This video was amazing. You really went to basics and built up which is what some online tutors don't tend to do. This is amazing for me as an Access to HE student who last did chemistry more than 4 years ago, even then with an awful (mostly absent) teacher and an even worse mindset and mentality to teach myself! Thank you so much for your time and effort into your channel!
I am really glad. And your a great teacher too. Understood everything. You made my chemistry more interesting for sure man. Thumps up on that keep up the good work.
Hi James, I've got a big question here, you've made this video on Period 3, does this trend or pattern occur with all the other periods in the Periodic Table?
Just two quick questions, answering them will be greatly appreciated: How is that there's metallic bonding with the Mg2+ ions and the sea of electrons even though Mg exists as an atom in its natural state, not an ion, so how come there are still Mg2+ ions?? And around 4:13, you mention that the smaller ionic radius helps increase attraction and thus the mpt as well, but how? In what way?
Khamees Elbayouk As we go across the period the amount of protons increases, thus increasing the nuclear charge. This makes the ionic radius smaller as there is a greater amount of attraction on the shells ultimately pulling the ion in tighter. This leads to the fact that because the nuclear charge is greater there is greater attraction on the electrons that the metal is bonding with. This means that you'll require a great amount of energy to actually break the bonds increasing the melting points as the attraction is greater.

What an amazing teacher - these videos will be greatly appreciated by many a student for as long as the OCR A Spec is still in existence!
Very kind of you to say so, thank you :)
That was great. My terrible Oxford AQA textbook is useless. These videos are superb.
Wooooo, What a excellent teaching. I salute you Sir. You are my hero in chemistry.
Well structured, organized vedio! It helps a lot!
Han Miao Cheers!
Thank you so much for all of these videos, you make chemistry so enjoyable and easy, thank you!!!!
thank you thank you thank you thank you!!!!!!!!!!
ur explanation is great. thankyou for the video
Watched the video before my exams. Really helpful

it's a good one

Thank you SOO MUCH
Great video man!
very helpful, thank you.
THIS WAS SO HELPFUL! ;_;

OhHaiBrah Ah I see, thanks for explaining! :)
anyone here from Dr Sobala? dab
Welcome!
