The number of neutrons present in the atom.
Neutrons
All are indispensable; only the isotope 1H hasn't a neutron.
Neutron
All the isotopes of chemical elements contain protons, neutrons and electrons.
No. All atoms, except the most abundant isotope of hydrogen, can be divided into the subatomic particles protons, neutrons, and electrons. The most abundant hydrogen isotope does not have neutrons.
There are many elements that have only one naturally occurring isotope. When you get to transuranic elements the elements all have no naturally occurring isotopes. But all elements have isotopes, they just have to be created, maybe in a nuclear reactor or particle accelerator or a supernova explosion.
The number of neutrons is different for each isotope.
neutron
isotope.
The number of neutrons is different for each isotope.
All the atoms of chemical elements contain protons, neutrons and electrons. Only one exception: the isotope protium 1H hasn't a neutron.
The number of neutrons is different for each isotope.
All are indispensable; only the isotope 1H hasn't a neutron.
The isotope hydrogen-1 don't contain neutrons.
Isotopes differ each other from the number of neutrons which is a chemically inert subatomic particle.
Neutron
Silicon has 14 electrons and protons; the number of neutrons is specific for each isotope. Number of neutrons in a silicon isotope = Mass number - 14
Boron has 5 electrons and protons; the number of neutrons is specific for each isotope. Number of neutrons in a boron isotope = Mass number - 5
