A naturally occurring, inorganic solid with a definite chemical composition.
used in film developing
used in electrical wiring
used in drywall aka wall board
used in fertilizer
rock salt also table salt
used in pencils
reacts with acid (HCl)
makes up limestone, which "saves PA from acid rain"
smallest part on an element with all of the characteristics of the element
smallest part of a compound with all of the characteristics of the compound
combination of two or more elements in a specific ratio
positive charged atomic particle found in the nucleus
neutral atomic particle found in the nucleus
negatively charged atomic particle orbiting the nucleus (1836 times smaller than a proton)
different types of atoms of the same chemical element, each having a different number of neutrons
An atom or a group of atoms that has acquired a net electric charge by gaining or losing one or more electrons.
characterized by two non-metals sharing of pairs of electrons between atoms.
type of bond that involves a metals and a nonmetal. The metal donates one or more electrons
the bonding of metals to metals
"Father of Modern Chemistry"
Model of atom
How many pounds of minerals does a person use each year?
The most common mineral family in the Earth's crust
The most common element in the Earth's surface
The second most common element in the Earth's surface
The Atomic Number
also tell how many e- and p+ are in the atom
protons + neutrons= mass number
use this formula to calculate # of n in atom
" Don't mess with the protons!"
the shine or lack of shine of a mineral (either metallic or non-metallic)
the way atoms align themselves to make flat planes
color of mineral's powder
the way a mineral breaks along a flat surface
resistance to being scratched
developed a scale 1-10 using commonly known minerals
glows with UV light
glows in dark
calcite exhibits this (seeing double)
causes a Geiger counter to react
usually leave a dark streak and have densities of 5g/cm3 or greater
usually have a light or no-color streak and have densities less than 5g/cm3
Density = mass divided by volume (D=m/v)
What is the equation for Density?
