3.1.3 bonding (IP) Flashcards
what is he definition for bonding
the transfer of sharing of electrons between atoms
what is it called that describes how easily an element or functional group can attract electrons
electronegativity
what determines the bond type between two atoms/ functional groups
the difference in electronegativity
what is the difference in electronegativity for covalent bonds
X < 0.4
what is the difference in electronegativity for polar covalent bonds
o.4 < X < 1.8
what is the difference in electronegativity for ionic bonding
X > 1.8
when drawing ionic bonding what type of brackets are used?
[ ]
when drawing ionic bonding are all energy levels shown
no, only the outer shell
which way of writing charge is correct, 2+ or +2
2+
when drawing ionic bonding where does the element symbol go?
in the center
when drawing ionic bonding how do you show multiple of the same ion?
a big number before the brackets e.g. 2[ ]
electronegativity increases or decreases across an period?
increases
electronegativity increases or decreases down a group?
decreases
in ionic binding do metals loose or gain electrons?
loose
