J.J. Thomson hypothesized and discovered that the atom was not the smallest unit of matter but that instead there were much smaller units. He discovered "sub-atomic particles" which make up atoms. The sub-atomic particle that Thomson discovered was the electron. He discovered this through a process of experiments testing cathode rays.

How to balance lead and silver acetate yields lead (||) acetate and silver
arsen [322]
The given elements put into an equation using their symbols  are as follows:
Pb + AgC_{2}H_{3}O_{2} = Pb(II){(C_{2}H_{3}O_{2})_2} + Ag

Since there are 2 Pb on the right side of the equation, you would change the coefficient of Pb on the left side to 2:
2Pb + AgC_{2}H_{3}O_{2} = Pb(II){(C_{2}H_{3}O_{2})_2} + Ag

Since there are 2 Acetate on the right side of the equation, you would change the coefficient of Silver Acetate on the left side to 2:
2Pb + 2AgC_{2}H_{3}O_{2} = Pb(II){(C_{2}H_{3}O_{2})_2} + Ag

Now there are 2 Silver on the left side, so you change the coefficient of Silver on the right side to 2:
2Pb + 2AgC_{2}H_{3}O_{2} = Pb(II){(C_{2}H_{3}O_{2})_2} + 2Ag

That is your final equation

The coefficients are 2 + 2 = 1 + 2
