Ionic compounds are held together by ionic bonds. Intermetallic compounds are held together by metallic bonds. Complexes are often held together by coordinate covalent bonds. Note that some compounds contain a mixture of ionic and covalent bonds. Also note, a few scientists do not consider pure el...
Ionic compounds tend to have higher boiling points than covalent compounds. both ammonia NH 3 and methane CH 4 are covalent compounds but yet the boiling point of ammonia 130C is higher than methane Which of the following covalent bonds is the most polar (i.e. h...
The type of bonds holding elements together in a compound can vary: two common types arecovalent bondsandionic bonds. The elements in any compound are always present in fixed ratios. Example 1:Pure water is a compound made from two elements - hydrogen and oxygen. The ratio of hydrogen to ...
Ionic compound, any of a large group of chemical compounds consisting of oppositely charged ions, wherein electron transfer, or ionic bonding, holds the atoms together. Ionic compounds usually form when a metal reacts with a nonmetal, where the metallic
Common salt (sodium chloride) is one of the best-known ionic compounds. Molecular compounds contain discrete molecules, which are held together by sharing electrons (covalent bonding). Examples are water, which contains H2O molecules; methane, which contains CH4 molecules; and hydrogen fluoride, ...
Molecular compounds are held together by covalent bonds and ionic compounds are composed of ionic bonds. Molecular substances, or molecules, are composed of two or more nonmetals that share electrons. This lesson will explore molecular compounds, including their properties, covalent bonding, and ...
Molecules can themselves form ions and react with other ions to create ionic bonds. Such compounds behave as ionic compounds as far as the ionic bonds are concerned, but they also have covalent bonds. For example, nitrogen can form covalent bonds with four hydrogen atoms to produce the ammonium...
Chemical bonding Covalent bonding; mostly with carbon-hydrogen (C-H) bonds Mostly ionic bonding; mostly lacking C-H bonds Origin Essentially, biological (as a result of biological activity) Chemical (from laboratory works or experiments) or geological (as a result of a natural process unrelated ...
