1st Quarter Flashcards
Molecules that make up all things
Matter
______ Are atom
Element
The basic unit of chemical element
Atom
2 or more elements being bonded together to form a new compound or molecule
Compound
HCL
Hydrochloric Acid
Hydrogen Chloride
visual perception of different wavelengths of light reflected by a substance
Color (Intensive)
the feel or appearance of a surface
Texture (In)
degree or intensity of heat present in a substance lobject
(in) Temperature
quantity of matter within a given Object
(ex) Mass
the amount of space that a substance / object occupies.
(ex) Volume
mass of a substance per unit volume
(ex) Density
the way a substance reflects light.
reflection
(in) Luster
the ability of a substance to be stretched without breaking
stretched into a wire
(in) Ductility
the ability of a substance to deform or be molded into different shape
(in) Malleability
solid, liquid, gas
the physical form in which substance exist
(In/ex) State / State of matter
the temperature at which a stolid turns into liquid/vice versa
(in) Melting pointm/ freezing point
the temperature at which liquid turns into gas / vice versa
(in) Boiling point / Condensation point
a measure of how resistant a material is from scratching or abrasion
Hardness
color of mineral is its powdered form (scratch)
color when rubbed in a porcelain plate
Streak
color of mineral is its powdered form (scratch)
Streak
the external form, contours or outline of someone or something
Shape
Lowest density element
Hydrogen
0.0009 g/cm³
Highest density element
Osmium
23 g/cm³
4th state of matter
Plasma
-does not depend on the amount Something of substance present
Determine by the chemical composition of the particles and their structure ( arrangement ) ( intensive - internal )
Intensive Property
One does depends on the amount of substance present
Depend only on the amount of particles, not on their composition or internal arrangements ( external - extensive)
Extensive Property
Structure of diamond
Covalent bond, carbon atom
Structure of graphite
Covalent bond, weak binding forces, carbon atom
Nonmetal to nonmetal, sharing of electrons
Covalent Bond
taking of electrons
Ionic
sharing of electrons
covalent
Only quality that is observed through chemical reactions
Chemical Property
A trait of matter that can only be observed if a substance has the property
In the process of testing the chemical Property, the substance change composition it it has that property
Chemical Property
-rusting ( iron)
tarnishing ( silver, copper, brass, etc.)
Reactivity with oxygen
Chemical Property
tendency of a substance to chemicaly react w/ water
Reactivity with water
Chemical Property
tendency of a substance to chemically reacts with acid
Reactivity with acids or bases
Chemical property
tendency of matter to burn
Combustibility/Flammability
- tendency of matter to burn
Combustibility/Flammability
What something is made of is always a Chemical property
Chemical Formula ( chemical composition)
Chemical formula of
Rust
Water
Diamond
Rust - Fe2O3
Water - H20
Diamond - C
All chemicals properties are intensive, none are extensive
Why?
Because chemical properties never depend on how much a substance is present, but only on what kind of particles make up the substance
A distinctive property that helps you determine the identity of a material
Characteric property
Mohs Scale of Hardness
10 - Diamond
6.5 - Ceramic
5.5 - Glass
3.5 - Penny
2.5 - Fingernail

Saturated hydrocarbon is
Alkanes
The group of organic compound that is consist of one or single bond
Saturated hydrocarbon
The group of organic compound that is consist of on one double bond/ one triple bond
Unsaturated hydrocarbon
Saturated hydrocarbon - single bond
Alkanes
Unsaturated hydrocarbon - double bond
Alkenes
Unsaturated hydrocarbon
Triple Bond
Alkynes
one or more species of atoms of a chemical element w/ the same atomic number and position in the periodic table and nearly identical chemical behavior but with dif. atomic mass and physical property
Isotopes
electrons in the outermost shell and highest energy level of an atom
Valence Electron
used to describe the arrangement and distribution of electrons based on its increasing level of energy and orbital/sublevel
Electronic configuration
the device used to write the electronic configuration of given elements
