Moscovium (Mc)
Element 115 · post-transition metal · group 15, period 7
Moscovium is element 115, a post-transition metal in group 15 and period 7. Its electron configuration is [Rn] 5f14 6d10 7s2 7p3. That leaves 5 valence electrons in the outer shell, with the shells filling 2, 8, 18, 32, 32, 18, 5. Its outer shell is already full, so it does not normally form ions at all.

Moscovium Lewis dot structure
Moscovium has 5 valence electrons, so its Lewis symbol carries 5 dots: one pair and three single dots. The dots go one to a side before any of them pair up, so the unpaired ones show exactly how many bonds the atom tends to form.

Electron configuration of moscovium
Orbitals fill from the lowest energy upward. Writing that out for moscovium gives 1s2 2s2 2p6 3s2 3p6 3d10 4s2 4p6 4d10 4f14 5s2 5p6 5d10 5f14 6s2 6p6 6d10 7s2 7p3, which is 1s2 2s2 2p6 3s2 3p6 3d10 4s2 4p6 4d10 4f14 5s2 5p6 5d10 5f14 6s2 6p6 6d10 7s2 7p3 in plain text.
Everything up to Rn is the same as in that noble gas, so it is usually abbreviated to [Rn] 5f14 6d10 7s2 7p3. The part outside the bracket is what does the chemistry.

Moscovium ion charge
Moscovium has no known ions. It is made a few atoms at a time and decays within seconds, so its chemistry has barely been measured. Its position in group 15 suggests how it might behave, but a charge extrapolated from the group would be a guess, not a measurement.
Common questions
What is the Lewis dot structure of moscovium?
The symbol Mc with 5 dots, one for each valence electron: one pair and three single dots. Dots go one to a side before any pair up, the same way electrons fill separate orbitals before sharing one.
How many valence electrons does moscovium have?
Moscovium has 5 valence electrons. For a main-group element the count is the group number minus 10, and moscovium is in group 15.
What is the electron configuration of moscovium?
1s2 2s2 2p6 3s2 3p6 3d10 4s2 4p6 4d10 4f14 5s2 5p6 5d10 5f14 6s2 6p6 6d10 7s2 7p3, or [Rn] 5f14 6d10 7s2 7p3 written from the previous noble gas. Orbitals fill lowest energy first.
How many protons, electrons and neutrons does moscovium have?
A neutral moscovium atom has 115 protons and 115 electrons. Its standard atomic weight is 290, so the most common isotope has about 175 neutrons.
