Covalent Bonds Rev.
covalent bonds review for test
Question | Answer |
---|---|
where are the cations and anions(metals/nonmetals)on the periodic table | cations are on the left and anions are on the right |
what are the subatomic particles involved in chemical bonding | valence electrons |
why do elements undergo bonding in the first place | to complete a full octet like the noble gases |
what are the three types of chemical bonds | ionic,covalent,metallic |
ionic bond | electrons transferred :sodium chloride |
covalent bond | electrons shared:water |
metallic bond | electrons shared:copper |
determine if ionic | metal+nonmetal |
determine if covalent | nonmetals |
determine if polyatomic | both -an ion composed of more than one atom |
covalent compound properties | nonmetals and a nonmetals,weaker bonds,liquid/gas state,solids are soft solids,dissolve sometimes,doesn't conduct electricity,low melting points |
ionic compounds properties | metals and a nonmetal,stronger bonds,hard brittle salts,dissolves in water,conducts electricity,high melting points |
