how many element, protons, neutrons, electrons, Atomic number, mass number and charge does Gold (Au) have​

It is gold (Au) since it has 79 protons (the charge number of 79) and it has 118 neutrons (197 - 79 = 118).

Explanation:

hope it helps u sis can I get branliest pls if possible

fe 55.85 g/mol and h2o 18.02 g/mol.

metals are good conductor of electricity. it has free electrons on their surface. according to electron pool theory, each atom present in a metal crystal losses all of its valence electron and as a result a pool of free is form. these pool of electrons are free to move and   conduct electricity easily   while making metal as good conductor.

the correct answer is a. the ability of electrons to flow throughout the metal.
