3.1.3 Bonding Flashcards
ionic bonding?
electrostatic attraction btwn oppositely charged ions in a lattice
formula:
sulphate
hydroxide
nitrate
carbonate
ammonium
SO4)2-
OH-
NO3-
CO3)2-
NH4+
COVALENT BOND
shared pair of electrons
dative covalent bond
shared pair of e-s, both supplied by one atom
how are the following represented?
-covalent
-dative
-line
-arrow
metallic bonding?
attraction between delocalised e-s and positive ions in a lattice
practice shapes MUST DO NO MATTER WHAT THIS IS MUY IMPORTANT DO IIIIIIIIITTTTTTTTTT
fine, on you then 😡
define elctronegativity
ability of the nucleus of an atom to attract a pair of e-s to itself in a covalent bond
Q1: why could e- distribution be unsymmetrial?
Q2: type of bond produced?
Q3: elements could have a ….
elements of different electronegativities.
polar covalent
….permanent dipole
permanet dipole?
what is it, hat kinds of molecules is it btwn?
btwn polar molecules
Forces between two molecules that have permanent dipoles are called permanent dipole - dipole forces
induced dipole?
when a polar molecule temporarily distorts the electron cloud of a nonpolar molecule
hydrogen bonding?
strong attraction between a hydrogen atom bonded to electronegative atoms (like O, N, or F) and a lone pair of electrons on another electronegative atom
