Why diamond is very hard and graphite is soft?
Diamond is harder than graphite because each of its carbon atoms form four covalent bonds in a tetrahedral structure and also due to the presence of strong covalent bonds in it. Therefore, diamond is hard but graphite is soft and slippery even though both have carbon present in them.
Is Diamond a soft material?
Graphite is soft because it has weak inter molecular forces between its layers. Diamond is hard due to its giant covalent lattice and it has many strong covalent bonds.
Is Diamond strong or weak?

Does diamond armor work in real life?
In short, armor made from Diamond would likely shatter at first contact with a weapon, and would not be suited to use as a traditional armor of any kind.
Will touching lava kill you?
Lava won’t kill you if it briefly touches you. You would get a nasty burn, but unless you fell in and couldn’t get out, you wouldn’t die. With prolonged contact, the amount of lava “coverage” and the length of time it was in contact with your skin would be important factors in how severe your injuries would be!
Can I drink lava?
If you tried to eat it, you would suffer burns before you ever got it in your mouth. If it was poured into your open mouth by someone else, it would cause third degree burns. You wouldn’t be able to swallow it — lava is molten rock, and as such, is extraordinarily dense and viscous.
