cement | Definition, Composition, Manufacture, History

Cement, in general, adhesive substances of all kinds, but, in a narrower sense, the binding materials used in building and civil engineering construction. Cements of this kind are finely ground powders that, when mixed with water, set to a hard mass.Setting and hardening result from hydration, which is a chemical combination of the cement compounds with water that yields submicroscopic

Adhesives, cement, disinfectants, fertilizers, etc. The molecular orbital theory treats compounds not as having individual bonds between atoms, but as sharing electrons with multiple atoms through their orbitals. In this way, hydrogen atoms are "bonded" between 2 other atoms at a time, in that a pair of electrons is shared between 3 atoms at once.

DOC 1.2 Units of Measurement - Csun

Scientific notation is a method which simplifies the writing of very small and very large numbers and computations involving these. In scientific notation, numbers are expressed as the product of a number between 1 and 10 and a whole-number power (exponent) of 10. The exponent indicates how many times a number must be multiplied by itself.

Every subshell has a # of orbits s/p/d/f that can each hold 2 electrons each (one has the opposite spin of the other). The first shell (of all atoms) has 1 subshell of s-orbitals containing 1 s orbital. This means that the first shell can hold 2 electrons. The second shell has 2 subshells: 1 s-orbital and 3 p-orbitals.
