This is the force that holds atoms together.
Cation
Chemical Bond
Isotope
Dihybrid cross
Atoms with low or high numbers of valence electrons are often what?
Molecules
Unstable
Metals
Nobel Gasses
This type of bond is formed when two atoms share valence electrons.
Ionic
Covalent
Isometric
Tectonic
This type of bonding occurs primarily between nonmetals.
Ionic
Covalent
Tectonic
Plutonic
Identify properties of covalent bonds from the following list:
low melting points
poor conductors of energy
usually gasses at room temperature
low melting points
What is the only chemical element from this list that forms a DIATOMIC stable molecule at room temperature:
Hydrogen
Iodine
Neon
Xenon
True or False: Double bonded molecules are less reactive than single bonded molecules.
True
False
In this type of bonding, there is a complete transfer of valence electrons between atoms.
Covalent
Ionic
Isotonic
Compounding
Ionic bonds require two things:
an electron donor
a polar molecule
an electron acceptor
a halogen
This is the smallest part of a compound that has the properties of that compound:
Atom
Molecule
Ion
Isotope
This is a molecule that has a partial positive end and a partial negative end because of unequal sharing of electrons:
ionic molecule
covalent molecule
polar molecule
compound
This is a characteristic of a nonpolar molecule:
dissolve in water
both atoms pull evenly on each other
explosive gas
I've got nothing on this one
Why are chemical compounds like recipes?
if you change the ingredients, you get a different product
No one can remember them without a cookbook
They require heat to form
They require strict measuring
This is the best statement of what the Octet Rule is:
Electrons are attracted to one another
8 electrons are always found in the outermost shell
losing or gaining electrons so that the outer shell now has 8 valence electrons
Four plus four usually equals 8 electrons
Ionic compounds usually have high (a) .
