34
Selenium has 6 electrons in its outermost shell.
Selenium has 34 electrons.
Selenium typically has 34 electrons in its neutral state. To determine the number of electrons in a selenium ion, you need to know the specific charge of the ion. For example, a selenium ion with a charge of +2 would have 32 electrons, while a selenium ion with a charge of -2 would have 36 electrons.
Neutral selenium has 6 valence electrons.
Selenium is Atominc number: 34 It has 6 Valence electrons Therefore you take 6 from 34: 28 core electrons
Selenium has 6 valence electrons. It belongs to group 16 of the periodic table, so it has 6 electrons in its outermost energy level.
No, Selenium has 6 valence electrons while Bromine has 7. You can determine this because on the periodic table, Selenium is in Group VI while Bromine is in group VII.
Selenium would not have the same number of valence electrons as the others. Boron, aluminum, and gallium all have 3 valence electrons, while selenium has 6 valence electrons.
Selenium has 6 valence electrons
Atomic number= No. of electrons in the atom. Atomic no. of selenium=34. Therefore,selenium has 34 electrons in each of its atom.
Selenium needs two more electrons.
Selenium can gain 1 electron or loss 2, 4, 6 electrons.
