act turns first on the question of whether the claimant is an employee of the person or entity against whom the claim is brought there are a number of different statutory definitions for the nouns employer and employee in the act but no definition for the verb employ
Silicates are minerals that contain silicon atoms bonded to oxygen atoms. The basic building block for all silicate minerals is called a tetrahedron, where one silicon atom is bonded to 4 oxygen atoms (Figure 3.6).Silicate minerals also often contain other elements, such as calcium, iron, and magnesium.ilicates are minerals that contain silicon atoms bonded to oxygen atoms.

A nonmetallic chemical element in the carbon family of elements. Silicon-atomic symbol Si - is the second most abundant element in the earth's crust, surpassed only by oxygen.Silicon does not occur uncombined in nature. Sand and almost all rocks contain silicon combined with oxygen, forming silica.When silicon combines with other elements, such as iron, aluminum or potassium, a silicate is formed. Compounds of silicon also occur in the atmosphere, natural waters, many plants and in the bodies of some animals.and and almost all rocks contain silicon combined with oxygen, forming silica.
