Part 1 Flashcards
this is the study of matter and its composition, properties, and transformations including the energy changes accompanying it
Chemistry
anything that has mass and occupies space
Matter
the two properties of matter
A. Intensive
B. Extensive
this is independent on the amount of material
Intensive Properties
this is dependent on the amount of material
Extensive Properties
what are the seven classifications of matter
- solid
- liquid
- gas
- ionized Plasma
- Bose-Einstein Condensate
- Fermionic Condensate
- Quark-Gluon Plasma
draw the classification of matter based on composition
yep draw
this have dispersed particles larger than solutes but smaller for the mixture to become heterogeneous
Colloids
it has evenly distributed particles but does not settle
Colloids
it can be distinguished by Tyndall effect
Colloids
this is the scattering of light by sufficiently large particles
Tyndall effect
make a table for the types of colloids with the ff. headers: dispersed phase, dispersed medium, name of colloid, example
pic
this is made up of nucleons
Nucleus
nucleons are made up of
protons and nuetrons
what is the proper nuclide notation
pic
in the nuclide notation, A,Z, and X stands for
A- mass number
Z- atomic number
X- element
basic formulas for the calculation of #protons, # neutrons, #electrons
pic
these are the atoms of same element but differ in number of neutrons
Isotopes
are atoms that have the same atomic number but different mass number
Isotopes
atoms that have the same mass number but different atomic number
isobars
atoms that have the same number of neutrons
Isotones
atoms that have the same number of electrons
Isoelectronic
it is the number of protons in the nucleus of an atom
Atomic number
is the total number of protons and neutrons in the nucleus of an atom
Mass number
is the weighted average of the atomic masses of the isotopes based on their percentage abundance
Average atomic mass
make a table with regard to the types of radioactive decay
pic
what are the magic numbers used for the prediction of the type of decay
2,8,20,28,50,82
these are considered the stable isotopes
magic numbers
in the prediction of type of decay, the bigger atoms means it is
electron capture
in the prediction of type of decay, the smaller atoms means it is
positron emission
what are the steps (you made this yourself) when predicting the type of decay?
- if Z>83
- get #p and #n
- n/p
- beta or positron/electron capture?
- is it big or small?
these radioactive decays are first order
Kinetics of Decay
this is the time wherein the original amount is reduced to half
Half-life
