Ice melts at 0 degrees C, Diamond remains solid until its temperature is above 3500 degrees

Look at the images of ice and diamond.  In some senses you might say the two substances are similar.  Both substances are solid,  transparent and crystalline. In terms of bonding, they have similarities too :   In ice, atoms of oxygen are held to hydrogen atoms by covalent bonds. In diamond atoms of carbon ar...

Covalent bonding can lead to the formation of lattices

Covalent bonds form when electrons are shared between nuclei Atoms which can form two or more covalent bonds can bond with other similar atoms or themselves and form covalent lattices. Carbon in the form of diamond is a good example,  as is silicon dioxide in the form of quartz. A valuable lattice   Activity. Diamond - clos...
