Chemical bonds Attractive forces that compounds

Chemical bonds Attractive forces that hold atoms together in elements and compounds. 

Why are carbon dioxide and sodium chloride so different Why can we divide compounds into two categories that display distinct physical properties The answers come from an understanding of chemical bonds the forces that attract atoms to each other in compounds. Bonding involves the interaction between the valence electrons of atoms. Usually the formation of a bond between two atoms creates a compound that is more stable than either of the two atoms on their own. 

Chemical bond The attractive force that holds atoms together in a compound. 

CHEMICAL BOND IS THE ATTRACTIONAL FORCE THAT HOLDS ATOMS TOGETHER IN COMPOUNDS. 

Chemical bond An attractive force that holds atoms in molecules or compounds. 

The transfer of an electron creates ions — cations (positive charge) and anions (negative charge) — and opposite charges attract each other. The Na cation attracts the Cl anion and forms the compound NaCl, or table salt. This is an example of an ionic bond, which is a chemical bond (a strong attractive force that keeps two chemical elements together) that comes from the electrostatic attraction (attraction of opposite charges) between cations and anions. 

Atoms combine with one another to give compounds having properties different from the atoms they contain The attractive force between atoms m a compound is a chemical bond One type of chemical bond called an ionic bond, is the force of attraction between oppositely charged species (ions) (Figure 1 4) Ions that are positively charged are referred to as cations, those that are negatively charged are anions... 

Comparing the two relative forces of electrostatic attraction that you calculated, you can conclude that ionic bonding is considerably stronger in magnesium oxide. This affects the physical properties and chemical behavior of the two compounds. For example, the melting point of MgO (2,852° C) is much higher than that of LiF (845° C). 

Analogical molecular structure is possessed by other simple compounds such as potassium iodide, ammonium chloride, sodium hydroxide, barium nitrate, ammonium acetate and so on. In all these compounds there is a transfer of one or several electrons from one element to the other, positive and negative ions being thus formed, that are hold together in a crystal by electrostatic attraction. A bond of this kind is no genuine chemical bond in tbe correct meaning of the term, but is just,a result of Coulomb forces of attraction between opposite charges.
