in a period , elements are not arranged in the sequence of

a)decreasing charge in the nucleus

b)increasing ionisation energy

c)increasing charge in the nucleus

d)increasing size

i think the answer is a,d.

tell me whether i am correct or not?

reply is must.

is the answer a and d?

 the answer should be a and d. 

as atomic no increases nuclear charge also increase so periodic table can't be arranged in terms of decreasing nucleus charge

in lanthanoids and actinoids there is lantanoid and actinoid contraction respectively therefore there is decrease in size in the elements of those periods.

WELL I THINK ANS IS A,B,D

for option A it is obvious , as the atomic number increases along the period,so the charge increases

for option B here there are some exceptions in the table so its not always increasing

( for ex if we take example of sulphur & phosphorous)

for option D as we goes rightward the size decreases due to INCREASE  in nuclear charge

PLZ RATE

BEST OF LUCK

WELL ITS OBVIOUS I THINK!!!!!!!!!!1

the correct options are   a) nd d).....
