Sulfur is a non-metal with an Atomic Mass of 32 amu
No two elements may have the same atomic number. But two elements may have same atomic mass. Hence atomic number is better than atomic mass.
The element with an atomic mass of 4.0 is helium. Helium has an atomic number of 2, which means it has two protons in its nucleus. It also has two neutrons, giving it an atomic mass of 4.0.
Naturally occurring lithium contains two isotopes. The common one has an atomic mass of 7. About one per cent of the lithium has an atomic mass of 6.The atomic mass of Lithium-Li is 6.941 grams.
The atomic mass of a helium atom is approximately 4 atomic mass units (amu). This value reflects the combined mass of its two protons and two neutrons, as helium has two protons in its nucleus and typically two neutrons. The mass of electrons is negligible compared to that of protons and neutrons, so it does not significantly affect the atomic mass. Thus, the expected atomic mass aligns closely with the sum of the nucleons in the helium nucleus.
only one element (hydrogen) has the atomic mass of 1.

The number of protons and neutrons in the atom can be determined from the atomic mass. The atomic mass represents the average mass of the isotopes of that element in atomic mass units.
Each element on the periodic table has two numbers: the atomic number and the relative atomic mass. The atomic number is the number of protons in the nucleus, and the relative atomic mass is the total number of protons and neutrons (so the difference between them is the number of neutrons). The relative atomic mass is always the higher of the two.
Not generally. For light elements this relation is often approximately true, but for heavier elements, the gram atomic mass is more than two times the atomic number, as the ratio of neutrons to protons increases with increasing atomic mass.
Lithium is a meta element. Atomic mass of it is 7.
The same as for a helium nucleus: 4. Two protons and two neutrons.
No, atomic mass and atomic diameter are not the same thing. Atomic mass refers to the mass of an atom, which is the sum of the protons and neutrons in the nucleus, while atomic diameter refers to the size of the atom, often measured as the distance between the nuclei of two bonded atoms.
