ionisation energy

Question 1

the first energy definition

Answer 1

the enrgy required to remove mole of electron from one mole of gaseous atoms

Question 2

what is the equation for ionisation

Answer 2

(g—->+ (g)+E-

Question 3

sulfur and phosphorous

Answer 3

sulfur and phosphorous are in the same sub level. sulfur has a pair of electrons. it has mutual repulsion which has less energy to remove sulfur.

Question 4

aluminium and magnesium

Answer 4

al - h.e.e is in the p sub level
mg- h.e.e is in the s sub level
p is higher than s. therefore it is less energy to remove
