the diagram below shows a paper clip in front of a mirror.

an upright paperclip sits in front of a vertical mirror. an eye looks toward the mirror from below and left of the paperclip. point 1 is just above the paperclip. point 2 is parallel with point 1 the same distance behind the mirror as point 1 is in front. point 3 is behind the mirror parallel with the center of the paperclip the same distance behind the mirror that the paperclip is in front of it. point 4 is a bit further behind the mirror than point 3.

where will the image of the paper clip appear to the observer?

Hope this helps :))

"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."
