btw this is for my hw...just really confused about them and have a test tomorrow and dont have textbook with me bc im not at my house
but thanks anyway

i know the naming rules...just have trouble distinguishing which is which if u explain each one and how u know it its which from the formula ill get it
2007-02-05 12:16:31 · update #2
what do u mean transfer of electrons compared to sharing electrons?

1. an ionic bond is "the stealing of electrons", one atom steals electrons to complete its outer ring.
2. Don't Know
3. a covalent bond is "the sharing of electrons", two atoms share electrons to complete their outer rings.
4. Don't Know

Ionic - electrical attraction between oppositely charged ions.
Polyatomic - a group of nonmetallic atoms covalently bonded which carry an overall positive or negative charge for the group.
Covalent - electrons are not given away or accepted, they are shared between two atoms.
Molecular - must occur between two nonmetallic atoms which will form molecules instead of networks or crystals.
Naming? Ionic are simply named for the ions present. The metallic ion is named first and the nonmetallic ion second. The name ends in "ide".
NaCl = sodium chloride
CaCl2 = calcium chloride
AlCl3 = aluminum chloride
Polyatomic are named for the metallic ion, then the polyatomic ion.
NaNO3 = sodium nitrate
Na2SO4 = sodium sulfate
Na3PO4 = sodium phosphate
Molecular are named for the nonmetals present and end in "ide". They use prefixes to tell the number of atoms of each element present in the molecule.
CO = carbon monoxide
CO2 = carbon dioxide
P4O10 = tetraphosphorus decoxide

i know that an ionic bond is when two ions (atoms that either gain or lose valance electrons) come together to make a new substance and it happens with a metal and a nonmetal. A covalent bond is between two nonmetals and they share electrons. sorry but i don't know what polyatomic and molecular bonds are so i can't help you out on those but these are what i know. i hope this somewhat answers your question.

1. Ionic, cation and anion, sodium chloride, Na+ Cl-
2. Polyatomic, each atom bound up with every other atom in a network, boron carbide, (BN)x
3. Covalent, shared electrons, hydrogen chloride, H-Cl(gas)
4. Molecular, same as covalent.

ionic bonds are between atoms or ions that are ionic because it has gained or lost an electrons... covalent form two ormore atoms when sharing an electron.. hydrogen are share oxygen and hydrogen atoms.. and molecular are just when they are bonded... when you have them add up properly... i hope i maybe helped a little

ionic is a bond btwn metal atom ( group 1 or 2 in periodic table ) with nonmetal atm.e.g: MgCl2. ( usually grup 14 n upward in periodic table ). while covalent is a bond btwn nonmetal atm with nonmetal aom. e.g:CCl4.
