1. Elements are the primary types of matter. What make one element different from another?
a
The number of protons, electrons, and neutrons is different.
b
The number of neutrons is different.
c
The number of protons and neutrons is different.
d
The number of protons is different.
2.What is an element's atomic number ?
a
The number of protons and neutrons in one atom of the element.
b
The number of protons in an atom of the element.
c
The mass of one atom.
d
The order in which it was discovered.
3. What is the name for multiple atoms that are bonded together?
4.
What is the difference between an atom and an ion?
a
An ion is an atom that does not have an equal number of electrons and protons, so it can have a
negative or positive charge.
b
An ion has a higher atomic number than the corresponding atom, and must share its proton with
a neutron.
c
An ion is an atom that turns into a anion or cation when it shares an electron with another
element.
d
An ion is a charged atom that doesn't have the proper balance of neutrons and protons.
5.
Match the chemical bond to it's definition:
Question 5 options:
a
metallic
b
covalent
ionic
When atoms share electrons so that their outer electron shells are filled.
When atoms lose an electron to another atom, balancing the charge of the two atoms.
When electrons can flow from atom to atom.
When the charge of an atom or a molecule is distorted by a neighboring atom or molecule,
setting up a weak attraction between them.
6.
When matter changes phase from a solid to a liquid, it is called:
Question 6 options:
a
melting
b
freezing
c
condensation
d
sublimation
7. What needs to happen for a substance to change state from a gas to a liquid...or the opposite?
a
Pressure, temperature, or both can change.
b
Both pressure and temperature need to change.
c
Only pressure needs to change.
d
Only temperature needs to change.
8. What happens to liquid water at room temperature if the atmospheric pressure is reduced
sufficiently?
a
It bubbles, releasing gases dissolved in the water.
b
It freezes at room temperature.
c
It boils/vaporizes at room temperature.
d
Nothing- boiling and freezing require temperature changes.
a The number of protons, electrons, and neutrons is different.
b The number of neutrons is different.
c The number of protons and neutrons is different.
d The number of protons is different..
