PYRAMIDAL
SIGMA
SINGLE
TETRAHEDRAL
TRIGONAL
TRIPLE
Find the words listed below AND write a brief description of what the word means or how it is
used in chemical bonding.
BOND: when electrons are transferred or shared between elements
to for a new substance
COORDINATE: a type of bond where the Lewis dot structure is
drawn as if both electrons used in bonding were donated by the
same element(atom)
COVALENT: a type of bond (between two non-metals) where the
electrons are shared
DOUBLE: a covalent bond where 2 pairs (4 electrons) are shared;
this is a type of “pi” bond that is rigid and doesn’t “spin”
IONIC: a type of bond where electrons are transferred to form
cations and anions
METALLIC: the type of bonding that occurs in metals described as
a bunch of cations surrounded by a “sea of electrons”; helps
explain why metals are malleable.
PAIR: two electrons that form a bond or just take up space and
push the other electrons away (VSEPR theory or shapes)
PLANAR: a flat molecular shape that results from 3 bonds and no
lone electron pairs (the shape Boron likes to make)
PYRAMIDAL: a polar molecular shape like Nitrogen likes to make
SIGMA: another name for a single covalent bond that helps us
remember that it allows the molecular shape to “spin”
SINGLE: when two electrons are involved in a covalent bond
TETRAHEDRAL: the 3-dimensional shape formed when an atoms bonds
4 times (like carbon)
TRIGONAL: when there are three bonds coming from a central atom
(usually part of trigonal planner)
TRIPLE: a type of covalent bond where 6 electrons (three pair)
are involved in bonding, this is another type of “pi” (or rigid)
