Why would you expect the VSEPR class AX3E3 would not exist?

Note: different VSEPR families do not have the same number of members. (The members of each family are the VSEPR classes that belong to that family. For example, thenext VSEPR class of the AX6 family after AX4E2 would be the hypothetical AX3E3. This would require a central atom with nine valence electrons to combine with threeelectrons contributed by three X atoms to give a total of 12 electrons on the central A atom. So why would you expect that the VSEPR class AX3E3 would not exist?

Answer #1

No atom was found with nine valence electrons but VSEPRclass AX3E3 requiares nine valece electrons.So no ato can form VSEPR class AX3E3 type ofcompounds.

The maximum no. of valence electrons for an atom are 8.Noble gases have eight valence electrons. All the remaining atomshave less than eigth valence electrons.

It's magical like a unicorn and cannot exist anywhere, not even in outer space.

    Objectives You will implement and test a class called MyString. Each MyString object keeps track of a sequence of characters, similar to the standard C++ string class but with fewer operations. The objectives of this programming assignment are as follows. Ensure that you can write a class that uses dynamic memory to store a sequence whose length is unspecified. (Keep in mind that if you were actually writing a program that needs a string, you would use the C++ standard...
