THE PERIODIC TABLE Flashcards
WHY IS THERE A PERIODIC TABLE
IT IS LAID OPUT SO THAT ELEMENTS WITH SIMILAR PROPERTIES FORM COLOUMNS
WHAT ARE THE VERTICAL COLOUMNS CALLED
GROUPS
THE GROUP TO WHICH AN ELEMENT BELONGS CORRESPONDS TO (…)
THE NUMBER OF ELECTRONS IT HAS IN ITS OUTTER SHELL
WHAT ARE GROUP 1 ELEMENTS CALLED
ALKALI METALS
WHAT ARE GROUP 7 ELEMENTS CALLED
HALOGENS
WHAT ARE GROUP 0 ELEMENTS CALLED
NOBLE GASES
WHAT ARE THE RAWS CALLED
PERIODS
THE PROPERTIES OF THE ELEMENTS DEPEND ON…
THE NUMBER OF ELECTRONS THEY HAVE
THE ATOMIC NULMBER IS EQUAL
TO THE NUMBER OF ELECTRONS EACH ATOM HAS
THE PERIODIC TABLE CAN BE SPLIT INTO TWO PARTS…
METALS AND NON-METALS
METALS AND NON-METALS ARE SEPARATED…
IN A ZIGZAG FROM BORON TO ASTATINE
NON-METALS ARE ON THE…
RIGHT-HAND SIDE
METALS ARE ON THE…
LEFT-HAND SIDE OF THE PERIODIC TABLE
CHARACTERISTICS OF METALS
1) METALS COONDUCT ELECTRICITY BECAUSE THEY ALLOW CHARGE TO PASS THROOUGH THEM EASILY
2) METAL OXIDES ARE BASIC; THIS MEANS THY WILL NEUTRALISE ACIDS
3°) METAL OXIDES WHICH DISSOLVE WILL FORM SOLUTIONS WITH A PH OF MORE THAN 7
CHARACTERISTICS OF NON-METALS
1) NON-METALS ARE POOR CONDUCTORS OF ELECTRICITY
2) NON-METALS OXIDES ARE ACIDIC; THIS MEANS THAT THEY WILL NEUTRALISE BASES
3) THEY DISSOLVE IN WATER TO FORM SOLUTIONS WITH PH OF LESS THAN 7
