Awww thank you 💞💞. M still sure that I would've made so many other careless mistakes lolol

what did you guys put for the question on spectrometer, the one that asks about what is P

i wrote that it's the electric field that accelerates the ions but i have a strong feeling it's wrong

what was the answer for the mcq about metallic bonds and ionic compounds.I cant remeber that exactly.
the answer was electrostatic forces right???
did anyone picked this answer

Yup. That's the answer I picked. Not sure if it's right coz one of the other answers in the options was so similar and I was confused.

Your answer is correct. It is the electric field that accelerates the ions by passing them through the charged metal plates.

yeah multiplied by 5

Wasn't it cyclohexane hence 6 bonds?

It's right. You could have mentioned either electric field or negatively charged plates with slits in them

I wrote that it's the magnetic plate of the deflector. Wbu?

UGHHHHHH I put velocity sector because I though that the dotted square as the electric field [facepalm]

I think that you've mistaken between the question under it.

The other option was that both ionic and metallic bonding ' is the attraction between positively charged and negatively charged IONS'. Since metallic bonding is the attraction between delocalised ELECTRONS and ions, both ionic and metallic having
"electrostatic" force was the correct option.
