Astatine has 125 neutrons
Any element in the halogen group will have seven valence electrons. These elements include fluorine, chlorine, bromine, iodine, and astatine.
In a Lewis dot structure for astatine (At), you would represent it with the chemical symbol "At" and place seven dots around it to represent the 7 valence electrons of astatine. This arrangement helps to show the sharing or transfer of electrons between atoms in a molecule.
Indium has 3 valence electrons.
8 valence electrons- 1s22s2p63s2p6
Fluorine, chlorine, bromine, iodine, and astatine have 7 valence electrons.
