Kamal is experimenting with an electron beam. He brings a metal bar close to the beam. The path of the beam does not change. What can be said about this metal bar?
Select all that apply.
-The metal bar may be magnetic
-The metal bar is not electrically charged.
-The metal bar may be electrically charged.
-The metal is not magnetic

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.

hope this !

and sorry if i'm late. have a good rest of your day! : d
