Tellurium Valence Electrons
Why tellurium has 6
Tellurium has 52 electrons, arranged as 1s2 2s2 2p6 3s2 3p6 3d10 4s2 4p6 4d10 5s2 5p4. The highest shell is n = 5, holding 5s2 5p4, so 2 + 4 = 6.
Tellurium is in group 16; for groups 13–18 subtract 10 from the group number.
What that means for bonding
Tellurium needs 2 more electrons to complete an octet, so it tends to gain 2 (forming Te2−) or share 2 in 2 covalent bonds.
Electrons per shell: 2, 8, 18, 18, 6. See the tellurium electron configuration and orbital diagram or the full tellurium data sheet.

Tellurium valence electrons FAQ
How many valence electrons does tellurium have?
Tellurium has 6 valence electrons. Its electron configuration is 1s² 2s² 2p⁶ 3s² 3p⁶ 3d¹⁰ 4s² 4p⁶ 4d¹⁰ 5s² 5p⁴, and the outermost shell (n = 5) holds 5s² + 5p⁴.
How do you find the valence electrons of tellurium?
Tellurium is in group 16; for groups 13–18 subtract 10 from the group number.
How many bonds does tellurium form?
Tellurium needs 2 more electrons to complete an octet, so it tends to gain 2 (forming Te2−) or share 2 in 2 covalent bonds.
What is the Lewis dot structure of tellurium?
The symbol Te with 6 dots around it, one per valence electron, placed singly on each side before any side is paired.
How many core electrons does tellurium have?
46: 52 electrons in total minus the 6 valence electrons.
