Question

Which of the following is an accurate description of a neutral potassium

(K) atom?
19 particles in the nucleus and 39 particles outside the nucleus
39 particles in the nucleus and 19 particles outside the nucleus
19 particles in the nucleus and 20 particles outside the nucleus
39 particles in the nucleus and NO particles outside the nucleus

Answer 1

39 particles in the nucleus and 19 particles outside the nucleus

Step-by-step explanation:

In the atom of every element, there are three subatomic particles namely; proton, neutron and electron that constitutes the behavior of such an atom. The PROTON and NEUTRON are located inside the nucleus while the ELECTRON is located outside of the nucleus.

For instance, in a neutral pottasium (K) atom i.e. uncharged, there are 19 protons and 19 electrons but 20 neutrons. Note that, mass no. = Proton no. + Neutron no. Based on the explanation of the location of each subatomic particle, it means there are 39 particles in the nucleus (20 neutrons and 19 protons) and 19 particles (electrons) outside the nucleus.
