Their instructions are for a sodium atom, but we can adjust them to make a model of any atom.

You will need 40 large balls (20 of one colour for the protons and 20 of another colour for the neutrons) and 20 small balls for the electrons. ...

Cut a small, a medium, a large, and an extra-large ring out of cardstock.

Answer 2

Step 1

You will need 40 large balls (20 of one colour for the protons and 20 of another colour for the neutrons) and 20 small balls for the electrons.

Glue the protons and neutrons into a ball, alternating between protons and neutrons as you go (you can use toothpicks to hold marshmallows together).

Step 2:

Cut a small, a medium, a large, and an extra-large ring out of cardstock.

Use string to tie these rings in concentric circles around the nucleus (the picture below has only three rings for a sodium atom).

Step 3:

Glue two electrons to the small circle, eight to the medium circle, eight to the large circle, and two to the extra-large circle.

Step 4:

Attach string to the outer circle for hanging, and display your 3D model of calcium (the picture below is of sodium).

hope this helps and mark me as brainliest if it does ✌️
