Admin How many total electrons are in the ion Au3+?
Au3+ = 79 protons, 76 electrons d.
How many electrons does a calcium ion have?
18 electrons
Since calcium lost two electrons, it has 20 protons, but only 18 electrons. This makes calcium a positive ion with a charge of 2+. Since each chlorine atom gained an electron, they each have 17 protons and 18 electrons.
How many electron does strontium have?
38 electrons
Strontium has 38 protons (necessarily!), and 38 electrons (necessarily), and has generally 48, 49, or 50 neutrons depending on the isotope.
How many electrons does a potassium +1 ion have?
19
If we got K+ , there must be ONE electron less than 19….and so, formally, potassium has a Noble Gas configuration, 18 electrons in total, isoelectronic with argon…..

Why does potassium have 19 electrons?
It is always constant. (e.g., H=1, K=19, Ur=92). So if you look for potassium (symbol K in the periodic table), you will find that it has the atomic number of 19. This tells you that potassium has 19 protons and – since the number of protons is the same as the number of electrons- also 19 electrons.
