The atomic number of an element refers to the number of protons in its nucleus. For oxygen (O), the atomic number is 8. So in O2 (oxygen molecule), each oxygen atom contributes its atomic number (8) to the total atomic number for the molecule.
The general trend observed is that as atomic number increases, atomic mass also increases. This relationship is due to the fact that atomic number corresponds to the number of protons in an atom's nucleus, which in turn contributes to its mass.
An atom's atomic number is determined by the number of protons in its nucleus, which are positively charged. The mass number is the sum of the protons and neutrons in the nucleus, as neutrons contribute to the atom's mass but not its charge.
The atomic number is the number of protons in the atom (this can never change). The mass number is the number of protons plus the number of neutrons, this varies because atoms lose neutrons so they take one mole (6.0223x10^23) of the atoms, and average it.
Each nucleon (proton or neutron) contributes about 1 atomic mass unit to the mass of the atom. The mass contribution of the electrons can be ignored, since it takes about 1800 of them to equal the mass of a nucleon and the heaviest elements known have around 1/15th that number of electrons. So if you subtract the atomic number (number of protons) from the atomic mass rounded to the nearest whole number (number of nucleons), what's left is the number of neutrons.
this elemnt has an atomic number that is double the atomic number of silicon?
the answer is that it is called a atomic number.
The atomic number is equal to the number of the protons in the atomic nucleus.
The element with an atomic number that is double the atomic number of silicon is germanium, with an atomic number of 32. Silicon has an atomic number of 14.

Subtract the atomic number from the atomic weight.
