question		réponse
enthalpy commencer à apprendre		energy required to break the bond
Intermolecular forces commencer à apprendre		- permanent dipole-dipole interaction - induced dipole - dipole forces - London forces
Dipole-dipole forces commencer à apprendre		- different or same molecules. - permanent
Hydrogen bonds commencer à apprendre		very strong, NOT Van der Waals, 2 conditions (the electonegative element must have at least one lone pair, hydrogen atom must be attached to a highly electronegative atom)
London forces commencer à apprendre		- weak and only for a second - 17 and 18 group mostly
covalent bond commencer à apprendre		electrostatic force of attraction between the shared pairs and the positively charged nuclei
ligands commencer à apprendre		te atomy z boku
lattice enthalpy commencer à apprendre		energy required to break one mole of a solid compound into ions in the gas phase
Ions commencer à apprendre		not volatile (nie lotne), in solid state they don't conduct electricity, in liquid yes, soluble mostly
