Protons and neutrons, except in hydrogen which has just one proton.
The atomic number of an element is equal to the number of protons contained in the atomic nucleus.
Atomic Number is the amount of Protons (positively charged subatomic particles) contained in the nucleus of an atom.
Proton: positive charged particle, contained in atomic nucleus, mass=approx. 1 u Neutron: neutral particle, contained in atomic nucleus, mass=approx. 1 u Electron: negative charged particle, component of an atom (but not contained in nucleus), mass=approx. 1/1836 from the mass of a proton.
The non-charged particles contained in the nucleus of an atom are called neutrons. Neutrons, along with protons (which are positively charged), make up the atomic nucleus. Together, these particles determine the atomic mass of an element and play a crucial role in the stability of the nucleus. Neutrons do not carry an electric charge, which distinguishes them from protons.
The cathodic rays beam was deflected by the atomic nucleus.
None. All elements have a unique atomic number designated by the number of protons contained in their nucleus.
The number of protons in the nucleus of an element gives that element its ATOMIC NUMBER.
That would be the Atomic number. It tells you how many protons are contained in the nucleus of an atom. No two elements could share this number.
Eukayotic cells have a contained nucleus
The atomic number is the number of protons in a nucleus.
Chromatin material is contained within the nucleus.
The atomic nucleus contain protons and neutrons; these particles are formed from quarks and gluons.
