WebGold atoms have 79 electrons and 79 protons with 118 neutrons in the most abundant isotope. Under standard conditions gold is a shiny yellow metal. It is very dense and heavy, but also fairly soft. Gold is the most malleable of the metals meaning that it can be pounded into a very thin sheet.

WebElements have families as well, known as isotopes. Isotopes are members of a family of an element that all have the same number of protons but different numbers of neutrons. The number of protons in a nucleus determines the element’s atomic number on the Periodic Table. For example, carbon has six protons and is atomic number 6. WebForms of the same atom that differ only in their number of neutrons are called isotopes. Together, the number of protons and the number of neutrons determine an element’s mass number: mass number = protons …
