what is a gas?
a substance or matter in a state in which it will expand freely to fill the whole of a container
the basic unit of a chemical element
an atom or molecule with a net electric charge due to the loss or gain of one or more electrons.
Atoms are always moving no matter what phase they are in: solid, liquid, gas.
True
False
What happens to molecules when the temperature drops or lowers?
The molecules get closer together
The molecules start moving faster.
The molecules stop moving.
The molecules become smaller.
The attraction between particles is greatest in
solid
liquid
gas
plasma
What is an ionic Bond
When metals join
when nonmetals join
Force of attraction holding positive ions and negative ions together
A bond made by sharing electrons
Ionic compounds are usually formed from _____.
two nonmetals.
a metal and a nonmetal.
two metals.
Which word means conducts electricity when dissolved
molecule
mixture
compound
electrolyte
The following properties are all characteristics of ionic compounds EXCEPT
high melting and boiling points
soft
crystal lattice structure
conduct electricity when dissolved in water
Solid
Which set of elements is most likely to form an ionic compound?
Na and O
C and O
Na and K
What happens to sodium when chlorine and sodium collide
sodium takes chlorine's electron
sodium loses an electron to chlorine
sodium and chlorine share electrons
sodium gains a proton
What type of forces hold on an ionic lattice together?
Electrostatic (magnetic) forces
Covalent bond
Metallic bond
Van der Waals forces
Why are ionic bonds strong and solid
every positive is attracted to every negative
every positive is attracted to every positive
their valence electrons
why are not always solid
Chemical A is charged, Chemical B is Charged, Chemical C is not charged and Chemical D is not charged. (all chemicals are in the liquid state). Which chemicals will dissolve in each other
All will dissolve
A and B will dissolve
C and D will dissolve
A and B will dissolve
C and D WONT dissolve
A and D will dissolve
C and B will dissolve
A and B WONT dissolve
C and D will dissolve
Why are ionic bonds brittle?
they are made of metals
every negative is attracted to every positive
they have high melting point
they are not, sometimes they are liquid
Oil and water don't mix because
water is less dense than oil
water is charged and oil is not charged
neither have a charge so they just sit there
Factors affecting the value of lattice energy
the size of the ions only
the charges of the ions only
BOTH the size of the ions AND the charges of the ions
Choose the ionic compound with the greater magnitude of lattice energy.
CaCl2
CaS
Choose the ionic compound with the greater magnitude of lattice energy.
NaCl
NaBr
