Answer:

The answer to your question is:  Fluorine, Chlorine, Bromine, Iodine

Explanation:

Electron configuration              ns² np⁵

We observe that this electron configuration finishes in "p". Elements from groups IIIA to VIIIA finish their electron configuration in "p".

Elements in Group IIIA    finish in p¹

                    Group IVA    finish in p²

                    Group VA    finish in p³

                    Group VIA   finish in p⁴

                   Group VIIA  finish in p⁵

                    Group VIIIA finish in p⁶

Then, the list of elements with this electron configuration is:

Fluorine, Chlorine, Bromine, Iodine

I need help understanding this problem and the answer.
victus00 [196]

Answer:-

1440 cases

Explanation: -

We are told that 1 pallet = 45 bundles.

We are also told that 1 bundle = 32 cases.

We need to find how many cases are there in 1 pallet.

1 pallet = 45 bundles (First conversion factor)

= 45 x 32 cases (second conversion factor)

=1440 cases

Thus we see that 1 pallet has 1440 cases. We needed to use two conversion factors for this, first to convert pallet to bundle and second to convert bundle to cases.
