How many electron, protons , and neutrons does gold have? how many protons, electrons, and neutrons are in an atom of gold?

Why are the trends and exceptions to the trends in ionization energy observed?

May someone me with these science questions

Given the following information: mass of proton = 1.00728 amu mass of neutron = 1.00866 amu mass of electron = 5.486 × 10^-4 amu speed of light = 2.9979 × 10^8 m/s calculate the nuclear binding energy (absolute value) of 3li^6. which has an atomic mass of 6.015126 amu. j/mol.
