Question

(Help please!!! important question!!!) A neutral atom has an atomic number of 20 and a mass number of 41; how many protons, neutrons, and electrons are found within the atom? (2 points) 21 protons 21 electrons and 20 neutrons, 20 protons 20 electrons and 21 neutrons, 1 protons 20 electron and 20 neutrons, 41 protons 41 electrons and 20 neutrons

Answer 1

Answer: 20 protons,20 electrons and 21 neutrons

Explanation: because the number of protons is the same as the atomic number, and if the atom is neutral it has the same number of protons and electrons. if the mass number is 41 it means that there are 21 neutrons because to find the mass number you have to add protons and neutrons, so 20 + 21 = 41 and to confirm it the neutrons have been subtracted from the mass number and the atomic number, so 41-20 = 21
