Books – including my own – indicate that some elements, such as carbon, copper and gold, have been known ‘since antiquity’ (antiquity is the ancient past, especially the period of classical and other human civilisations before the Middle Ages).
More interesting is the question of what we mean by an ‘element’ in the modern sense.
This understanding emerged slowly in fits and starts towards the end of the 18th Century. So even though we knew these substances, and even though the word ‘element’ was used, it was only then that we began to understand what we meant by the word in the modern sense.

Atom Theory

-Warning this will blow your mind!!!
A Oxygen atom has 8 electrons. So what if each electron represents each planet in the Milky Way: Mercury, Venus, Earth, Mars, jupiter, Saturn, Uranus, Neptune.
Think an Atom’s electron spins around it, kinda like earth. What about the sun how does that effect this theory… Its the nucleus of the atom. What if that ball of flame was just protons and neutrons. What if other galaxies are just different types of atoms a bunch of planets or electrons circling a nucleus. Scientist can’t go out there, it would be impossible to do. It would take years upon years to travel and they would run out of supplies. So obviously there would be more galaxies and their likely to have 1 to a million planets or something. Anyway our milky way galaxy could be an atom to something bigger! And what if it was just an endless loop of atoms. Like maybe our atoms are like little solar systems with other “things” on them. To conclude I believe that we could just be a small atom to something big…

Sir will there be any atom with out electron
Yes it is possible to have a single proton without an electron. This happens when in an Ionic Bond when (since we have one proton it’s Hydrogen) Hydrogen loses an electron to lets say Beryllium, after that Hydrogen is left with no electrons and a +1 charge, and beryllium now has 5 from the transfer leaving it with a -1 charge
I don’t know where I can ask the qustion,? that’s why I m asking here, #if 0= nothing then from were we are coming???
plz send me the mail–

What will be the name of the following carbon chain
Ch3-ch2-ch2-ch=ch-ch2
Hi. A friend of mine who thinks that she is under influence of black magic, meet a astrologer. the astrologer asked her to wear a t-shirt for 3 nights and then bring that to him. The astrologer cut some lemons and rubbed throughout the t-shirt. Then he used some water on her hands and face and asked her to keep the t_ shirt on her palm. Anyway, after about 15 minutes the shirt catch fire and the astrologer drop rest of water to put the fire down. I’m now wondering what chemical can cause this fire. I also been told that water was looks muddy. Would you please help me to find out what material potentially used by astrologer. Also I’m suspicious about acid in the lemons and water which has been used, as well as body fat or sweat perhaps was on the t_shirt too. She was telling me that at the first smoke color was white but it turns to black after T_shirt catch fire. The smell of fire was so bad like a rotten meat. Would you please help me to find out the truth. Thanks
