Q

basic unit of an element

A

atom

36
Q

in 15th century he proposed that matter is made up of small particles called atomos

A

Democritus

37
Q

in 1704 he proposed a mechanical universe with small solid masses in motion

A

Isaac Newton

38
Q

in 1808 proposed the Atomic Theory with spherical solid atoms based upon measurable properties of mass

A

John Dalton

39
Q
  1. Each element is composed of a small particle which is called atom
  2. all atoms of an element is identical, having the same size, mass and chemical properties. the atom of an element is different from the atom of all elements
  3. compound is made up of one atom of more than 1 element
  4. chemical reaction involves only separation, recombination, and rearrangement of atom. it does not result in their creation or destruction
A

A

Neils Bohr

46
Q

in 1923 he discovered that electron have dual nature - similar to particles and waves

A

Louis De Broglie

47
Q

in 1927 he proposed the principle of indeterminacy

A

59
Q

as the n+1 value increases, the energy of electrons also increases

A

N1+ rule

60
Q

the number of electrons is equal to the atomic number. the electron added will enter the orbitals in the order of increasing energy. orbitals cannot take more than 2 electrons.
