in covalent compounds, the two ions being bonded share electrons. these are called covanlence electrons. in an ionic bond, they share the electrons in a different way.

Ionic compounds usually have high melting points, as there are strong electric forces holding the ions in the crystal lattice. Covalent compounds are fat-soluble, ionic ones are either insoluble or water soluble. Compounds of elements from opposite ends of the periodic table are ionic, for instance group 1 metals and halogens. Nitrogen and oxygen are next to each other so nitrogen oxides are covalent.

Salt (Na Cl) is an ionic compound and dissolves easily in water (H2O), a covalent compound. The covalent bonds are much stronger than the ionic bonds.

I believe covalently do not physically share electrons but are rather just closely attracted to each other. And ionic is a stronger bond where electrons are actually physically shared. Ionic is a harder bond to break then covalent is.

Ionic bonds are a type of chemical bond based on electrostatic forces between two oppositely-charged ions. In ionic bond formation, a metal donates an electron, due to a low electronegativity to form a positive ion or cation. In ordinary table salt, the bonds between the sodium and chlorine ions are ionic bonds. Often ionic bonds form between metals and non-metals. The non-metal atom has an electron configuration just short of a noble gas structure. They are electronegative, and so readily gain electrons to form negative ions or anions. The two or more ions are then attracted to each other by electrostatic forces. Such bonds are stronger than hydrogen bonds, but similar in strength to covalent bonds.
Covalent bonding is an intramolecular form of chemical bonding characterized by the sharing of one or more pairs of electrons between two components, producing a mutual attraction that holds the resultant molecule together. Atoms tend to share electrons in such a way that their outer electron shells are filled. Such bonds are always stronger than the intermolecular hydrogen bond and similar in strength to or stronger than the ionic bond.

An ionic bond is a bond where electrons are transfered from one ion to another, a covalent bond is where they are shared

Ionic compounds contain at least one metal, molecules don't.
Molecules are bonded by electrons holding them together. Ionic compounds are attracted to eachother because one ion is + and one is -.
Ionic compounds form crystals, molecules do not.
Ionic compounds have high melting points, molecular compounds have low melting points.

Ionically-bonded compounds can separate into ... well ... ions when dissolved, usually in water. A super example of an ionically-bonded compound is sodium chloride, table salt. In water, the sodium ions and choride ions separate and float around separately. You know that when a sodium atom and a chlorine atom combine to form a molecule of sodium chloride, the sodium atom gives up one electron and the chlorine atom picks it up.
Co-valent compounds don't have electrons given up and acquired. The atoms of co-valent compounds share their elections, so the atoms of the compound cannot separate and float around.

ionic bonds
- strong bonds
- have high melting points
- excellent conductors
-Bonds between metals and
nonmetals
Covalent bonds
-weak bonds
-low melting points
-poor conductors but excellent insulators
Bonds between nonmetals
-share electrons
*Both use valence electrons to bond
