Alpha decay release a helium nucleus (2 protons and 2 nutrons).
Helium does not form compounds because of the electrons doesn't attract to nutrons Helium does not form compounds because the outer (only) shell of electrons is full. This is the valence shell, and in order for elements to form compounds, the valence shell must have available slots. Helium does not have any available slots in the valence shell, hence its inability to form compounds.
Chlorine typically has 18 neutrons in its nucleus, which accounts for its atomic weight of 35.45 g/mol.
Helium-4 has 2 electrons.
A neutral atom of helium has 2 electrons.
Not sure about nutrons, but xenon has between 70 and 82 neutrons.
mercury has 121 nutrons because the periodic table
Radium has 88 neutrons.
Typically, 69. However it can vary by isotope.
Einsteinium typically has 99 neutrons in its nucleus.
7 is most common. It can also be 6 or 8.
