name the different allotropes of silicon?
The molecular structure of graphene differ from the other allotropes of carbon diamond and graphite in that graphene consist of a single layer of atoms.
In that case, scientists talk about different "allotropes". For example, graphite and diamond are different varieties of carbon - the same atoms, in a different arrangement.
two allotropes of boron ; crystalline boron and brown amorphous boron

sulphur
minerals differ in appearance and texture
One is a hard gray substance. One is a brown powder
Yes ofcourse Hydrogen have two allotropes, Ortho hydrogen and para hydrogen. They differ only in having parallel and anti parallel nuclear spins. It was first observed by Heisenberg in 1927. BY RAJESH KUMAR GDC MPM SINDH PAKISTAN
1700s is when baseball started
phosphorus
Yes, P4 and P8 (also P12) are all allotropes.
Allotropes have the same atomic number, number of protons, number of electrons, etc. but the chemical and physical properties may differ strongly.
No, it does not have any allotropes.
for a phone? tablet? ipod? be more specific. it really depends on the type of device, type of case, type of leather and the type of silicone. leather is more for appearance than for protection. silicone is more for protection that for appearance. i think my ipod touch case if silicone and i have dropped that thing a bunch of times so hard that i thought for sure it was broken, but it has survived. if i had a leather case on it, my ipod would defiantly be broken. so i would recommend protection over looks.
