when you wonder what the earth,sky or ocean is made of, you are thinking about chemistry. when you wonder a rain puddle dries up, how a car gets energy from gasoline, or how your body gets energy from the food you eat, you are again thinking about chemistry. —Preceding unsigned comment added by 99.181.102.46 ( talk) 00:28, 4 April 2009 (UTC)

Wikipedia is a "free encyclopedia that anyone can edit". It is available to people all over the world. But why is it so hard to read some pages? I'm a 6th grader, but still, there is just too much technical jargon for this to be helpful for my homework. Can someone please simplify this? -Nathan — Preceding unsigned comment added by 76.24.133.63 ( talk) 21:32, 20 November 2013 (UTC)

In the first paragraph, the phrase "as of the nucleus as of the whole atom or ion" appears. [Edit by user 2a00:23c4:7c87:4f00:8544:fa0c:4267:b750]
I have reworded this to "of the nucleus (and also of the whole atom or ion)." Dirac66 ( talk) 22:16, 3 December 2020 (UTC)
