Atomic structure :

There are principally 2 type of charged particles, a light and negatively charged electron, a much heavier positively charged proton, and an electrically uncharged (neutral) particle of about same mass as the proton called a neutron.

Thus all charged particles get combine and form an Atom.

Atom - Let we consider about a chair it made by wood, wood is made by particle and particle is made by atoms. Atoms is made by electron protons and neutron. The nucleus of an atom are made by protons and neutrons. Electron are moving around nucleus like planet moving around sun.

The nucleus is the very dense region consisting of protons and neutrons at the center of an atom. It was discovered in 1911 as a result of Ernest Rutherford's interpretation of the 1909 Geiger-Marsden gold foil experiment performed by Hans Geiger and Ernest Marsden under Rutherford's direction. The proton"neutron model of nucleus was proposed by Dmitry Ivanenko in 1932. Almost all of the mass of an atom is located in the nucleus, with a very small contribution from the electron cloud.

The diameter of the nucleus is in the range of 1.75 fm (1.75x10^-15 m) for hydrogen (the diameter of a single proton)[not in citation given] to about 15 fm for the heaviest atoms, such as uranium. These dimensions are much smaller than the diameter of the atom itself (nucleus + electron cloud), by a factor of about 23,000 (uranium) to about 145,000 (hydrogen).

The branch of physics concerned with studying and understanding the atomic nucleus, including its composition and the forces which bind it together, is called nuclear physics.

Yes nucleus is made up of proton and neutron but electron revolve around the nucleus.

Nucleus is the combination of protons & neutrons. So, it will be +ve charge.

Nucleus is made up of protons and neutron.

Proton & neutron are together in the nucleus.

Ashu said; The nucleus consists positively charged protons and neutral neutrons in it. And negatively charged electrons revolving around the nucleus.

The nucleus is +vely charged species around which electrons revolve in circular orbits.

Nucleus consists of protons and neutrons, they are known as nucleons.
