Two parts of an atom nuclus?
neutrons and protons electrons are on the outer shell
What two things make up the nucleus of an atom '?
Protons and neutrons make up the nucleus of an atom. Protons have a positive charge, and neutrons have no charge. Electrons orbit around the nucleus.
How many protons and nuetrons are in helium?
The normal helium atom has two protons and two neutrons in the nucleus, and two electrons in the "shell".
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.
What contributes to the most of the mass of an atom?
The majority of the volume in an atom is filled by the neutrons and the protons. Although the electrons do have a volume, they occupy significantly less space than the other two subatomic particles
What are the two particles called in the centre of an atom?
Nucleus (and it consists of protons and neutrons).
What are two particles in an atom?
There're two particles in the atom nucleus (protons and neutrons)
Two parts of an atom nuclus?
neutrons and protons electrons are on the outer shell
What two particles are in the nucleus?
(The constituent particles of an atom are the electron, the proton and the neutron; all three are fermions. However, the hydrogen-1 atom has no neutrons and the hydron ion has no electrons.) WIkipedia

Protons and neutrons are located in the nucleus of the atom?
The atom is composed of two parts, the nucleus, which contains the Protons and neutrons, and is positively charged; and the negative electrons surrounding it.

How many protons neutrons and electrons will positive two ion of calcium have?
A positive two ion of calcium will have 20 protons, 18 neutrons, and 18 electrons. The number of protons and neutrons in a calcium ion remains the same as in a neutral calcium atom (calcium has 20 protons and about 20 neutrons in its nucleus), but it loses two electrons to become positively charged.
What two particles are found in the nucleus?
The neutral particles found in the nucleus on an atom are called neutrons. Positive particles found in the nucleus are protons.
