| whats another name for a positive ion? | Cations. |
| what are cations? | it is formed when an atom loses electrons. |
| why does the atom form a cation? | Due to the emptiness of its outermost shell. |
| From which type of atoms do cations mostly come from and why? | they mostly come from metal atoms because metal atoms have few electrons in their outermost electron shell and these electrons are weakly bound to the atom. |
| What is an anion? | It is produced when an atom gains electrons.This will occur if the outermost electron is almost full.so it gains electrons until the shell is filled. |
| where do anions come from? | All anions come from non-metallic atoms. |
| What are ionic compounds? | It is when cations and anions come together they are made up of large crystal lattices. |
| how do you name an ionic compound? | you write the name of the cation followed by the name of the anion. |
| What happens when cations come close to anions? | they stick together forming an ionic bond. |
