6 subatomic particles.
2 protons and 2 neutrons (that accounts for the mass of 4 amu) as well as 2 electrons.

An atom of helium with a mass of 4 Atomic Mass units (amu) would typically contain 4 subatomic particles. Two of these particles would be protons, two would be neutrons, and two would be electrons.

What would a carbon atom look and sound like if you were a subatomic particle?
It would look very small because subatomic particles are small.
Do alpha prarticle share the same atomic number?
An alpha particle is, essentially, a helium nucleus.This means that is has the same atomic number (no. of protons) as Helium does - it just doesn't have the electrons as well.So the atomic number of an alpha particle would be 2.It's also not neutral, and would have a 2+ charge.The mass number of an alpha particle would be 4 as it has 2 neutrons and 2 protons.All alpha particles are helium nuclei, so they all share the same properties.
Who study the black holes and subatomic particles?
Black holes and subatomic particles are a subject of interest in the fields of astronomy, astrophysics, and particle physics. Perhaps the most famous to bring to light the notion that black holes could emit particle/antiparticle pairs and thus lose mass through loss of energy would be Professor Stephen Hawking, who proposed that black holes interact with the universe thermodynamically in this way and could potentially evaporate entirely. This radiation is often known as Hawking radiation.
What are the subatomic particles of manganese?
Subatomic particles are the same for all substances that exist everwhere. So to ask "What are the subatomic particles of manganese?" is really not a good question. Manganese is an element. And like all elements, it is made up of atoms. Atoms are made up of.......subatomic particles! (Moledule)(Cation)(Ion)===>Element====>Atom====>Subatomic particle The are three basic subatomic particles: protons, electrons and neutrons. If you really want to get anal about it, you can also find out what neutrons are made up of. I would tell you, but I forgot!
What subatomic particle has a relative mass of 1?
The term nucleon is applied to any particle that makes up an atomic nucleus. That means it can be applied to either a proton or a neutron (but only when we are talking about them as the components of an atomic nucleus). The nucleon with the positive charge is the proton. You'll recall that the neutron is a neutral particle; it has no charge.
How many of each subatomic particle would be present in an atom of helium with a mass of 4 amu?
2 protons, 2 electrons and 2 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.
What is a subatomic particle with two neutrons that is emitted during some types of radioactive decay called?
This would be the alpha particle. An alpha particle has two neutrons and two protons, and it's actually a helium-4 nucleus. That's why we write this particle like this: 42He or He+2 Use the links below for more information.
What would a carbon atom look and sound like if you were a subatomic particle?
It would look very small because subatomic particles are small.
Subatomic particle that defines the element?
Protons, electrons and neutrons
Where would you find the subatomic particle?
sub-atomic would indicate that it would be found inside an atom.
What subatomic particle carries a negative electric charge?
The electron is the most important subatomic particle with a negative charge. There are others, however.Electron. Muon. Quarks: down, strange, and bottom.electron
Which subatomic particle has the weakest charge?
I would say a neutrino, because its charge is zero. ------------------------------------------------------------------------ Neutrino is not considered as a subatomic particle. Proton (positively charged) and electron (negatively charged) have very small electrical charge.
How would you measure a subatomic particle?
These measurements are the result of experiments or are derived from other physical data.
Which noble gas would have the smallest ionic radius?
Helium would have - it is an alpha particle.
The Subatomic particle of an atom with negative change?
that would be an electron, protrons are positive and nutrons you guessed it neutral
Which particle did j.j. Thomson discover?
The first discovery of a subatomic particle would come in 1897, when J.J. Thompson first discovered evidence for the existence of the electron.
