Which of the following is a CORRECT guideline when writing the IUPAC chemical name of a binary compound from a chemical formula?
A
Binary compounds generally end with an –ite.
B
Binary ionic compounds are always named using the positive ion followed by the negative ion.
C
The metal anion is named first, followed by the non-metal cation.
D
Roman numerals are used to indicate the number of each atom in the formula.

Astudent made the lewis dot diagram of a compound as shown. mg is written with two dots shown on its top. an o is written on each side of mg. each o has six dots around it. an arrow is shown from one dot on mg toward the vacant space around the o on the right. another arrow is shown from the other dot on mg toward the vacant space around the o on the left. the title of the art is students lewis dot model. what is the error in the lewis dot diagram? an o atom should transfer all its six electrons to mg because the formula is mgo. both electrons of mg should be transferred to one o atom because the formula is mgo. the electrons should be transferred from each o atom to mg because mg has fewer electrons. the number of dots around mg should be four because it has to transfer two electrons to each o.
