Question

1. using the periodic table as a model, which prediction about element w (in group 12) is most likely correct? element w will have 7 valence electrons and tend to form w - ions. element w will have 17 valence electrons and form w¹⁷⁺ ions. element w will have 8 valence electrons and not form ions. element w will have 7 valence electrons and form w⁷⁺ ions.

Explanation:

Elements in Group 12 have 2 valence electrons. They tend to form +2 ions by losing these 2 valence electrons. However, looking at the options provided, we know that elements in Group 17 have 7 valence electrons and form - 1 ions. None of the options are correct based on the properties of Group 12 elements, but if we assume a mis - identification and think about Group 17 elements: elements in Group 17 have 7 valence electrons and form $W^{-}$ ions to achieve a stable octet.

Answer:

None of the provided options are correct for a Group 12 element. If considering Group 17 elements, the correct statement would be that an element in Group 17 will have 7 valence electrons and form $W^{-}$ ions. But among the given options, there is no correct answer for Group 12.
