how to make a diagram of lithium atom based on thomsons atomic model?

Answer 1

Thomson believed that atoms contained only positive and negative particles, and that those particles were evenly distributed throughout the atom. To make a diagram you would draw a circle and evenly space 3 positive charges and 3 negative charges. It is called the "plum pudding" model of the atom because Thomson described it as having the + and - charges "spread out like the currants and raisins in plum pudding." Think about holding a hand full of red and green m&ms. They are evenly mixed.

Answer 2

Atomic Model Of Lithium

Answer 3

This question is abit more subtle than most on the subject and actually kind of tricky.

Thomson believed that the positive material was a light (low mass), jelly-like substance. The electrons (or as Thomson puts it "corpuscles" contained most of the mass of the atom. Different elements would therefore have a different numbers of electrons (since the concept of atomic weight was both known and measureable at that time) per *solid* atom.

So your diagram should show a circle with 3 e- particles in it and a label to the positive jelly.

See link below for more discussion as well a link to Thomson's 1904 paper where he describes his model.
