How can you find the number of electrons in aluminum 26?
the electrons is the same as the number of protons if the element is neutral… and since there is no charge i would assume it is neutral the 26 refers to the mass number, so protons + neutrons = 26 the number of protons never changes, according to the periodic table of elements, Al has 13 protons (just look at it’s atomic number, same as # of proton) so 26 mass number – 13 protons = 13 neutrons and since we have 13 protons, we have 13 electrons i would still say that the atomic number is 13, i don’t think that changes in isotopes (which is what we have by the way, isotopes are elements that have a different number of neutrons than indicated in the periodic table) hope that helps!
