no, atoms don't have to have neutrons, neutrons are supposed to be neutral so it wont change the charge of the atom if you add or subtract neutrons from an atom. what will change is the mass number of the atom.
The atoms of ALL elements contain at least one protons. The atomic number of each element is a count of how many protons atoms of that element contain. Thus, in answer to your question, there are NO metals that do not contain a proton.
Most hydrogen atoms don't contain any neutrons. Deuterium atoms are hydrogen atoms with one neutron each, and tritium atoms are hydrogen atoms with two neutrons each, but most hydrogen atoms are protium atoms, with no neutrons at all. All other atoms in the universe except protium contain at least one neutron each.
All the lithium atoms contain the same number of protons.
All matter is made of atoms.
Amines all contain nitrogen atoms. They are organic compounds derived from ammonia where one or more hydrogen atoms are replaced by alkyl or aryl groups.

All other atoms in the universe except protium contain at least one neutron each.
The basic building block of all compounds is atoms. Compounds contain atoms of at least two different elements bonded to one another. Thus, atoms of elements are what form compounds.
All organic molecules contain carbon atoms.
All the lithium atoms contain the same number of protons.
The commonalities that elements, compounds, and mixtures all have in common is that they all contain atoms. Even though they all contain atoms, the number of atoms vary in each of them.

All matter is made of atoms.
All atoms of sodium must contain 11 protons in their nucleus.
All atoms of an element have the same number of protons and electrons (in the neutral state).
yes
