Polonium Valence Electrons
Why polonium has 6
Polonium has 84 electrons, arranged as 1s2 2s2 2p6 3s2 3p6 3d10 4s2 4p6 4d10 5s2 5p6 4f14 5d10 6s2 6p4. The highest shell is n = 6, holding 6s2 6p4, so 2 + 4 = 6.
Polonium is in group 16; for groups 13–18 subtract 10 from the group number.
What that means for bonding
As a metal, polonium tends to lose valence electrons rather than gain them, forming Po2+ or Po4+ ions. Heavy p-block metals often keep their outer s pair and lose only the p electrons (the inert pair effect), which explains the lower charge.
Electrons per shell: 2, 8, 18, 32, 18, 6. See the polonium electron configuration and orbital diagram or the full polonium data sheet.

Polonium valence electrons FAQ
How many valence electrons does polonium have?
Polonium has 6 valence electrons. Its electron configuration is 1s² 2s² 2p⁶ 3s² 3p⁶ 3d¹⁰ 4s² 4p⁶ 4d¹⁰ 5s² 5p⁶ 4f¹⁴ 5d¹⁰ 6s² 6p⁴, and the outermost shell (n = 6) holds 6s² + 6p⁴.
How do you find the valence electrons of polonium?
Polonium is in group 16; for groups 13–18 subtract 10 from the group number.
How many bonds does polonium form?
As a metal, polonium tends to lose valence electrons rather than gain them, forming Po2+ or Po4+ ions. Heavy p-block metals often keep their outer s pair and lose only the p electrons (the inert pair effect), which explains the lower charge.
What is the Lewis dot structure of polonium?
The symbol Po with 6 dots around it, one per valence electron, placed singly on each side before any side is paired.
How many core electrons does polonium have?
78: 84 electrons in total minus the 6 valence electrons.
