Metallic Bonding, properties |
- formed between atoms of metallic elements -electron cloud around atoms -good conductors of electricity at all states, lustrous, very high melting points -malleable |
|
|
metallic bond |
bound found in metals; holds metal atoms together very strongly.
|
|
|
ionic bond |
bond formed between two ions by the transfer of electrons |
|
|
ionic compound properties |
-form crystals -high melting points -hard and brittle -conduct electricity when aqueous and molten -metal and non metal (cation and anion) -soluble in water |
|
|
covalent bond |
bond formed by the sharing of electrons |
|
|
covalent compound properties |
-between nonmetallic elements of similar electronegativity -formed by sharing electron pairs -stable non-ionizing particles, they are not conductors at any state -low melting points -amorphous structure (no lattice structure) |
|
|
what results when metals react with non metals? |
ionic compounds |
|
|
why do metals lose electrons in ionic bonds? |
to match the number of valence electrons of their nearest noble gas |
|
|
what forms when the number of electrons are less than the number of protons in an ionic bond? |
positive ions |
|
|
Bonds in all the polyatomic ions and diatomic are all what type of bond? |
covalent |
|
|
non polar covalent bonds |
when electrons are shared equally, do not dissolve in water |
|
|
polar covalent bonds |
when electrons are shared unequally , do dissolve in water |
|
|
alloys- |
a solution of a metal in a metal |
