PERIODCY. Flashcards
RULES, FOR IONISATION ENERGY EQUATIONS.
THE STATE SYMBOL IS IN FACT GAS, (g.).
FIRST IONISATION ENERGIES, GROUP SEVEN,7.
FIRST IONISATIOON ENERGY DECREASES AS YOU GO DOWN GROUP SEVEN,7.
ALTHOUGH, THE NUMBER OF PROTONS IS INCREASING.
THIS IS BECAUSE, THE ELECTRON BEING REMOVED IS, ONE SHELL OF ELECTRONS, FURTHER AWAY FROM THE NUCLEUS.
WITH ONE SHELL OF ELECTRONS, GIVING MORE SHEILDING, FROM THE NUCLEUS.
WHY DOES CHLORINE HAVE A GREATER FIRST IONISATION, IN COMPARISSION TO SULFUR?
THIS IS BECAUSE, SULFUR, S, HAS ONE,1, LESS PROTON THAN CHLORINE.
AND THE ELECTRON BEING REMOVED IS FROM THE SAME SUBSHELL.
PERIODICITY.
A TREND, OR PATTERN OF REPEARTING PHYSICAL PROPERTIES AND CHEMICAL PROPERTIES, WITH AN INCREASING ATOMIC NUMBER.
ATOMIC RADII DECREASE FROM LEFT TO RIGHT.
WHAT CAUSES METALLIC BONDING TO GET STRONGER?
AS THE NUMBER OF DELOCALISED ELECTRONS INCREASES.
AS THE RADIUS OF THE CATION DECRASES.
AS THE CHARGE ON THE CATION.
CHANGE IN A GRAPH, AS YOU CHANGE THE SUBSHELL THAT THE ELECTRON IS LOST FROM.
THE FIRST IONISATION ENERGY DECREASES.
