It's called an isotope.
isomer
The center of an atom is called a nucleus (nucleifor plural).Center of an atom is called the "Nucleus".
the denser part of an atom is the nucleus. about 99% of the mass of an atom is concentrated within the atom.
Nuetrons are found in the center of an atom which is called the nucleus.
The proton is located in the atom's nucleus, with the neutrons (if there are any).
The nucleus of a helium atom is composed of two protons and two neutrons. Alpha particles have the same composition as the nucleus of a helium atom.
The nucleus of any atom is in the center; the nucleus of krypton has 36 protons and a variable number of neutrons, depending on the isotopes.
The center of an atom is called a nucleus (nucleifor plural).Center of an atom is called the "Nucleus".
the denser part of an atom is the nucleus. about 99% of the mass of an atom is concentrated within the atom.
The nucleus forms the centre of the atom. The protons and neutrons are found in the nucleus of the atom.
The center of an atom is the atomic nucleus.
in the nucleus of the atom
Protons are found in the nucleus of atoms along with the neutrons of the atom. The nucleus is always in the centre of the atom.
Without a nucleus it can not be either an atom or hydrogen.
The nucleus is the central part of the atom. (It's in the center)
the center of an atom is called a nucleus. the nucleus contains the atom's protons and nuetrons.
The atomic nucleus contain protons and neutrons; a nucleus is in the center of the atom and is electrically positive
The nucleus of an atom is made of 'Protons' and 'Neutrons'. The nucleus of an atom is then surrounded by 'Electrons'.
