Lecture 4: The atom Flashcards
atoms are made up of
subatomic particles
metals properties
-conduct heat and electricity
-malleable (hammer)
-ductile (wire)
-shiny solid at room temp (not Hg)
non metal properties
-poor conduction
-gases at room temp
metalloids properties
properties of metals and nonmetals
Group 1
Alkali Metals
Group 2
Alkaline Earth Metals
Group 16
Chalcogens
Group 17
Halogens
Group 18
Noble Gases
neutral atoms
protons # = electron #
coulumbs law of electrostatic interaction
opposites attract
charges and force of attraction are
directly proportional
distance and force of attraction are
inversely proportional
strength of interaction depends on (2)
-magnitude of charges
-distance between them
