Electric Charges
Electric charges: We already know that atoms are made of protons neutrons and electrons. The positively charged particles in an atom are called protons. The negatively charged particles are called electrons. The atom as a whole consist of an equal number of positive and negative charges, and in such a case of the atom is said to be electrically neutral. If, however the charges are not balanced, the object will have an electric charge (positive charge if protons are more in number than electrons and negative charge if electrons are more in number than protons. If two objects having the same type of charge are brought close together, they repel each other (i.e. push each other away) however if the two objects having the opposite type of charge. (positive- negative or negative-positive), they attract each other. Therefore, we can say, like charges repel each other and unlike charges attract each other
