Portage Learning
Chemical Bonding and Molecular Geometry
Question:
Ionic bond
Answer:
An ionic bond is electrostatic attraction between oppositely charged cations
in anions (metals and nonmetals)
Question:
How does a binary ionic compound form?
Answer:
A metal loses electrons (forming a cation) and donates them to a nonmetal
which gains electrons informs in anion, the compound is held together by the
force of electrostatic attraction
,Question:
Covalent bond
Answer:
Attractive force between the nuclei of a molecule's atoms and pairs of
electrons between atoms; a mutual attraction of atoms for a shared pair of
electrons
Question:
Between which types of elements do covalent bonds form?
Answer:
A covalent bond usually forms between two nonmetals
Question:
Isoelectric
Answer:
Term used to describe tow elements having the same electronic configuration;
the only difference is the number of protons
,Question:
Describe the trends of electronegativity
Answer:
Decreases going down the table, increases from left to right
Question:
Pure covalent bond
Answer:
A bond in which electrons are shared equally between atoms
Question:
Polar covalent bond
Answer:
A bond in which electrons are not equally shared between atoms
Question:
Pure covalent electronegativity difference
Answer:
less than 0.4
, Question:
Polar covalent electronegativity difference
Answer:
0.4 - 1.8
Question:
Ionic electronegativity difference
Answer:
greater than 1.8
Question:
Two nonmetals are generally ______. If they are directly beside each other on
the table, they are probably ______. If they are far away from each other, they
are probably ______.
Answer:
covalent; pure covalent; polar covalent
Question:
Metals and nonmetals are generally...
