5. Minerals I                                                                                    (p. 72-78)

States of Matter

All matter exists in one of three states:

                   solid                             liquid                            gas


The controlling factors that dictate the state are: ____________ and ____________.

Example: at sea level, the following materials are in what state?

        gold - ___________________
        mercury - ________________
        oxygen - _________________



Temperature measurement:

Temperature scale used in geology: ________________________

        Freezing point of water: ____________
        Boiling point of water: ____________



                           To convert from °F to °C: Subtract 32 then divide by 1.8.
                            To convert from °C to °F: Multiply by 1.8 then add 32.


Pressure measurement:

Pressure scales used in geology include:

                    __________________(atm)          and       ________________ (Pa).
                                                                         5                   2
                   sea level pressure = 1 atm = 1.013 bars = 1.013 x 10 Pa = 14.7 lbs/in


The Stuff that Makes up all Matter

The make-up of solid matter on Earth, from smallest to largest is:

___________  ___________  ___________  ___________  ___________

Elements

Can we break down elements chemically?             YES or NO




                                                      1

Atoms

The atom is the smallest particle that uniquely defines an element, like a fingerprint.

        Typical approximate size of an atom: _____________

Particles that make up an atom:

   ______________ (charge is __________)

   ______________ (charge is __________)

   ______________ (charge is __________)


Protons and neutrons together define the ____________ of an atom.

The layers of electrons that orbit around the nucleus are called ______________ or
___________________________.

What is the definition of:

Atomic number: _______________________________________________________
                    (uniquely identifies an element)

Mass number: _______________________________________________________

Is mass number exactly the same as atomic weight?                  YES or NO

Can atoms of the same element have different atomic numbers?         YES or NO

        For example, each and every H atom has exactly ____ proton (atomic # = 1).

Can atoms of the same element have different mass numbers?           YES or NO

Atoms of the same element that have different mass numbers are called _________________

        Example: carbon can exist in 3 forms: _______________________________

The average weight of an atom of any element, taking into account the relative abundances of the
different isotopes of that element, is called the _________________.

Ions

Ions are what we get when the electrons partnered with one atom start fooling around with someone
else's atom.

Types of ions:

A LOSS of electrons creates a ____________ charged particle called a ___________ e.g. __________

A GAIN of electrons creates a ____________ charged particle called an ___________ e.g. __________
