How many shells does astatine have?
The most commonly created type of astatine has 125 neutrons, with 85 electrons spread among six different shells.
What is the atomic mass of astatine?
The atomic mass of the element Astatine is approximately 210 atomic mass unit
What is the charge of astatine?
Astatine is a diatomic halogen molecule. It I exists as At2, and is a solid at room temperature and pressure. So it has a valence shell of 7 electrons, what’s to gain one more electron to attain stable electronic configuration and octet valance shell structure resembling that of noble gases. Hence it’s charge would be -1, At-.
