Moscovium

Atomic number 115 means that every Moscovium nucleus contains 115 protons. That proton count is the element's identity: change it and you no longer have Moscovium.

Start with the nucleus

Atomic number 115 means that every Moscovium nucleus contains 115 protons. That proton count is the element's identity: change it and you no longer have Moscovium.

Moscovium (Mc) is chemical element 115. It belongs to the post-transition metals, and its reference state at room temperature is not firmly established. Those basic facts are a useful starting point for its chemistry and applications.

In practice, it turns up most often in scientific research.

Understanding the element

Moscovium (Mc) is chemical element 115. It belongs to the post-transition metals, and its reference state at room temperature is not firmly established. Those basic facts are a useful starting point for its chemistry and applications.

Where do we encounter it?

In practice, it turns up most often in scientific research.

What its position in the table tells us

Moscovium sits in period 7, group 15 and the P block. That location is useful because neighbouring elements often share trends in valence electrons, oxidation states and bonding behaviour.
