atoms have symbols so that the atoms of different elements can be distinguished easily.
because they are different
Atoms of the same element that have different masses are called isotopes of the element. The presence of different numbers of neutrons in the nucleus is responsible for the existence of isotopes of an element.
for each element the atoms are different
All elements are composed of atoms that all have the same atomic number. If the atomic number is different then you have a different element. The number of neutrons can be different and you will have a different isotope of that element with a different mass. An example of an element that only has one isotope is fluorine.
Atoms have isotopes: it is true, the isotopes of the same element have different number of neutrons.
That would be subscript.
Each element is different so for a certain element to be define/determined it has different atoms to make it up so no other element has the same atoms

Yes, the element changes to compound when atoms of it changes because compound is made up of different types of element and the element is made up of different types of atoms when the atoms are changed the element also changes and different types of elements are made due to this the element is changed to a compound.
Atoms of the same element differ in the number of neutrons in their nuclei. All atoms of a given element have the same number of protons, of course. The number of protons in a nucleus determines which element the atom is. But the number of neutrons can vary, and these different "versions" of a given element are called isotopes of that element. See the related question, which is linked below.

The number of electrons and neutrons may differ for atoms of the same element. However, what distinguishes atoms of one element from those of a different element is the number of protons in the atom's nucleus. All of the atoms of an element have the same number of protons, which is the single most important determiner of the properties of an element.
Yes, an element is made of millions of atoms with the same number of protons and electrons, but some atoms will have a slightly different number of neutrons. These different atoms are called isotopes.
chemical formula
Yes, atoms of different elements have a different number of protons.
