Asingle adam of an element has 11 protons 11 electrons and 12 neutrons which element is it?

Assuming you mean atom, the element with the atomic number of 11 is sodium (Na). You could also figure it out by its atomic weight - that is, protons plus neutrons. That's 11+12, which is 23, which is relatively close to sodium's 22.99

sodium, you can find the element by it's protons sense all the elements are in order my number
