Diamond has stronger bonding because of the fact that it has 2p valence orbit whereas Silicon has 3p valence orbit. Moreover we know that as we go farther away from Nucleus the shielding of electrons takes place.Due to this shielding, the bonding becomes weaker. In case of Silicon carbide and Silicon dioxide 3p orbits are participating in bonding. Hence the shielding leads to weakening of bond.Shielding is not there in case of Diamond as mentioned. Hence this is the reason why Diamond is harder.
What else can I help you with?
Can diamond scratch quartz?
There are double-terminated quartz crystals that have remarkable clarity and smooth crystal faces, which have non-scientifically been referred to as diamond quartz--the Herkimer Diamond is one so-named type of quartz crystal.
Will quartz cut glass like diamonds?
No. Diamonds cut glass because diamonds are harder than glass. Quartz is not as hard as diamond.
Why is quartz harder than steel?
Why is quartz harder steel
Which rocks are harder than a nail?
Rocks that are harder than a nail, which typically has a hardness of around 5 on the Mohs scale, include quartz, topaz, and diamond. Quartz, with a hardness of 7, is commonly found in various types of rocks. Topaz ranks at 8, while diamond is the hardest known natural material, scoring a 10 on the Mohs scale. Other hard rocks include corundum and garnet, which also exceed the hardness of a nail.
Will quartz scratch a peice of copper?
Yes, quartz is harder than copper on the Mohs scale, so quartz can scratch copper.
What things are harder than emeralds?
Yes an emerald or green beryl is harder than quartz
On mohs' hardness scale what mineral is harder than quartz but harder than appetite?
If you mean isn't harder than quartz but harder than apatite ( you spelled it wrong), that would be Orthoclase Feldspar. Else the minerals that are harder than both apatite and quartz are topaz, corundum, and diamond (diamond being the hardest, well the hardest non synthetic mineral).
Can diamond scratch quartz?
There are double-terminated quartz crystals that have remarkable clarity and smooth crystal faces, which have non-scientifically been referred to as diamond quartz--the Herkimer Diamond is one so-named type of quartz crystal.
Which is harder diamons or quarts?
Diamond is harder than quartz. Diamond scores a 10 on the Mohs scale of mineral hardness, while quartz typically ranges from a 7 to 7.5. This means diamond is more scratch-resistant and durable compared to quartz.
Why is quartz harder than steel?
Why is quartz harder steel
Will quartz cut glass like diamonds?
No. Diamonds cut glass because diamonds are harder than glass. Quartz is not as hard as diamond.
Are quartz and diamonds very soft minerals?
No. Quartz is harder than steel (based on the Mohs scale of mineral hardness), and diamond is THE hardest mineral.
Is emerald harder than diamond?
No. Diamond is harder than emerald.
What is harder diamond or onyx?
Diamond is harder than onyx.
Which is harder diamond or plastic?
Diamond is harder than plastic.
Are harder than calcite but sofyer than quartz?
kaolin
What other stone which looks and shines like diamond but harder than diamond?
nothings harder than a diamond
