Which subatomic particle has a negative charge

The electron

Explanation:

The atom consists of three subatomic particles:

- The proton: protons are inside the nucleus of the atoms, they have positive charge of +e (), and a mass of approximately

- The neutron: neutrons are also located inside the nucleus of the atoms, they have no electrical charge and mass similar to the mass of the proton

- The electron: electrons orbit around the nucleus in a cloud, they have negative charge of -e (), and their mass is about 1800 time smaller than the mass of the proton ()

its c its is a mixture of gases

the temperature and the pressure affect solubility. temperature affects by changing the properties of the solvent. the increase in pressure increases solubility, the decrease in pressure decreases solubility.
