This section explores why elements bond to form compounds?
How do elements bond to form compounds? Why?
Explain the Hydrogen peroxide and Manganese dioxide reaction?
We also want to be finding interesting experiments in chemistry. Why are they important and how do they tie in with what we are covering? To help get the ball rolling we can look back at some great discoveries and experiments throughout history in the Science Channel's presentation of 100 Greatest Discoveries: Chemistry.
This weeks contract has you select a unique element from the periodic table and describe the compounds it is a constituent of.

I still can't find what "role" gold plays in its compounds. So does anyone know what gold's role is?
Is it possible for an element to have more than one type of bond?
things become compounds because we MIX THEM TOGETHER!!!!!!!!!!!!!!!!!!!!
:D
the hardest part to understand is the
equation. does anyone have clues on knowing whats the easiest ways to do equatins or at least UNDERSTAND IT?
how do you know whether an element will decompose another. I dont undestand how youknow that it will be a catalyst
How can some elements bond together more than others?
how can hydroden perocside bubble
Is it possible to combine a certain amount of hydrogen peroxide and mangnese dioxide together to make oxygen and drinkable water? And how can you tell that mangnese dioxide is a catalyst?
What is the difference between oxide dioxide and trioxide?
Could the same element bond to another of its type?
2H202=02+2h20 was the equation for the experiment. The maganese dioxide is a catalyst which means it basically decomposes the hydrogen and oxygen, and it shows up in the equation over the yield symbol, which obviously I cannot show. The hydrogen peroxide broke down to form oxygen and hydrogen.
A compound of Krypton called krypton diflouride reacts very well with water
How many compounds can an element have?
Why do some compounds react differently when they form than others? And why do some of these compounds only last for a little while when some are permanant?
What determines the structure of an element? Why don't all elements have the same structure?
Different compounds of the same elements are called alloys and are not considered compounds.
pania,
the basic concept of an equation is that everything on one side will show up on the other side in a different order. the letters indicate the element, and the little number after the letters indicate how many times the element appears in the compound. the big number before the letters indicates how many times a compound appears in the reaction.
taylor,
I looked it up and found that it has an electron on its valence shell so it forms compounds with halogens. thats all I found
Zach,
no they're not. they're called allotropes.
Jessica,
lets say an element can bond with itself six times. if you picture this, it looks like a cube. if it can only bond twice, you would probably get a string or even a circle, but there would be no way for it to turn up with the structure of a cube.
and alloys ARE compounds, Zach
