Question

Quizplus · Accepted Answer

Eka-aluminum refers to gallium, which has an atomic number of 31. Therefore, its predicted formula would be XCl3, based on its group in the periodic table. However, since gallium can also form compounds with higher coordination numbers, the actual formula can vary. The closest option to XCl3 is C, which suggests a formula of XCl₃ (where S = sigma bond and U = unshared electron pair).
