Chemical Bonding Overview

Conductivity – the ability of a material to conduct ______ or electricity

Thermal Expansion – when heat is passed through a material, its ______ changes

Malleability – the ability of a material to deform under pressure without ______

Transparency – the degree to which light can pass through a ______

Strength – determine if a material can bear a certain force without ______ or bending

Elasticity – describes the amount of deformation and return to its original shape that a material can ______

Electrical Insulators – many ceramics are excellent electrical insulators due to the absence of free electrons for electrical ______

Ionic Bonding – perhaps the easiest to describe and visualize. It is always found in compounds that are composed of both metallic and ______ elements.

Covalent Bonding – stable electron configurations are assumed by the sharing of electrons between adjacent ______.

Metallic Bonding – the final primary bonding, is found in metals and their ______.

Physical Property is a characteristic of a substance that can be observed or measured without changing the identity of the ______.

Thermal properties are those properties of a material which is related to its ______ of heat.

______ Resistance – shows how resistant a material is to chemical processes that cause corrosion or breakdown.

______ – it is the property of material which resist the flow of electric current through material. It is a parameter which indicates that how easily electric current flow through the material.

______ – it is the property of material which allow the flow of electric current through material.

______ Strength – it is the property of material which indicates the ability of material to withstand at high voltages. Generally, it is specified for insulating material to represent their operating voltage.

______ Coefficient of Resistance – indicates the change in resistance of material with change in temperature.

______ – if the junction, formed by joining two metals, is heated, a small voltage in the range of millivolt is produced. This effect can be used to generate electricity, to measure the temperature and to measure the change in temperature of objects.
