Identify the scientist the theory John Dalton
J.J Thompson Ernest Rutherford Niels
Bohr electron cloud
John Dalton
1) chemical elements are made of atoms. 2) the
atoms of an element are identical in their masses
3) atoms of different elements have different
masses 4) atoms only combine in small, whole
number ratios such as 11, 12, 23 and so on.
5) atoms can be neither created nor destroyed

Identify the scientist the theory John Dalton
J.J Thompson Ernest Rutherford Niels
Bohr electron cloud
Ernest Rutherford
described the atom as a tiny, dense, positively
charged core called a nucleus, in which nearly
all the mass is concentrated, around which the
light, negative constituents, called electrons,
circulate at some distance, much like planets
revolving around the Sun

Nucleus- center of the atom . Contains
positively charged protons and neutral neutrons

Negatively charged electrons orbit the nucleus in
orbital (shells). Electrons are so small it is
not considered when calculating atomic mas
