Atom A Smallest Particle of Matter

Atom A Smallest Particle of Matter

A matter ex. copper,silicon,carbon,iron are the combination of multiple small particles of Atom.Every matters may be solid liquid or gas, all of these having smallest particles called as Atom.

 the above figure shows helium atom. At the centre of any atom has nucleus. Nucleus consist number of proton and neutron in same quantity. 99.94% mass of atom consist in nucleus.
The black cloud shows the electron.due to very high electron circulate around nucleus ,electron seen as cloud and blur at outer to inner.

Part of Atom: Neutron,Proton and Electron

• Neutron: It present at centre of atom with proton with same number of quantity. it have no charge means it is neutral.(No-Charge)
• Proton: It present at the centre of atom with same no. of  Neutron. It Have positive charged.  (+ve Charged)
• electron: It present outside of nucleus and circulate around. Speed of circulation is very high hence it seen as cloud.It have Negative Charge(-ve Charged)
