What is the formula of the ionic compound formed between chlorine (cl) and aluminum (al)? alcl, because aluminum loses three electrons and chlorine gains three electrons. alcl3, because aluminum loses three electrons and chlorine gains one electron. clal, because chlorine gains one electron and aluminum loses one electron. clal3, because chlorine gains three electrons and aluminum loses one electron. 2- which of the following is a correct formula unit of an ionic compound? al2o3 ca2o mgoh nacl2 3-a student made the lewis dot diagram of a compound as shown. what is the error in the lewis dot diagram? the ca atom should transfer only one electron to cl because the formula is cacl. the number of dots around ca should be one because ca has to transfer only one electron to cl. the ca atom should transfer only one electron to cl, and the second electron should be transferred to another cl atom. the cl atom should transfer two electrons to ca because it has more electrons than ca, so the formula becomes cacl2.
