Of what?
Attach a link or pic
Such ions are said to be isoelectronic
No, he is not correct. Xenon is not very reactive since it is located in the group of noble gases. The noble gases are all chemically unreactive gases.Elements within different groups within the periodic table have different physical and chemical properties. Hope this answers the question.
A pictorial drawing represents three sides of an object in a view. An isometric pictorial is a type of pictorial drawing which is built on three lines called isometric axes.Oblique pictorial on the other hand is used to produce two dimensional images of three dimensional objects.
Isometric pictorial are usually drawn on pictorial line sheets, this makes things easier when it comes to sketching pictorial drawings. But in using pictorial line sheets one has to determine the direction at which the edge will be located and the depth that will be befitting for the drawing.
Oblique pictorial use vanish point, which guide the drawer in his drawing, but he has to make some estimations in order to draw a good oblique diagram.
Answer:
Sulfur dioxide (SO2)
⇒ Why is this the best option?
To determine the polarity of the molecule, there are two requirements. The first one has a variety of terminal atoms, whereas the second has a lone pair on the center atoms. The molecule is polar if one of the requirements is met; else, it is nonpolar. The oxygen atom is a terminal atom because it surrounds the sulfur atom, which is the center element in the SO2 molecule's Lewis structure. In this molecule, there are two terminal oxygen atoms. If we look at the first criterion, we can see that it is not met because it calls for the presence of two separate terminal atoms.
