When an atom gains electrons, it becomes (1) (yvenagltie) charged.<br />
When an atom loses electrons, it becomes (2) (lsoipyviet) charged. The<br />
law of conservation of charge states that charge can not be (3) (dracete)<br />
or (4) (reddeosty), only transferred from object to object. Objects with<br />
equal amounts of positive and negative charge are said to be electrically<br />
(5) (traulen). Some objects hold (6)<br />
(neetlorcs) more tightly than others, so when two different objects, such as carpet and<br />
shoes, are rubbed together, the electrons are (7) (serfarntred)<br />
from one to the other. An accumulation of excess charge on an object is called<br />
(8) (tastci leecrtcyii).<br />
