Elements on the left side of the Periodic Table become positive when they disassociate (they give up 1 or more electrons), therefore will go to a cathode in an electrolysis tank, so we call them cations. Elements on the right side of the periodic table pick up one or more electrons and become negative. These will go to the positive electrode in a tank, so we call them anions.
If you think that this naming convention is confusing and stupid, that means you are an intelligent right-thinking person. Unfortunately, this idiocy is so embedded we will never be free of it, so learn it and weep.
Besides + and - other differences in ions include how many charges, and how many atoms in the molecular. We have simple elemental Cations such as sodium (Na+), fully ionized calcium (Ca++), and fully ionized aluminum (Al+++). We have simple elemental anions such as chlorine (Cl-), fully ionized sulfur (S--), and fully ionized phosphorus (P---).
Finally, we have ion groups such as sulfur dioxide, (SO2--)
Another left-right periodic table distinction is metallic (left) and non-metallic (right). WARNING. This is a gross oversimplification and is almost as poor as cations-anions.

What are two pure substances?
The two types of pure substance are elements and compounds The two types of pure substance are elements and compounds
Elements on the far left of the periodic table tend to form cations while elements on the far right tend to form anions Explain why this trend occurs?
Elements on the far left of the periodic table need to lose electrons when they ionize, giving them a positive net charge. Conversely, elements on the far right usually gain electrons with the negative charge acquired making them anions.
Do element become more metallic across each period?
No, elements become less metallic across periods. Periods are horizontal rows within the periodic table, and read left to right. The far right elements are called non-metals, and the far left elements are called metals. In between these two groups are a few metalloids - elements that have characteristics of both metals and non-metals. A period looks like this: Metals --> Metalloid --> Non-metals
What are the names of the two types of chambers in an amphibians heart?
Upper two chambers are called atria which are thin walled.Lower two chambers are called ventricles which are thick walled.
Is dinitrogen pentoxide ionic or covalant?
covalent b/c they are both nonmetals. A covalent bond is between two elements on the right side of the periodic table, an ionic bond is between the left and right side.
