What are the bhor models for barlium and alluminum?

Answer 1

I cannot show you, but I can tell you how to make it. Find out how many electrons it has by looking at the atomic number (They ascend in order from Hydrogen, going left to right, up to down). Then draw a small solid circle followed by bigger, empty circles. Draw dots on the circles to represent electrons, and on the bottom note how many neutrons and protons there are in the atom. Then draw the electrons as follows:

Circle 1: 2

Circle 2: 8

Circle 3: 18

Circle 4: 32

Circle 5: 32

Beyond circle 5 I am unsure how many, although few go beyond that point. Hope this helps, and if you need a visual simply search 'Bohr model' on Google and go into images.
