qualitative
description
quantitative
Numbers
formula of density
mass /volume
density
amount of matter in a given space
compactness
characteristic physical property
The properties of a thing and quantities use to describe it
precision
Measure of how close values are to each other
accuracy
Measure of how close values are to the meeting or no value
can measurements be precise and not accurate
yes because they can be close to each other there and to the value
what does limewater and cobalt chlorine test for
Carbon dioxide and water
electromagnetic spectrum
radio, micro, infrared, visible, uv, X-rays, gama, cosmic
what is the order of visible light
red orange yellow green blue indigo violet
what color has the longest wavelength
red
what color has the highest energy
violet
destructive interference
waves cancel out and creates nodes
photon
carries energy
Albert einsteins
quanta
bundle of energy
max Planck
how is light produced in an atom
atom is excited, absorbs energy , falls back, photon is released
florescence
UV light is converted to visible light, whining and bulbs is converted to UV lights, white clothing is treated, money and driver license has stamps
phosphorescence
electrons take several seconds to cascade down,
frequency
occurrences of a repeating event per unit timeline
c
speed of light m/sec
h
wavelength m,nm,angstrom
V
frequency 1/sec
E
energy cal
h- real h
plancks constant cal/sec
s
cylinder
p
peanut
d
daisy
what is the difference between the 1s and 2s orbital
the 2s is larger
how many electrons can any orbital configuration hold
2
how many enelctons can the s p d f
2,6,10,14
anion
when an atom gains electrons
cation
when an atom looses electrons
will bromine gain or lose electrons
gain 1
periods
a row
family of elements
column
when moving across from left to right what happens to the radius
smaller
do you move down the table what happens to the radius
larger
most reactive metal
Francium
most reaction nonmetal
fluorine
why are periods arranged together
same valence electrons
reactivity as you go down the left side
more reactive
reactivity as you go down the right side
less
valence election of an atom says
highest principal level
Metal
malleable, conducts electricity, luster, ductile, electron doner, makes up majority
nonmetal
brittle, electron acceptor, insulator
how are periods arranged
how many electrons are present
ionization energy
energy needed to knock a valence electron off
solubility
polar desolves polar
no polar desolves nonpllar
surface tension
reduces surface area
wetting agent
increases adhesion
cohesion
joining same together
adhesion
joining different
hard water
water with calcium and magnesium
how does hard water affect soap
scum
how does soap work
bridge between soap and water
anion
negative
cation
