How many electrons does the Au+ ion have ? Enter an integer below without any letters or symbols.
How many doesn Au element have? That's the same as the number of protons and that's the atomic number in the periodic table. To make it +1 ion you must lose 1 electron.
43 won't do it.
To determine the number of electrons in the Au+ ion, we need to know the atomic number of gold (Au) and the ion's charge. The atomic number of gold is 79.
The charge of the Au+ ion means that it has lost one electron compared to the neutral gold atom. Since a neutral atom of gold has the same number of protons and electrons, the Au+ ion would have one less electron than the neutral gold atom.
Therefore, the Au+ ion would have 79 - 1 = 78 electrons.
