L1 - Electronegativity and Bond Type
Terms in this set (13)
high electronegativity means
an atom is very good at grabbing electrons (usually nonmetals)
the electrons are shared equally
the electrons are shared but not equally.
Atoms with an EN difference of more than 2.0. The electrons are transferred NOT shared.
Ionic compound properties
High melting and boiling points. nonconductors unless melted or aqueous (they are electrolytes) brittle and exist in a crystal lattice
involves sharing of valence electrons
Covalent compound properties
low Melting and Boiling points, nonconductors soft when solid
a molecule that has two poles, or regions, with opposite charges
partial positive charge
the less electronegative atom
Low electronegativity means
an atom is not very good at grabbing electrons (usually metals)
partial negative charge
more electronegative atom
dipole arrow points towards
the more electronegative atom (where the electrons spend more time)
two or more atoms held together by covalent bonds
