Could another type of atom just happen to have 11 protons, 11 electrons and 12 neutrons ? No. The number of protons = the 'Atomic Number', which is sometimes referred to as 'Z', defines the type of atom, i.e. which element it is an atom of. As indicated in the List of Chemi...

Elements are classified by the number of protons in the nucleus of the atom. However, there is no set rule for how many neutrons can be in the atom's nucleus. Because this number can vary, we classify the different, naturally occurring, variations of neutron quantities as isotopes of the ...

Current convention defines 1 amu as exactly 1/12 the mass of an atom of the isotope 12C. Since most elements occur naturally in well-established fixed relative abundances of different isotopes, the so-called Atomic Mass for a particular element represents The expected mass for ^{24} O is 2...
A nucleon is a collective term for protons and neutrons inside an atomic nucleus, while the nucleus is the core of an atom, containing nucleons and thus most of the atom's mass.
The number of neutrons is what defines the type of isotope an element it is while the number of protons identifies the type of atom it is. Helium-4, which is the most common isotope of helium has two protons and two neutrons in its nucleus. A common hydrogen atom has no neutrons ...
