We did a styrofoam lab to see what hydrides look like when you move across a period. I wanted to know if I drew the last model correctly for group 15. The directions were confusing. I’m supposed to draw the small yellow circles for the hydrogen and the lines represent valence electrons.

Please help me it would be greatly appreciated:)

"among the transition metal elements, manganese and zinc have a slight lowering of electronegativities. the reason behind this is that the nuclear charges of these elements are slightly weaker than the other transition metal elements due to the way their valence electrons are filled up. both manganese and zinc have their valence electrons filled up to the 4th shell with 1 pair of electrons (4s2) completely occupying it. although the electrons in the 3rd shell (3d) are yet to be paired since the outer most shell is filled up, the ability of the nucleus to attract electrons is lessened. hence,   the electronegativity (or the ability to attract electrons) is lessened."

answer: i dont know the answer but this might

explanation:

the answer is 0.42 is that is an option. this question provides no info
