The number of protons.
The number of protons in the nucleus never changes in a neutral atom. This is because the number of protons determines the element's identity.
The atomic number
The number of protons it has in the nucleus. Number of electrons and neutrons can vary but if the number of protons changes, you have a different element. Number of protons is a constant in an element which never changes.

Argon gas is an element. It will be element only. It can be part of some mixture. But never ever be a part of the compound. It is a noble gas.

The sugar and phosphate group of nucleotides never change. There are four possible nitrogenous bases and thus it is the only part of nucleotides that can change.
The atomic number and mass number of an element never change when it becomes part of a compound. These values are unique to each element and are constant regardless of its chemical state.
Its protons. The atom changes depending on how many protons it has. See also atomic number.
yes, it usually is, the number of protons never changes is in an atom, the amount of neutrons and electrons do however.
No you can't save the changes in inspect element. The changes have to be made in the original source code.
