Moscovium-290, the most stable isotope of moscovium (having a half-life of about 0.8 seconds), has 175 neutrons.
An atom of Moscovium (element 115) has approximately 173 neutrons in its nucleus.
Helium has two neutrons and two protons in its nucleus.

The central region of an atom is called the nucleus. The nucleus consists of many neutrons and protons which can form bonds.

The neutrons usually live in the nucleus of stable isotopes. Sometimes these guys go walkabout and leave home to visit other nuclei, especially if they are from an unstable home. If there are too many wandering neutrons in the neighbourhood all hell can break loose! JCF see also: nuclear fission
