Model B: In this model the atom is a solid sphere that cannot be divided up into smaller particles or pieces. The atom is neutral and has no charge. Atoms of the same element are

mad of the same types of atoms.

Model D: In this model the atom is a sphere containing negatively charges particles

embedded in it. These small negative particles were originally called “corpuscles”

and later called electrons. However it was recognized that the atom is neutral (no

charge) so there must be an equal positive charge in the atom to offset the negative

charge of the electrons. Since no other particles were known at this time the rest of

the atom consisted of a positive charge.

It is possible to remove a negatively charged particle from an atom using electrical forces

(Thompson, 1897). Compare models B and D. Which model supports this evidence?

explanation:

metals have excess of electrons whereas non-metals have deficiency of electrons. thus, in order to gain stability metals easily donate their electrons to the non-metals.

for example, electronic configuration of sodium is and electronic configuration of phosphorous is .

when a phosphorous atom and sodium atom combine together then sodium will donate is extra one electron to the phosphorous atom. as a result there will be formation of ionic bond between sodium and phosphorous.

the reaction will be as follows.

there, are three sodium sodium atoms and each of them will donate its one extra electron to phosphorous atom. thus, the sub-shell of phosphorous gets completely filled.  

thus, we can conclude that electrons are transferred from atoms of sodium to atoms of phosphorous. this transfer makes the sodium atoms donate one electron and the phosphorous atoms to gain one electron. as a result, the sodium and phosphorus atoms strongly attract each other.
