Largest First IE help!!!Watch
The third quantum shell has higher energy level than second quantum shell
Edit: nvm this is wrong
No sorry I thought it was D but turns out its C. It was my mistake sorry I don't know why I said the answer was D lol instead of C
I think the reason should go like Ne having all of its quantum shell filled is much more stable than unfilled quantum shell of Mg
The answer is C, the best way to tackle these sort of questions is write out what each atom is, find it’s place on the periodic table and look for the trend. Ionisation energy tends to relate to atomic radii, the smaller the radii the higher the IE, you can look into something called effective nuclear charge which talks about shielding and something called penetration. But back to the question, the answer is C because as you know as you go along the period, the nuclear radii drops which means a higher overall IE, of course you have some exceptions to this such as aluminium and sulphur, but don’t worry about these kinda questions too much, I’m assuming it’s a 1 marker? (Haven’t done a level chemistry in over 5 years).
Yeah thought it would be, they had these sneaky questions when I sat my exams. Don’t worry about it too much, spend your time on the questions that have higher marks. Also if you have anymore questions feel free to ask.
