Igcseboy:
6CH01 jan 2009 question 24 c) i and ii

like how to get to the answer !!!!!

Darth Austrakast:
i)For this you have to know the trend in first ionisation energy across the period---

ii)The trend increases because along the period, number if protons in the nucleus increases and hence effective nuclear charge increases.So the electrons are more strongly attracted to the nucleus. Also number if shells along a period remains same...hence shielding effect or screening effect by outer shell electrons remains same

Hope this helps

Here I attach a worksheet regarding this topic you might find useful ;)
