What is the mass symbol for hydrogen atom?

The mass symbol for a hydrogen atom is represented by Mh. This designation is derived from the chemical symbol for hydrogen, which is "H," combined with the symbol "m" that denotes mass. The hydrogen atom, being the simplest and lightest element, has a relatively low atomic mass that reflects its fundamental nature in both chemistry and physics.

Understanding this can be important, as it underscores how mass symbols are often consistent in reflecting the element’s chemical symbol along with denoting mass, which is a standard convention in scientific literature. Other symbols provided in the options do not conform to this established naming convention for atomic mass symbols and represent different entities or are nonsensical in this context.
