Neutrons and protons combined
Atomic weight/ mass = number of protons + number of neutrons
In an uncharged atom, the number of electrons is always equal to the atomic number, in this instance, 9.
The number of protons in an atom is equal to its atomic number.
the units for atomic weight are grams per mole. your question cannot really be answered correctly.
In a neutral atom the number of protons is equal to the number of electrons. And by definition the atomic number of an atom is equal to the number of protons in it. So the atomic number of a neutral atom is equal to the number of protons or the number of electrons in the atom.
Atomic weight/ mass = number of protons + number of neutrons
atomic weight = mass of protons + mass of neutrons
If you add the number of protons to the number of neutrons in an atom, you have calculated that atom's atomic mass.
In an uncharged atom, the number of electrons is always equal to the atomic number, in this instance, 9.
It is called the atomic no. of element. It is also equal to the no. of electrons in the atom.

The number of protons is equal to atomic number; in a neutral atom the number of electrons is also equal to the numbers of protons.
An atom of oxygen has twice the weight of an atom of nitrogen since the atomic weight of nitrogen is around 14 amu (atomic mass units), while the atomic weight of oxygen is around 16 amu.
Atomic Number :- atomic number of an element is the number of protons present in the nucleus of the atom. (since atoms are electrically neutral the number of protons in an atom is equal to the number of electrons in an atom) Atomic Mass :- atomic mass of an element is the number which tells us how many times an atom of that element is heavier than an atom of hydrogen (whose atomic weight is taken as unity [1])
