In giant molecules such as diamond, silon dioxide, the atoms are all regularly positioned and form a lattice. In this respect they are similar to ionic compounds.
Giant covalent, lattice structures contain a lot of non-metal atoms, each joined to adjacent atoms by covalent bonds. The atoms are usually arranged into giant regular lattices. The structure requires an element with very strong bonds between the atoms to create various materials. A couple of examples are (carbon) Diamond and Buckminster Fullerine. Graphite is also one but has weak bonds as well. Silica and molybdenum can also make covalent lattice structures.
Gallium arsenide (GaAs) is classified as a compound semiconductor with covalent bonding. It forms a covalent bond between the gallium atom and the arsenic atom in its crystal lattice structure.
A crystalline solid held together by covalent bonds
No, water is not a giant covalent structure. Water molecules are held together by hydrogen bonds, which are much weaker than the covalent bonds typically found in giant covalent structures like diamond or graphite.
The types of chemical combinations are as follows: 1. Electrovalent (or ionic) combination 2. Covalent combination, which is classified into (a) Ordinary covalent combination, (b) Coordinate covalent combination

They can form a network covalent bonding as in boron nitride.

The valence electrons are the only electrons involved in chemical bonding. In covalent bonding sharing occurs In ionic bonding electrons are tranferrred In metallic bonding they are deloclaised across the lattice

Indeed they can. A common example of Carbon covalently bonding with carbon is in what we refer to as Giant Covalent Structures, which are multiple of an atom bonded together in a set, lattice-like shape. Examples of giant covalent structures made from carbon are diamond where the atoms are arranged in a pyramid shape, and graphite, where they are arranged in flat layers.
covalent bonds
These are giant molecular lattice structures. This implies that strong covalent bonding holds their atoms together in a highly regular extended network. The bonding between the atoms goes on and on in three dimensions. Melting requires the separation of the species comprising the soild state, and boiling the separation of the species comprising the liquid state. Because of the large amount of energy needed to break huge numbers of covalent bonds, all giant covalent network structures have high melting points and boiling points and are insoluble in water. Diamond, graphite (allotropes of carbon) and quartz (silicon(IV) oxide, SiO2) are examples.
