The atomic number is 79.
The mass number of Gold is 197.
79 is the atomic number of gold.
AnswerGoldYou can find this on the periodic table of the elements. The element with atomic number 79 is gold, Au.
The mass number of gold is 197. This number represents the total number of protons and neutrons in the nucleus of a gold atom.
Gold (Au) has a mass of 196.96655 amu. Actually the mass number if gold is dependent on the number of neutrons in the mix. Gold has 79 protons and the isotope that gold is at the time will determine the mass number. So, mass number = # of protons + # of neutrons...this is for any element.
Gold is a metal element. Atomic number of it is 47.
Gold's atomic number is 79, which means that every gold atom has 79 protons in its nucleus.
Gold has 118 neutrons.
Gold (Au) has 79 protons in its nucleus. The number of neutrons in gold can vary depending on the isotope. The most common isotope of gold, gold-197, has 118 neutrons.
The atomic symbol for gold is Au and its atomic number is 79.
Gold has 79 electrons and protons; the number of neutrons is specific for each isotope. Number of neutrons in a gold isotope = Mass number - 79
no, gold does not always need a number on it. most gold pieces don't, some like rings and other few thing might have a number saying how much karates it has but it can still be real gold if it doesnt have a number. :)
