Atom is cutable partical ,but atom subatomic particles election,proton and neutron परमाणु वियोज्य कण नहीं है, बल्कि परमाणु उपपरमाण्विक कण इलेक्ट्रॉन, प्रोटॉन और न्यूट्रॉन हैं An atom is the smallest constituent unit of ordinary matter that constitutes a chemical element . Every solid , liquid , gas , and plasma is composed of neutral or ionized atoms. Atoms are extremely small; typical sizes are around 100 picometers ( 1 × 10 −10 m , a ten-millionth of a millimeter, or 1/254,000,000 of an inch). They are so small that accurately predicting their behavior using classical physics – as if they were billiard balls , for example – is not possible. This is due to quantum effects . Current atomic models now use quant...

Atomic number Atomic number Definition :- Atomic number is the number of protons in nucleus. eg. Helium About explanation of the superscripts and subscripts seen in atomic number notation. Atomic number is the number of protons, and therefore also the total positive charge, in the atomic nucleus. The Rutherford–Bohr model of the hydrogen atom ( Z = 1 ) or a hydrogen-like ion ( Z > 1 ). In this model it is an essential feature that the photon energy (or frequency) of the electromagnetic radiation emitted (shown) when an electron jumps from one orbital to another be proportional to the mathematical square of atomic charge ( Z 2 ). Experimental...
