Protons, neutrons and electrons in Moscovium
A neutral Moscovium atom has 115 protons and 115 electrons. Most Moscovium atoms have about 175 neutrons: the atomic mass rounded to 290, minus the atomic number 115.
Neutrons are approximate: atoms of the same element can have different numbers of neutrons (isotopes). Atomic number and mass
How many valence electrons does Moscovium have?
5
Moscovium has 5 valence electrons in its outermost shell, shell 7. These are the electrons involved in chemical bonding.

- Before it was named, element 115 was known by the temporary systematic name ununpentium.
- Moscovium (Mc) has atomic number 115. It was discovered in 2003.
Position in the periodic table
Moscovium is element 115, in period 7 and group 15 of the periodic table, in the p-block.
Uses of Moscovium
Moscovium has no uses outside research because only a small number of atoms have been made, each decaying in less than a second. Scientists study its long chains of alpha decays, which pass through nihonium, roentgenium and lighter elements, to learn about the structure and stability of superheavy nuclei.
Who discovered Moscovium?
A team led by Yuri Oganessian at the Joint Institute for Nuclear Research in Dubna, Russia, working with Lawrence Livermore National Laboratory, first made moscovium in 2003 by bombarding americium with calcium ions. It is named after the Moscow region, where Dubna is located.
Where does the name come from?
Moscovium is named after the Moscow region of Russia, where the Joint Institute for Nuclear Research in Dubna is located. Russian and American scientists working together first produced the element in 2003.

How many protons, neutrons and electrons does Moscovium have?
A neutral Moscovium atom has 115 protons and 115 electrons. Most Moscovium atoms have about 175 neutrons: the atomic mass rounded to 290, minus the atomic number 115.
How many valence electrons does Moscovium have?
Moscovium has 5 valence electrons in its outermost shell, shell 7. These are the electrons involved in chemical bonding.
What is the molar mass of Moscovium?
The molar mass of Moscovium is 290 g/mol. This is the same number as its atomic mass, 290 u.
Is Moscovium a metal?
Moscovium is a synthetic superheavy element, so too few atoms have been made to measure whether it behaves as a metal.
Is Moscovium radioactive?
Yes. Moscovium has no stable isotopes, so all of its atoms are radioactive and eventually decay into other elements.
Where is Moscovium on the periodic table?
Moscovium is element 115, in period 7 and group 15 of the periodic table, in the p-block.
