Why do metals only form ionic compounds while metalloids and nonmetals form ionic and covalent compounds? Why can SiCl4 (silicon tetrachloride) react with water and produce SiO2 and hydrochloric acid while CCl4 (carbon tetrachloride) cannot? What is the difference in molecular chemistry be...
Is silicon hexachloride an ionic or a covalent compound? A bond formed between a silicon atom and an oxygen atom is likely to be: A. Ionic B. Coordinate covalent C. Polar covalent D. Nonpolar covalent Is XeF4 an ionic or covalent comp...
Although siderophores are highly selective for Fe3+, they can strongly bind many other metals, particularly those with a charge and ionic radius similar to that of Fe. Sc may also interact with the same Fe-binding ligands due to similar physicochemical properties. Evidence for Sc–Fe competit...
In electronics,solid staterefers to components and systems based entirely onsemiconductormaterials, such as silicon, germanium orgallium arsenide.Transistorsanddiodes-- the most common solid-state devices -- are often combined with resistors, capacitors and other components to create integrated circuits (...
Why is latent heat of fusion of solid carbon dioxide less than that of silicon dioxide ? View Solution Give reason for the following in one or two sentences : ''Solid carbon dioxide is known as dry ice.'' View Solution View Solution ...
The reaction of the two atoms eliminates any electron charge, because the atoms combine in the ratios needed to use all excess electrons. With a balanced number of electrons the valence is considered zero, and there is no plus or minus sign used in amolecular formula. Ionic molecules tend to...
There are four types of crystalline solids:ionic solids, molecular solids, network covalent solids and metallic solids. Is NaCl a crystalline solid? Acrystalline solidis a solid that has a regular, repeating three-dimensional structure. A crystal of NaCl (Figure 14.5. 1) is one example: at th...
t particularly efficient conductors because conduction in electrolyte solutions is achieved through ionic, rather than electronic conduction; instead of loose electrons moving between atoms serving as the charge carriers, ions (atoms or small groups thereof that have a charge due to a surplus or ...
Is this compound molecular or ionic?Covalent and Ionic Compounds:A chemical compound can either be ionic or covalent, depending on the type of chemical bond existing between the elements in the compound. There are certain rules followed while naming ionic and covalent compounds....
