WebJan 31, 2014 · Along with the four protons, the collision-induced reactions had removed anywhere from six to 15 neutrons, producing a range of gold isotopes from gold 190 (79 protons and 111 neutrons) to gold ... WebLead is a chemical element with atomic number 82 which means there are 82 protons in its nucleus. Total number of protons in the nucleus is called the atomic number of the atom … WebWe can also assume that it has 8 electrons. So, oxygen has eight positive particles plus eight negative particles. Think of this as 8+(-8) or 8-8. Eight minus eight equals zero, which is neutral. Basically, a "neutral atom" is an atom that has the same amount of protons as it does electrons. Later you will learn about ions, which have unequal ... high ph number
