IONIC BONDING Flashcards
WHAT ARE IONS
CHARGED PARTICLES THAT CAN BE SINGLE ATOMS OR GROUPS OF ATOMS
WHAT ARE NEGATIVE IONS CALLED (…)
ANIONS
WHEN ARE ANIONS FORMED
WHEN ATOMS GAIN ELECTRONS- THREY HAVE MORE ELECTRONS THAN PROTONS
WHAT ARE POSITIVE CHARGED IONS CALLED
CATIONS
HOW ARE CATIONS FORMED
FROM WHEN THEY LOOSE ELECTRONS- THEY HAVE MORE PROTONS THAN ELECTRONS
THE NUMBER OF ELECTRONS LOST OR GAINED IS THE SAME AS (…)
THE CHARGE ON THE ION
EXAMPLE: IF 2 ELECTRONS ARE LOST (2+)
GROUP (…) ELEMENTS ARE METALS; THEY (…) ELECTRONS TO FORM A POSITIVE CHARGE
1,2 AND 3/LOSE
GROUP (…) ELEMENTS ARE NON-METALS; THEY (…) ELECTRONS TO FORM A NEGATIVE CHARGE
5,6 AND 7/GAIN
ELEMENTS IN THE SAME GROUPS ALL HAVE THE SAME NUMBER OF ELECTRONS IN THEIR OUTTER SHELL; SO THEY CAN LOSE OR GAIN THE SAME NUMBER OF OUTER ELECTRONS; THIS MEANS THEY FORM (…)
IONS WITH THE SAME CHARGE
TRANSFER OF ELECTRONS PRODUCES AN (…)
IONIC COMPOUND
WHEN ARE IONIC COMPOUNDS FORMED
WHEN A METAL AND A NON-METAL REACT TOGETHER, SUCH AS WHEN GROUP 1 METALS REACT WITH GROUP 7 NON-METALS
THE METAL ATOM LOSES ELECTRONS TO FORM A POSITIVE ION (CATION) AND THE NON-METAL GAINS THESE ELECTRONS TO FORM A NEGATIVE ION (ANION)
WHAT HAPPENS WITH OPPOISITELY CHARGED IONS IN IONIC COMPOUND
THIS OPPOSITELY CHARGED IONS ARE STRONGLY ATTRACTED TO ONE ANOTHER BY ELECTROSTATIC ATTRACTION (THIS ATTRACTION IS CALLED IONIC BONDING)
WHAT IS IONIC BONDING
WHEN THE OPPOSITELY CHARGED IONS ARE STRONGLY ATTRACTED TO ONE ANOTHER BY ELECTROSTATIC ATTRACTIONS
EXAMPLE OF AN IONIC BONDING
THE REACTION BETWEEN SODIUYM AND CHLORINE
-THE SODIUYM ATOM GIVES ONE OUTTER ELECTRON AND BECOMES Na+ ION
-THE CHLORINE ATOM RECIEVES ONE ELECTRON AND BECOMES CI- ION
