An atom consists of a heavy small nucleus in the center and electrons revolving around it. Nearly all mass is concentrated in the nucleus. The electrons are forming a cloud around the nucleus because they are moving with an enormous speed. Take an example of an atom of Carbon. It has 6 protons and 6 neutrons in the nucleus and 6 electrons revolving around it. Its mass is 12 atomic units and the it has a valency of 4.
The nucleus of carbon has a mass of 1.92x10^-26 Kg whereas the six electrons have a total mass of 9.11x10^-31 Kg. We can, in some cases ignore the mass of electros all together. On the other hand the size(radius) of the nucleus of carbon-12 is 2.7x 10^-15m and the size(radius) of an atom of C-12 is 1.7x10^-10m. The density i.e mass per unit volume of C-12 is 2.26x10^3 Kg/m^3 and the density of nucleus of C-12 is 1.7x10^17Kg/m^3.
Try calculating it by yourself. It is interesting.
Visualize if all the electrons were detached from the nucleus and we have a nuclear mass, how much heavy it will be?
Atomic nucleus is made up of neutrons ie chargeless particles and protons with positive charge on it. These are two main constituents. But these are held together so tight because of exchange of mesons in between them. So mesons too are there within the nucleus. Each neutron would split into a proton and an electron if such an opportunity occurs. Hence hidden electrons are there within each neutron. Generally energy has so many forms. Especially in case of nucleus it is apparent that energy is mostly seen as protons, neutrons and mesons.
Protons (they have a positive charge) and Neutrons (they have no charge);
This is true, except for the nucleus of Hydrogen which is only ONE proton, no neutrons in it; however Deuterium [Heavy Hydrogen] is a proton combined in the Atom's nucleus with a neutron and Tritium [Extra Heavy Hydrogen] is a proton combined in the Atom's nucleus with two neutrons.
Protons and neutrons and mesons.
The nucleus of an atom is made up of protons and neutrons. Protons have a positive charge, while neutrons have no charge. These particles are held together by the strong nuclear force.
An atom is made up of Protons Neutrons and Electrons.
In the nucleus (protons and neutrons)
in the shells (electrons)
A nucleus always contains at least one proton and almost always also has one or more neutrons.

The central part of an atom is called the?
The central part of an atom is called the nucleus. Within the nucleus are protons and neutrons, which make up the majority of an atom's mass.
Is the center of an atom a neutron?
No, the center of an atom is the nucleus, which is made up of protons and neutrons. Neutrons are subatomic particles found within the nucleus along with protons.
Which subatonic particles are found in the nucleus of an atom?
Protons and neutrons are the subatomic particles found in the nucleus of an atom. Electrons surround the nucleus in electron clouds.
What is the core of an atom called?
Atoms are made of a nucleus that is surrounded by electron clouds. The nucleus is formed from all the atom's protons and neutrons. Proton and neutrons are made up of even smaller particles called quarks.
Where are the nucleus and the electron located in one atom?
The nucleus is located at the center of the atom, containing protons and neutrons. Electrons orbit around the nucleus in specific energy levels or shells.
What is the nucleus in the center of a atom made of?
The center of an atom is made up of protons and neutrons it's called the nucleus.
What does the nucleus is made at of?
The nucleus of an atom is made up of protons and neutrons.
The Nucleaus of an atom is made from what?
The nucleus of an atom is made up of protons and neutrons. Protons have a positive charge, while neutrons have no charge. Electrons move around the nucleus in electron shells.
The central part of an atom is called the?
The central part of an atom is called the nucleus. Within the nucleus are protons and neutrons, which make up the majority of an atom's mass.
Is nucleus smaller than atom?
An atom comprises an atomic nucleus with orbiting electrons. So the nucleus is smaller than an atom. To phrase it the opposite way, an atom is alwys larger than the nucleus (of the same atom of course!!)
Where are the nucleus and the electrons located in the atom?
The nucleus is the center of an atom and is made up of protons and neutrons. Electrons freely orbit around the nucleus.
Where are the nucleus and electrons located in the atom?
The nucleus is the center of an atom and is made up of protons and neutrons. Electrons freely orbit around the nucleus.
Where is the nucleus found in the atom?
The nucleus is the dense center of an atom made of neutrons and protons surrounded by clouds of electrons.
Is mass located in an atom's nucleus or in its protons?
The mass of an atom is concentrated in the nucleus, which is made up of protons and neutrons.
What is a atom's nucleus made of?
Protons and neutrons
What is inside the nucleus of an atom?
The nucleus of an atom contains neutrons and protons. Almost all of the mass in an atom is made up from the protons and neutrons in the nucleus. Because the nucleus is only made up of protons and neutrons, it is positively charged. Physicists believe that there is a cluster of Protons and Neutrons within an Atom's nucleus. Friend Premier is quite right. So instead saying inside the nucleus it would be apt to say that nucleus is made up of...
Is the center of an atom a neutron?
No, the center of an atom is the nucleus, which is made up of protons and neutrons. Neutrons are subatomic particles found within the nucleus along with protons.
