Yes they all have except Hydrogen. H has only one proton in its nucleus.
Atoms have a Nucleus, Protons, Nuetrons, Electrons!
Protons, nuetrons, and electrons
quark
the protons and nuetrons keep the atoms maintained. easy
it is about 68 to 69 depending on the atoms atomic mass
They are called isotopes.
An isotope.
There are 2 neutrons in a helium atoms nucleus , along with two protons.
Is called an Isotope.
16 - 8 = 8.
No they are negatively charged, nuetrons are nuetral, protons are positive, not all atoms have nuetrons
An element can be identified by the number of protons in the nucleus of its atoms.
