There are number of compounds made up of covalent bonds. for example water, protiens, silica and etc.
Silica is like Carbon, Basically its atoms form strong covalent bonds between each other(4 as they each have 4 electrons in their outer shell) these bonds are branched in a never ending pattern, many of these strong bonds have to be broken in order for Silica to melt and hence it has a high melting point
BaBr2 has two ionic bonds, but no covalent bonds.
2 covalent bonds
There are four bonds.All are covalent bonds.
There are four covalent bonds in one molecule of silica. It is made of two oxygen atoms that are chemically bonded to a single silicon atom.

Ionic compunds which are crystalline- have ionic bonds. Giant covalent can also be crystalline e.g. diamond and silica- these have covalent bonds. Molecular compounds crystallise - these have covalent bonds and the crystals are held together by van der waals forces. and sometimes by hydrogen bonds.
BaBr2 has two ionic bonds, but no covalent bonds.
2 covalent bonds
There are four bonds.All are covalent bonds.
It has four covalent bonds.They are polar bonds
maximum of five single covalent bonds as in PCl5
Three covalent bonds.
Silica has two double bonds.The compound is also called silicon dioxide (SiO2); each oxygen is attached to the silicon by a double bond (pi bond).This gives silica an overall linear shape. O=Si=O
A single covalent bond
