Suppose in universe Xacto matter is composed of protons, neutrons, and special matter X. Xs are identical to electrons in every respect except that their spin quantum # ca have any 3 possible values (up,down,or sideways).a. Using condensed spdf notation, give X configurations for all elements with ground states having Xs only in n=1 or n=2 orbitals.b. For elements in a, design and draw a new periodic table that makes sense for this parallel universe. Rows and columns should have the same meanings as in the conventional periodic table. Each square should only contain the abbreviation for that element.c. Which elements in the Xacto universe are most likely to have properties similar to those of their twins in our universe?
