Point Carly draws a map of surface currents in the Atlantic Ocean. On her map,
she includes the major wind belts for the same area. Her map is similar to
the one shown. If Carly wants to add wind belts for the part of the Atlantic
just south of the equator, how should she draw the arrows?

The arrows should curve upward to the left
The arrows should curve upward to the right
The arrows should curve downward to the left.
The arrows should curve downward to the right

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.
