New Shower Costs. The actual cost of a new shower depends on your location, the materials used, the complexity of the installation, and other factors. 1  A basic shower enclosure may cost as little as $400 to $600, while a combination bath/shower unit or a top-of-the-line surround could cost $1,500 to $3,000 or more.
A metal with a large number of free flowing electrons most likely has good conductivity
Metal. Valency: Since there are 4 electrons in the valence shell, they can make use of these electrons in the bond formation to get octet configuration. Hence their usual valency is 4. However the group 14 elements other than carbon can also show the maximum valency 6 due to the presence of available d-orbitals in them. But carbons maximum valence is 4 due to non availability of d-orbitals. Oxidation number: Their usual stable oxidation number is +4.
