Answer:
atoms in which number of protons equals number of atoms
those atoms whose atomic mass is exactly double the atomic number
as
atomic number = no. of protons
atomic mass = no. of protons + no. of neutrons
so if protons equals neutron
atomic mass becomes twice atomic number.
example= He (helium)
