Write the chemical symbols for three different atoms or atomic anions with 35 electrons.

Bromine atom, Br has 35 electrons
In Se there are 34 electrons and if it gain one electron and get negative charge  then it has 35 electrons. So the symbol of anion wit 35 electrons is
Se⁻ has 35 electrons
Another anion, no longer solid as quickly as back is  As²⁻
As has 33 electrons and the two negatives shows now it has 35 electrons.

The chemical symbols of the species with 35 electrons has been , and .

The element with the 35 number of electrons has been Bromine. It has been a Halogen of group 17.

To attain a specific number of electronic configurations, the atoms gain or lose electrons.

By gaining electron a -ve charge is added, and by losing electron a +ve charge is added.

Se has 34 electrons by gaining an electron the number of electrons will be 35. The symbol will be .As has 33 electrons, by gaining 2 electrons the number of electrons will be 35. The symbol will be .Kr has 36 electrons, by losing an electron the of electrons will be 35. The symbol will be .

The chemical symbols of the species with 35 electrons has been , and .
