Depending on how particular you want to be, then Hydrogen tends to have an atomic mass of 1.
1 Proton, 0 Neutrons, and a negligible weight for an electron.

No, there is no naturally occurring element with the same atomic number and Atomic Mass. The atomic mass of an element is the weighted average of the masses of its isotopes, which have different numbers of neutrons. The atomic number of an element is the number of protons in its nucleus, which determines its identity. Therefore, the atomic number and atomic mass are different for each element.

Does an isotope of an element have a different atomic mass?
Yes; isotopes of the same element have the same atomic number but differ in their atomic masses.
What do two different neutral isotopes of the same element have in common nuclear number atomic mass nuclear mass atomic number?
The atomic number is the same for all isotopes.
Why do two isotopes of an element have the same atomic number but differnent mass number?
Because the atomic number is the number of protons in an element. If you change the atomic number you will have a completely different element. The mass number changes because the number of neutrons is different.
Can atoms of two different elements have the same atomic number and could they have the same mass number?
The atomic number, or Proton number, defines which element it is. So by definition, two different elements must have a different atomic number, or else they'd be the same element. Atomic mass is the number of protons + neutrons in the element's nucleus. Since the number of neutrons in the nucleus can vary, even within a single element (as isotopes) it is possible to have one isotope of one element sharing an atomic mass with an isotope of another element.
What element has an atomic mass of 4.0?
The predominant isotope of the element helium has a mass number of 4, and the element may have the same mass, to the two significant digits specified, in atomic mass units.
What is the atomic mass the same as?
The Atomic Mass is equal to the number of protons and electrons that an element has.
Does an isotope of an element have a different atomic mass?
Yes; isotopes of the same element have the same atomic number but differ in their atomic masses.
What is the same as the atomic mass number of an element?
Atoms atomic number represents their number of protons.
What are atoms of an element have the same atomic number but a different atomic mass?
isotope
Name the element with the same atomic number and mass number?

Because the atomic number is the number of protons in an element. If you change the atomic number you will have a completely different element. The mass number changes because the number of neutrons is different.
What are the atomic weights of two isotopes of the element number?
both the atomic number and the atomic mass remain the same

Which isotopes of uncharged elements have different numbers?
The isotopes of the same element has the same atomic number. But the mass number (atomic mass) is different.
What element has an atomic mass of 4.0?
The predominant isotope of the element helium has a mass number of 4, and the element may have the same mass, to the two significant digits specified, in atomic mass units.
Are neutrons the same as mass numbers?
No. The number of neutrons is represented by the element's atomic number, not the mass number.
