Questions:

1 . Why were noble gases previously classified as group zero of the Periodic Table? Why are they now classified as Group VIII? What metals are called noble? Why?
2 . Prepare a message on the topic “Inert or noble?”
3 . What chemical bond is called ionic? What is the mechanism of its formation? Is it possible to talk about a “pure” ionic bond? Why?
4 . What are cations? What groups are cations divided into?
5 . What are anions? What groups are anions divided into?
6 . Why is it customary to divide ions into hydrated and non-hydrated? Does the presence of a hydration shell affect the properties of ions?
