Question

Draw a model of a helium-4 atom. Show the number and relative position of protons, neutrons and electrons in your model

Answer 1

Answer #1

Helium has atomic number 2, so it has 2 electron and 2 protons, and it has mass number 4 amu, so it has 2 neutrons.

So, atomic model of He would be like:
