the center of an atom that has no charge, but still has mass. Each particle, sometimes called a subatomic particle, has a mass of one AMU. The sum of these is the mass of one atom of an element. Electrons, the particles orbiting the nucleus, where protons and neutrons reside, are not taken into account in massing because they are so small.
What is the electric charge of each particle in an atom?
Proton: positive Electron: negative Neutron: neutral
What is the electrical charge of each particle in the atom?
Proton: positive Electron: negative Neutron: neutral
