(1) All substances are made up of basic units called atomicatomselectronselementsnegativelyneutronsnucleusnumberorbitsparticlespositivelyprotonssub-atomic, which are themselves made from three different atomicatomselectronselementsnegativelyneutronsnucleusnumberorbitsparticlespositivelyprotonssub-atomic atomicatomselectronselementsnegativelyneutronsnucleusnumberorbitsparticlespositivelyprotonssub-atomic.

(2) In the centre of an atom is the atomicatomselectronselementsnegativelyneutronsnucleusnumberorbitsparticlespositivelyprotonssub-atomic consisting of atomicatomselectronselementsnegativelyneutronsnucleusnumberorbitsparticlespositivelyprotonssub-atomic charged atomicatomselectronselementsnegativelyneutronsnucleusnumberorbitsparticlespositivelyprotonssub-atomic and neutral atomicatomselectronselementsnegativelyneutronsnucleusnumberorbitsparticlespositivelyprotonssub-atomic.

(3) Moving around the atomicatomselectronselementsnegativelyneutronsnucleusnumberorbitsparticlespositivelyprotonssub-atomic are atomicatomselectronselementsnegativelyneutronsnucleusnumberorbitsparticlespositivelyprotonssub-atomic charged atomicatomselectronselementsnegativelyneutronsnucleusnumberorbitsparticlespositivelyprotonssub-atomic in specific energy levels you can simply envisage as 'atomicatomselectronselementsnegativelyneutronsnucleusnumberorbitsparticlespositivelyprotonssub-atomic'.

(4) Particular types of atoms are called atomicatomselectronselementsnegativelyneutronsnucleusnumberorbitsparticlespositivelyprotonssub-atomic and all the atoms of one type have the same number of atomicatomselectronselementsnegativelyneutronsnucleusnumberorbitsparticlespositivelyprotonssub-atomic in the central atomicatomselectronselementsnegativelyneutronsnucleusnumberorbitsparticlespositivelyprotonssub-atomic, which is called the atomicatomselectronselementsnegativelyneutronsnucleusnumberorbitsparticlespositivelyprotonssub-atomic atomicatomselectronselementsnegativelyneutronsnucleusnumberorbitsparticlespositivelyprotonssub-atomic.
