Ionic Bonds, Polar Covalent Bonds, Non-polar Covalent Bonds

what happens after the transfer of an electron?

an electrostatic force happens, it hold electrons together

what causes atoms to be more electronegative than others?

1. atomic number 2. distance of valence electrons from the nucleus

define anion

A negatively charged ion

define cation

A positively charged ion

If one element in a bond is more electronegative than the other element, what does this do to its charge?

charge becomes more negative

what happens to an atom's charge when it gains an electron?

charge becomes negative (accepting an electron)

what happens to an atom's charge when it loses an electron?

charge becomes positive (giving up an electron)

difference between ionic bond and covalent bond

covalent bond: electrons shared ionic bond: electrons transferred

match terms: ionic bonds/covalent bonds; between metals and nonmetals/ between two or more nonmetals

covalent bonds between two or more nonmetals; ionic bonds between metals and nonmetals

difference between non polar covalent bond and a polar covalent bond

non polar covalent bond: electrons shared equally polar covalent bond: electrons shared unequally

when you have two of the same atoms in a bond, what bond is it (C-C)?

non polar! (EN=0)

what is the bond btw metal-nonmetal

usually ionic

what can the electronegativity difference tell you?

can help you determine what bond something is if electronegativity is greater than or equal to .5 then the bond is polar if electronegativity is less than or equal to .4 then the bond is nonpolar
