Step 5: Measure the Volume of Each Regularly Shaped Ball What is the volume of the golf ball?
cm3
The volume of the water in the graduated cylinder rose
as some of the water was displaced by the golf ball. Find
the volume of the ball using the formula
V = V;-V
where V, is the volume of the ball, V, is the final volume
of the water, and V, is the initial volume of the water.
Record the volume of the ball in Table A of your Student
Guide.

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.
