Silicon dioxide, or silica, is an example of a covalent lattice. Silicon is tetravalent, meaning it will form four covalent bonds; in silica each of these bonds is to an oxygen. The silicon-oxygen bond is very strong and this makes silica a very stable structure with a high melting point...
In object-oriented programming, polymorphism (from the Greek meaning "having multiple forms") is thecharacteristic of being able to assign a different meaning or usage to something in different contexts- specifically, to allow an entity such as a variable, a function, or an object to have more...

presence of nickel, iron, and related substances. Diamond is soluble in these metals, meaning that it reacts with them chemically and dissolves. This makes it useless as a tool for cutting iron or steel. CBN, on the other hand, does not react and can therefore be used to cut these ...
This fundamental difference influences their chemical behavior and the types of compounds they form. 6 In terms of chemical reactivity, metallic character is associated with a low electronegativity and a low ionization energy, meaning metals can easily donate electrons in chemical reactions. Non-...
