18 BONDING

Chemical PROPERTIES depend on the number
of valence electrons.
18 BONDING

Therefore, chemical bonding and
reactivity depend on an element’s
electron configuration.

STABLE ELECTRON CONFIGURATION:

Which group does this describe?

When an atom gains or loses electrons, what
does it get?
 A CHARGE.

IONIC BONDING – the forming of a stable
electron configuration through electron
transfer between a metal and a nonmetal

ION: An atom with a positive or negative
CHARGE from electron transfer.


IONIC BONDING – the forming of a stable
electron configuration through electron
transfer between a metal and a nonmetal
In the bond, one becomes positive (loses
electrons) and one becomes negative (gains
electrons).


Positive Ion (loses electrons): Cation
Negative Ion (gains electrons): Anion

HOW can you predict which elements will
make positive cations and which will make
negative anions?
