The charge is 2- (2 minus). This is because sodium ion has a charge of 1+ and 2 of them are there in the compound. Thus the charge is 2-
Answer:
The particles of matter are in constant motion.
Explanation:
Let us consider each statement:
1) Matter consists of only large molecules: No it is not necessary that matter consists of only large molecules, it depends upon the nature of matter.
2) Matter is made up of only charged particles: no the matter may have any kind of particles charged or uncharged.
3) The particles of matter are in constant motion: Yes according to kinetic theory the matter particles are in constant motion.
4)The particles of matter have zero kinetic energy: it is not possible.
