periodic table Flashcards
what are some trends you notice in the periodic table? #1
All families/ groups have elements similar to each other
what are some trends you notice in the periodic table #2
families/ groups react to different elements similarly
what are some trends you notice in the periodic table #3
atmoic mass gets bigger as you go down
what are some trends you notice in the periodic table #4
They go in numerical order (1-109)
what tells you the number of electron shells?
Period
What tells you how many electrons are in outer shell or “valance electrons”
Group
what is the number above the element symbol?
Atomic number
what is the element symbol?
An abbreviation for the element
what is the numbers at the bottom of the element
Atmoic Mass
How to determine amount of Protons
Atomic Number
How to determine amount of electrons
Atomic Number
How to determine number of Neutrons
Mass minus Protons
How to determine amount of Lewis Dots
Group (collum)
What way does the group go?
Up and down
What way does the period go?
Left and Right
How to determine amount of electrons if its three rings?
The 3rd ring is the group #, the 1st ring is always 2. then the third ring is what ever amount of electrons are left.
How to determine amount of electrons if its two rings?
The 1st ring will still always be two, then the 2nd ring will be whatever amount of electrons are left.
How to determine amount of electrons if theres only 1 ring?
Amount of protons
Alkali metals
Group 1, most reactive metals on the table.
Alkaline Earthmetal
Group 2, reactive but not as reactive as group 1
Transition Metals
Groups 3-12. ,metals with a lot of use
Metalloids
Group 13 to Group 16, 17, or 18. Elements with properties of both metals and non metals.
Halogens
Group 17, most reactive non-metals used to clean.
Noble Gasses
Group 18, never react with anything.
