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.
Electrons per shell in astatine: 2, 8, 18, 32, 18, 7.

The halogen that will have its outer energy level filled with 2 electrons is astatine (At). Halogens typically have seven valence electrons, but astatine is a heavier element that can form stable compounds where it can exhibit a +1 oxidation state, effectively allowing it to achieve a filled outer shell in certain contexts. However, it's important to note that in its elemental form, astatine, like other halogens, primarily exists with seven valence electrons.
Indium has 3 valence electrons.
