Atoms are electrically neutral because they have equal numbers of protons (positively charged) and electrons (negatively charged).
The color, shape, volume, mass, etc.
True, for example, hydrogen peroxide (liquid):
H₂O₂ + H₂O ⇄ H₃O⁺ + HO₂⁻
HO₂⁻ + H₂O ⇄ H₃O⁺ + O₂²⁻
(the resulting solution is weakly conducting)
The aggregation state, or state of aggregation, is the form of the substance in different kinds of states. For example, Bromine could occur as solid, liquid or gas. For all these forms, its molecular aggregation is diatomic in nature. It is always written as Br₂.
