Is cl2 positive or negative?
Answer. is nothing but a Chlorine molecule made up of two Chlorine atoms with one negative charge on each. The resultant chlorine molecule or is neutral in charge as the two form covalent bonding. Thus they have no charge as either of the two atoms has not lost or gained any electrons.
Is Silver positive or negative charge?
The electro colloidal silver atom (Ag+1), is an ion of the natural silver atom (refer Fig. By losing one electron, the atom now has only 46 negatively charged electrons in total, and the centre of the atom still has a positive charge of 47. As a result, the overall charge of the entire atom is now positive (Ag+1).
