1. Una propiedad de la materia es que posee masa, y en el átomo no hay excepción a pesar de su tamaño infinitamente pequeño. Cuando la masa atómica de un elemento se expresa en gramos, se obtiene una magnitud denominada:​

they absorb it i think

not sure

you

the relative atomic mass of an element is the mass of one atom of that element, relative to 1/12th of the mass of a  1212c atom. to convert to an absolute mass in kg, it is necessary to multiply by  1.661×10−271.661×10−27.

the relative atomic mass is roughly equal to the number of neutrons, plus the number of protons, in the nucleus of the atom.

for elements with more than one stable isotope (different types of nucleus with different numbers of neutrons but the same number of protons), the quoted mass is usually the average mass, weighted by the relative abundance of the different isotopes.

what exactly is the question lol
