Describe the location of the negative charges of the atom in j.j thompsons plum pudding model
iren2701 [21]

The location of the negative charges is evenly distributed throughout the entire atom.

J. J. Tomson concluded that atoms are divisible and that the corpuscles are their building blocks.

Atoms are made up of smaller particles.

J. J. Thomson discovered the electron ( the negative charges of the atom) in 1897.

His "plum pudding" model (1904) suggested: the electrons are embedded in the positive charge and evenly distributed throughout the entire atom.

With this model, he abandoned his earlier hypothesis that the atom was composed of immaterial vortices.

Later, Rutherford demonstrate that J.J Thompson's Plum Pudding model was not accurate.

What mass of cu(s) is electroplated by running 26.5 a of current through a cu2+(aq) solution for 4.00 h?
kramer
T = 14400 s 
26.5 x 14400=381600 C 
381600/96500=3.95 Faradays 
Cu2+ + 2e- = Cu 
3.95 faradays ( 1 mol/ 2 Faradays) = 1.97
mass = 1.97 x 63.55 g/mol=125 g 

moles Au = 33.1 / 196.967 g/mol=0.168 
Au+ + 1e- = Au 
0.168 ( 1 Faraday/ 1mol)= 0.168 Faraday 
0.168 x 96500=16217 Coulombs 
16217 / 5.00=3243 s => 54 min
