Midterms are in 5 days, I've got everything down except for this ionic and covalent bonding stuff! Please tell me the difference between them. I'm in 7th grade, so not too advance, please. Thanks!

In an ionic bond the electron actually leaves one atom, and goes to another. When an electron leaves an atom, the atom loses the 1 negative charge of the electron and becomes positive (positive ion). The atom that gets the jumping electron gains the 1 negative charge and becomes negative (negative ion). The 2 atoms are now held together by electrical forces. A covalent bond is where the electron is not given up as in ionic, rather the electron is now shared between atoms.

Covalent bonds form when two atoms share a pair of electrons, one from each atom.

An ionic bond is formed when an atom donates an electron to another. The donating atom is now positively charged, the accepting atom negatively charged. The two attract each other because of electrostatic forces.

Covalent Bonds share electrons. No ions, no giving and taking of electrons. 'C', 'H' and the diatomic atoms (H N O F Cl Br I) are always covalent. The rest are ionic.

Ionic Bond have one atoms that gives up electrons (has a positive charge) and one that takes electrons (has a negative charge). Opposites attract so . . .

Get an "A".

Ionic bond is a chemical bond between a metal and a nonmetal
and involves the complete transfer of valence electrons from the
metal to the nonmetal so as to produce two ions with different charges.The electrostatic force of attraction between these two oppositely charged ions brings about the ionic or electrovalent bond and is therefore a very powerful bond .An example of a compound in which such bond exists is sodium chloride which involves an interraction between sodium and chlorine in which sodium which has 1 valence electron transfers its valence eletron to chlorine which has 7 valence electrons thereby ensuring that both atoms attain the stable octet electronic configuration by having 8 electrons in their outermost shells(also known as valence electrons).Ionic compounds ganerally have very high melting points due to the strong electrostatic force of attraction that exists between the ions forming the bond .

Covalent bonding on the other hand is as a result of the mutual sharing of equally donated valence electrons between two atoms which are mostly nonmetals. In contrast to ionic bonding,atoms and not ions are involved in this chemical bond.Such bond exists inbetween atoms of the same element to form diatomic molecules of an element as well as in organic compounds eg methane.You should also note that the essence of this interraction is for the reacting atoms to gain stable configuration(octet or duplet)as in noble gases.Such compounds formed have very low melting or boiling points as the case may be.

oooooooooooooooof I am tired.
