Answer:
Option - 2, 3, 7, 8
Step-by-step explanation:
The electric charges can be either positive or negative. The negative charges are due to the electrons which are able enough to move across the atom and from one atom to the other. The positive charge is due to the proton and unlike electron its position is fixed.
Negative and positively charged atom or molecule gets attracted towards each other while atoms or molecule with similar charges repel each other. Electric charges create an electric field around themselves.
Hence, option 2, 3, 7, 8 are correct
