Is silver positively charged
WitrynaColloidal particles always carry an electric charge. This charge may be positive or neagtive. From the data given, Negatively charged sols are: P t, A u, A g, A s 2 S 3, … WitrynaA neutral conducting sphere is charged by induction using a positively-charged balloon. Explain how the object acquires a charge. The sphere becomes polarized. Electrons flow from the hand to the sphere. The sphere ends with a negative charge. Describe the steps that occur when a bolt of lightning forms.
