ND STANDARDS
ent Standards
STM-S-3
nts will construct and/or interpret diagrams that illustrate ionic and covalent bonding.
TM-S-4
nts will predict compound formation and bon type as either ionic or covalent.
TM-S-10
nts will relate the chemical behavior of an element, including bonding, to its location on the periodic table.
ANDINGS
Overarching Understanding
H-STM-U-6
dents will understand that elements are able to form an almost limitless variety of chemical compounds by th
ing or exchange of their electrons. The rate at which these combinations occur is influenced by a number of
ables. The compounds produced may vary tremendously in their physical and chemical properties.
ET-U-8. Students will understand that while the total amount of energy in the universe is constant, th
t that is available for useful transformations is always decreasing. Systems within the universe will c
tion once the energy differential becomes zero.
ET-U-8
s will understand that heat is a manifestation of the random motion and vibrations of atoms or molecules with
ce. Interactions between or among atoms or molecules naturally move toward states of higher disorder.
ET-U-10
s will understand that all Earth systems/processes require either an internal or external source of energy to fun
s to any component, or to the quantity or type of energy input, may influence all components of the system.
ET-U-12
s will understand that technological problems often create a demand for new scientific knowledge, and new
ogies make it possible for scientists to conduct their research more effectively or to conduct new lines of resea
ailability of new technology often sparks scientific advances.
ET-U-13
s will understand that technology affects society because it solves practical problems and serves human needs
e affects society by stimulating thought or satisfying curiosity, or by influencing views of the world, or by prov
dge necessary for new technological advances
L QUESTIONS
Overarching
w can all the variety of matter in the universe be
ated by the combination of only 92 elements
n matter that looks different be composed of
milar substances?
Topical
What role do electrons play in bond formation?
DGE AND SKILLS
Related Misconceptions
nts think atoms actually become a single entity in
ng. Ex: Two smaller atoms join and form one
single atom.
nts think if you cannot see an atom it is not there
nts do not understand that you cannot create nor
oy matter.
wledge
nts will know…
onic bonds are formed and broken.
covalent bonds are formed and broken.
What are the basic types of chemical bonds?
a valence electron is.
here is a relationship between the number of valence electrons and the atoms location on the perio
metals form ionic bonds and nonmetals form covalent bonds
oning
nts will be able to....
guish between elements, atoms, and molecules.
t the type of bond formed based on the location of the element on the periodic table.
ls
nts will be able to…
ate models that illustrate types of bonding
e compounds in a laboratory setting.
hether an element is a metal or nonmetal based on its location on the periodic table.
he Octet rule to evaluate a simple covalent molecule.
o use electron configuration to determine whether an atom will tend to lose or gain electrons.
