The atomic mass of an element, such as hydrogen, does not affect its name. The name of an element is determined by its atomic number, which is the number of protons in its nucleus. The atomic mass of an element can vary slightly due to the presence of different isotopes, which have varying numbers of neutrons.
Hydrogen, with an atomic number of 1, is the lightest and simplest element in the periodic table. It typically has an atomic mass of approximately 1.008 atomic mass units (amu) due to the presence of its most abundant isotope, hydrogen-1 (also known as protium).
If, hypothetically, the atomic mass of hydrogen were to change significantly, it would still be called hydrogen. The name of an element remains constant regardless of any changes in its atomic mass.
