Minerals
- Naturally occurring
- Inorganic
- Solid
- Definite chemical composition
- Regular internal crystalline structure
Most rock forming minerals are silicates
Rocks formed from cooling lava and/or magma
Boe’s Reactio “eries sho hat teperature rocks formed
Atoms in a mineral are specifically ordered
A solid with disordered atoms are called a glass
Crystalline structure based on atomic patterns
Atomic arrangement is predictable and repetitive
Rare minerals display flat external faces
Crystal faces form best in the open
Crystals are often prized mineral specimens
Lattice Atoms are held in place by atomic bonds
Bond characteristics govern mineral properties
Covalent- molecules are held together through sharing electrons
Ionic- give up electrons, both filled outer shells
Metallic- nuclei and inner shells float in a sea of free electrons, electrons stream through metal
if there is an electric current
Van der Whaals and Hydrogen help hold molecules together
Polymorphs- same composition but different crystal structure, diamond and graphite are carbon
polymorphs
Physical properties-
Color- diagnostic for few minerals, varieties reflect trace impurities
Hardness- scratching resistance of mineral, compared to Mohs scale
Luster- the way a mineral scatters light, metallic or nonmetallic
Streak- the color of mineral crushed on a ceramic plate
Specific Gravity- related to desity, heft, ho heay it feels, ieral eight oer eight of

Crystal form- minerals vary in crystal face development, indicates growth history, anhedral
common, euhedral less so, (Anhedral- no crystal faces, grown in tight space, Euhedral- good
crystal faces, grown in open cavity, Subhedral- between the 2)

OneClass has been such a huge help in my studies at UofT especially since I am a transfer student. OneClass is the study buddy I never had before and definitely gives me the extra push to get from a B to an A!

Balancing social life With academics can be difficult, that is why I'm so glad that OneClass is out there where I can find the top notes for all of my classes. Now I can be the all-star student I want to be.

As a college student living on a college budget, I love how easy it is to earn gift cards just by submitting my notes.
