What is the relative electrical charge of a sodium (Na) ion with 13 electrons? A. -13
B.+2
C.+13
D.-2

relative humidity is a measure of the amount of moisture in the air relative to the total amount of moisture the air can hold.

so d

metals are good conductor of electricity. it has free electrons on their surface. according to electron pool theory, each atom present in a metal crystal losses all of its valence electron and as a result a pool of free is form. these pool of electrons are free to move and   conduct electricity easily   while making metal as good conductor.

the correct answer is a. the ability of electrons to flow throughout the metal.
