    Covalent-network (also called atomic) solid- Made up of atoms connected by covalent bonds, the intermolecular forces are covalent bonds as well. Characterized as being very hard with very high melting points and being poor conductors. Examples of this type of solid are diamond and graphite, and the fullerences.

    Saiharini Senthil 3 years, 10 months ago

    Schottky defect is a type of point defect or imperfection in solids which is caused by a vacant position that is generated in a crystal lattice due to the atoms or ions moving out from the interior to the surface of the crystal.

    Sia ? 3 years, 5 months ago

    Halides have the high tendency to oxidise other atoms that is why they lie towards the top of the table for standard electrode potentials of all elements. Due to electronic repulsion between the lone pairs in unhybridised s and p orbitals, group 16 elements show decreasing tendency to be in +2 state down the group rather they tend to show more stability towards +4 and +6 states. Thus selenium stays in lower oxidation state and do not form dihalides.
