Alkali: Group 1(I A). Halogens: group 17 (VII A)
Answer:
D) Van der Waals
Explanation:
Given that the geometry is linear, one finds that the C = O bonds cancel out any polar effects due to the linear geometry ( O = C = O )and gives the molecule a net dipole of zero. Interactions are therefore dependent upon dispersion forces that are classified as Van der Waal Forces or London Forces.
Phoenicia was a major sea trading power. I'm pretty sure that would be your answer
So what you’re going to do is basically the + and - in each top hand corner is the charge of compound, so for example Li has a charge of +1 while Br has a charge of -1 , to write the formula you need to get the charges to cancel out ( equal zero) so luckily this was easy because -1 +1 =0 ! So it would be LiBr. Though for another example Al has a charge of 3+ while br has a charge of -1 and these do not equal zero, so as a result you have to add more br making the Formula AlBr3! Hope this helps!
The Answer Should be C. Please comment back if im wrong.
