[@TheSeppukiri]

In many past paper questions, when you have to draw an example of metallic bonding, the markscheme says the amount of delocalised electrons you draw has to correspond to the amount of ions you draw and the charges on the ions to get the full marks, so for example, if you draw 6 Mg 2+ ions in a metallic structure, you need to draw 12 e-'s in the "Sea" of electrons to get full marks, I've lost marks in mocks because of this before

[@sofipaezamaya8798]

sorry for my stupid question, I'll start a levels this September so I am just getting ready for it. why 12 e-??? 🙈 is it because is 2+ so is 6 x 2? but why is 2+? because Mg is 2+??? thank you

[@TheSeppukiri]

+Sofi Paez Amaya Yeah, when magnesium forms ions, it loses 2 (negatively charged) electrons and as a result has a 2+ positive charge. This means every magnesium ion contributes 2 electrons to the "sea" of electrons involved in metallic bonding, so if there are 6 ions, there will be 12 electrons in this sea

22.41 wouldent you just say, 'because its 2 non metals?'

[@mohammadsultan639]

+Mohamed Maxamed Nah because it says deduce not explain which implies that you have to use your knowledge to work it out. Why do 2 non metals form covalent bonds? because its made of non metals and non metals have small differences in electronegativity so they share a pair of electrons rather than accept or donate them.

[@MrERintoul]

Abz Abzy That's a bit of a strange example in that in this case, the difference in electronegativity means that it is in fact covalent, not ionic. What paper was it from?

[@supersimple1686]

26:05 you mention weak vdw forcxes for iodine, but its boiling point is 184 degrees, so how does it vaporise under light heat?

[@nikkinyarko]

You see when in the case of co ordinate bonding, when Nitrogen gave both of its electrons to hydrogen, what happened to the electron hydrogen already had?

[@arbabqamar9941]

It didn't have any hence why nitrogen donated 2

[@yask7982]

what is the initial difference between knowing if it has a high melting point or high boiling point?

[@MrERintoul]

+Yas K Generally speaking, it depends on the state of the substance at room temperature. We probably aren't as bothered about metals having a high boiling point as they are solid at room temperature and so we have to melt them before we get to that stage. Do you get me?

[@livelife1823]

GREAT VIDEOS FOR REAL but for 4 (d) , if I put strong electrostatic attraction between oppositely charged electrons and ions , would I get it correct ?

[@MrERintoul]

+live life If you are referring to the magnesium oxide question then NO. NEVER. DON'T DO IT. The attraction is NOT between the ions and electrons. If the question was asking about the crystal type in magnesium then yes, your answer would be great. BUT IT ISN'T.

why do we talk about the intermolecular attraction when explaining BP for iodine but covalent bonding for explaining MP for graphite?

[@arhamshahzad9491]

Iodine doesnot melt when heated, it vaporises due to break of weak Van Dar Waal when supplied little energy. That's what makes it a sublime substance

[@Ambrosia223]

If its a 2 marker asking you what makes Al a better electric conductivity than Na, is it because of more electrons given out per ion thus there are more electrons passing the charge?
