Just about anything in the beginning of the table. Hydrogen is used to make bombs and there's a reason you can't smoke near oxygen. Magnesium will give a pretty amazing show when tossed in a fire and sodium reacts with water. It has to be kept under a layer of oil because any moisture can make it explode.
Sodium is a very reactive chemical element.
The temperature is higher and the soot is minimal.
Punctuated equilibrium
An element that has two outer electrons is carbon. Carbon would not use the energy to gain six more electrons when it can easily get rid of the two outer electrons.
This property can be useful in containing substances, like if you want to contain liquid nitrogen you would use an iron container (or practically any other element because nitrogen is almost inert) because the two elements don't interact with each other.
A Phoenix
Throw water on it. The logical answer.
The Phoenix can rise from its own ashes.
He bursts into flames and dies, then is reborn from the ashes.
Your car bursts into flames and tries to kill you with a spoon
I believe that you think to alkali metals (ex. sodium).
A Phoenix is a bird that bursts into flames when it gets old. Out of the ashes it is reborn as a Phoenix chicken.
it breaks either fizzles out and burns, bursts into flames or goes BANG!
Yes they can but the Grip paper might not have the sandpaper feel to it
Phosphurus
Oxygen and acetylene are used.
It is the temperature at which paper, in this case books, spontaneously combusts (bursts into flames). 451 degrees Fahrenheit.
