In what physical state does chlorine exist at -65 c?

The chemical and physical properties of chlorine. In ordinary conditions, chlorine is a yellow-green gas, with a density exceeding the density of air by 2.5 times. The melting temperature of chlorine in a solid state is -100.98 degrees Celsius, and its boiling point is -33.97 degrees Celsius.

nacl or sodium chloride is an ionic compound. this is because an ionic compound pertains to a compound that consists of positively and negatively charged ions. in this case, na (sodium) has a tendency to lose one electron when it reacts with with other atoms, so the resulting sodium ion contains 11 protons and 10 electrons, thus making it positively charged (na+), when chlorine reacts, it usually gains one electron to form an ion called chloride, thus making it negatively charged ( since the ions are oppositely charged, they attract.
