the periodic table Flashcards
to be good at science
How do you determine the reactivity of an element?
The number of electrons in the outermost shell
whats michael jackson’s fave element
He He
What is the reactivity of elements on the periodic table?
the reactivity of metals decreases as you go from left to right and it increases as you go down on the periodic table.
How do metals on the periodic table react?
Metals react by losing electrons. They have a low ionization energy so it’s fairly easy for them to lose electrons.
How do you know if one element is more reactive than another?
In a reactivity series, the most reactive element is placed at the top and the least reactive element at the bottom.
What is the only letter that isn’t in the periodic table?
The letter J
What type of elements usually have alkaline oxides?
Similarly to Group 1 oxides, most group 2 oxides and hydroxides are only slightly soluble in water and form basic, or alkaline solutions. Beryllium is unreactive with air and water.
what do these symbols stand for?
“S”
Sulfur
Sc
Scandium
Ag
silver
Al
Aluminum
Why were there gaps in the periodic table?
They are elements that haven’t been discovered yet
what is the periodic table song?
There's Hydrogen and Helium Then Lithium, Beryllium Boron, Carbon everywhere Nitrogen all through the air
With Oxygen so you can breathe
And Fluorine for your pretty teeth
Neon to light up the signs
Sodium for salty times
MAGNESIUM, Aluminum, Silicon, PHOSPHORUS Then Sulfur, Chlorine, and Argon POTASSIUM and Calcium so you'll grow strong SCANDIUM, Titanium, Vanadium and Chromium and MANGANESE
This is the Periodic Table Noble Gas is stable Halogens and Alkali react aggressively Each period we'll see new outer shells While electrons are Added moving to the right
Iron is the 26 then Cobalt
Nickel coins you get
Copper, Zinc, and Gallium
Germanium and Arsenic
Selenium and Bromine film
While Krypton helps light up your room
Rubidium and Strontium
Then Yttrium, Zirconium
NIOBIUM, Molybdenum, Technetium
RUTHENIUM, Rhodium, Palladium
SILVER-WARE then Cadmium and Indium
TIN-CANS, Antimony then Tellurium and Iodine and Xenon and then Caesium and Barium is 56, and this Is where the table splits Where lanthanides have just begun Lanthanum, Cerium and Praseodymium
Neodymium's next to Promethium then 62 Samarium, Europium Gadolinium, and Terbium Dysprosium, Holmium, Erbium Thulium, Ytterbium, Lutetium
HAFNIUM, Tantalum, Tungsten Then we're on to RHENIUM, Osmium, and Iridium PLATINUM, Gold to make You rich 'till you grow old MERCURY to tell you When it's really cold
THALLIUM and Lead then Bismuth for your tummy POLONIUM, Astatine would not be yummy RADON, Francium will last a little time RADIUM then Actinides at 89
This is the Periodic Table Noble Gas is stable Halogens and Alkali react aggressively Each period we'll see new outer shells While electrons are to the right
Actinium, Thorium, Protactinium Uranium, Neptunium, Plutonium Americium, Curium Berkelium, Californium Einsteinium, Fermium, Mendelevium, Nobelium Lawrencium, Rutherfordium Dubnium, Seaborgium Bohrium, Hassium then Meinerium, Darmstadtium Roentgenium, Copernicium
Ununtrium Flerovium Ununpentium Livermorium Ununseptium Ununoctium And then we're done
