Chemistry insights 'O' level
Hydrogen, with just one proton has a proton number of 1 . Lithium, with three
protons, has a proton number of 3. The proton number of uranium (symbol U) is
92, meaning that an atom of uranium has 92 protons. Each element has its own ...

Advanced Physics Through Diagrams
If the number of neutrons (A - Z) in the nucleus is plotted against the number of
protons (Z) for all known nuclides, the general form of the graph is like this: 140
40 60 80 100 proton number (Z) Stable nuclides These have nuclei which are ...

An atom's proton number, symbol Z, is the number of protons in an atom. In a
neutral atom, the number of protons in the nucleus is equal to the number of
electrons round the outside. All the atoms of a particular element have the same
proton ...

The number ofprotons in the nucleus of an atom is called the proton number (Z). It
is also known as the atomic number. Every atom of the same element has the
same number of protons in its nucleus. It is the proton number that makes an
atom ...

For example, an atom of lead has 82 protons but 125 neutrons. The number of
protons in an atom is called the proton number (also called the atomic number).
Each element has its own proton number. For example, carbon has proton
number ...
Mrs Jacqueline Hilary Briggs, Pearson Education, Limited, 2007
The number of protons (which is also the number of electrons) is called either the
atomic number or the proton number. You can see that Number of neutrons =
Mass number Atomic (proton) number For example, an atom of potassium has a ...

Grand Unification of a 2 Photon Universe
This latter number is ascertained by subtracting the bottom proton number (11)
from the top number (24), which is the addition product of the proton number (11)
and the neutron number (13). This sodium atom is unstable and subject to ...
Proton. Number. The number of protons in an atom is called the proton number (

Express Chemistry Form 4:
For example, if a neutral atom has the proton number of eight, the first shell will
accommodate two electrons and the remaining six will go into the second shell.
Hence, the electron arrangement is 2.6. 8. shell are known as valence electrons.
