The unit Cells repeats itself in three dimensional space to form the structure. Total number of protons in the nucleus is called theatomic numberof the atom and is given thesymbol Z. Research in high-energy particle physics in the 20th century revealed that neither the neutron nor the protonis notthe smallest building block of matter. Scientist Henry Gwynn Jefferies Mosle examined the X-ray spectrum of various elements from 1913-to 1914. Isotopesare nuclides that have the same atomic number and are therefore the same element, but differ in the number of neutrons. The number of electrons and protons in an atom is the same but the number of neutrons is different. The degree to which orbitals with different values of l and the same value of n overlap or penetrate filled inner shells results in slightly different energies for different subshells in the same principal shell in most atoms. For example, a 1s electron (Figure \(\PageIndex{3}\); purple curve) has greater electron density near the nucleus than a 2p electron (Figure \(\PageIndex{3}\); red curve) and has a greater penetration. Therefore, the number of negatively charged electrons orbiting in its orbit is equal to the number of positively charged protons in the nucleus.
