Question

how to draw the diagram of atom of oxygen and carbon

Answer 1

This is from 9th standard science textbook

Answer 2

This year, I’ve been basing my introduction to basic chemistry for my middle school students around the periodic table of the elements. The first step, however, is to teach them how to draw basic models of atoms.

Prep: Memorization over the Winter Break

I started it off by having the students memorize the first 20 elements (H through Ca), in their correct order — by atomic number — over their winter break.



A diagram of an oxygen atom.

So that they’d have a bit of context, I went over the basic parts of an atom (protons, neutrons, and electrons) and made it clear that the name of the element is determined solely by the number of protons. I even had them draw a few atoms with the protons and neutrons in the center and the electrons in shells. Since I’d dumped all of this on them in a single class period, it probably was a bit much, but since it was just to give them some context I did not expect the 7th graders, who had not seen this before, to remember it all; for the 8th graders it should have been just a review.

Most students did a good job at the memorization. Some found songs on the the internet that helped, while others just pushed through. Having the two weeks of winter break to work on it probably helped too.
