Palladium (Pd) or Samarium (Sm)
He created a periodic table arranged by atomic mass. He wasn't the first, but he was the first to leave spaces in his table for unknown elements. At his time, there were only 63 known elements. Based on the elements around the blank space, scientists could predict the properties of the unknown element. The spaces were filled in when they were discovered.
Actually in response to this answer, everything I have read clearly states that metals far out number all nonmetals, just look at the Periodic Table. that guy is so wrong you are right :) SO HELP FULLU JERK WE HATE U >:< Your answer is correct I have checked it this answer has been given a certified stamp by: Gabriel
The element with the most protons can change at any time so I can't give you a per fect answer but as I am aware of as of 2/19/2009 the unofficial element with the most electrons is ununoctium (Uuo) and the highest official is Roentgenium (Rg) at 111. P.S. there's this guy named Michael Dayah and he update this periodic table contsantly you should check it out if this gets out dated!!!!
He meant what he said. It was nice kissing you. As in, he liked it.
If a guy/girl like you they will be nice to you. But, if they are mean, they probaly just useing you.
All those listed on the Periodic Table.
some guy called Mendeleev
because they aren't straight or family guy
the each square on the periodic table of elements tells you about how much atoms something has. FOR EXAMPLE: when you and your boy/girl friend get in the mood you all take off your clothes and get into bed. Once you get in bed the guy sticks his PENIS in the womans VAGINA. If you forget birth control or condums or some other kind of protection you create a child when the sprim greets an egg. That is how things are chemically attracted to one another
some black guy who who smokes crach

I assume you know that Dmitri Mendeleyev was the man that discovered the periodic table and left spaces for future findings of elements. He also has an element names after him. He wrote a book. He is a great guy.
YES! extremely nice guy!
Nice Guy was created in 2012-08.
Yes KANE is really a nice guy. He looks like evil monster but he is very nice guy.
Ya i guess he's a nice guy.
a nice guy is nice to everyone and doesn't talk bad about anyone. a nice guy would open the door for her and tell her she looks pretty. but you can't just act like your nice you have to be nice and if you are she will notice.
