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 ...

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.
