Is it possible for an atom to have a pure electrical charge?

AI Thread Summary
The discussion centers on the concept of atomic purity and its relation to friction. It is clarified that while individual atoms cannot be impure, samples of elements will never be 100% pure due to the presence of impurities. Friction is explained as primarily dependent on surface roughness rather than atomic purity. A question is raised about creating a frictionless surface, with a reference to electromagnetic interactions between atoms. Theoretical considerations suggest that for frictionless conditions, atoms would need to share the same electrical charge, but this remains a theoretical concept rather than a practical reality. The validity of another forum's explanation regarding friction and atomic charge is questioned, leading to a consensus that the explanation provided is not accurate.

Please don't hate if this is a stupid question, I am a freshmen in high school so I don't know this stuff.

What I am really talking about is how all atoms have some impurity in them which is why friction happens, but is there a way to create one with no impurity?

An atom is an atom, it can't be impure. If you have a sample of an element, then yes, it will never be 100% pure.

Friction has nothing to do with purity. It depends (mostly) on surface roughness.

If what you are talking about is a sample (a chunk if it is a solid), then no, it is basically impossible to have it completely pure. It is a mixture to start with, and it's not possible to separate it completely.

Sorry for the confusion. I recently found a forum taking about a object being friction less. In the forum they say that what really causes friction is a electromagnetic interaction between the atoms of both objects. They also said for it to be frictionless the atom would have to have the same electrical charge. He says it theoretical but not in reality. My question was theoretically how would you make a atom's charge completely positive.

That answer from suolintu is nonsense.

Oh okay thanks
 
It seems like a simple enough question: what is the solubility of epsom salt in water at 20°C? A graph or table showing how it varies with temperature would be a bonus. But upon searching the internet I have been unable to determine this with confidence. Wikipedia gives the value of 113g/100ml. But other sources disagree and I can't find a definitive source for the information. I even asked chatgpt but it couldn't be sure either. I thought, naively, that this would be easy to look up without...
I was introduced to the Octet Rule recently and make me wonder, why does 8 valence electrons or a full p orbital always make an element inert? What is so special with a full p orbital? Like take Calcium for an example, its outer orbital is filled but its only the s orbital thats filled so its still reactive not so much as the Alkaline metals but still pretty reactive. Can someone explain it to me? Thanks!!
