Bonding 5 (ionic Compounds) Flashcards
Ionic compounds are arranged in a
Crystal lattice
A crystal lattice is a three dimensional structure that is created when a _ forms
Salt compound
Nonmetal anions are larger in size than
Metal cations
The cations fit in the spaces between the _ as they line up
Anions
A crystal lattice looks like a
Marshmallow toothpick cube
Ionic bonds form due to large differences in _ among the ions
Electronegativity
Electronegativity is not the same as
Electron affinity
Electron affinity is the energy charge when an electron is accepted by
A neutral atom
Electronegativity is the ability of an atom to _ in a chemical bond
Attract itself to the electrons
The difference in electronegativity is easy to see when two elements from _ bond
Opposite sides of the periodic chart
Electronegativity increases across a period form _ to _
Left
Right
Ionic bonds will form neutral even if
More than one of same element is required
Because magnesium is in group 2, it gives up _ electrons
2
Because Cl only accepts one electron, in order to bond with magnesium
You need two chlorine and one magnesium
Two chlorine and one magnesium bond looks like
MgCl2
