This is how I memorized the ionic formulae. It is a lot to remember, so it does take some time and studying. But this website helped me learn it fast and in a suuuper unique way. I learned it 3 years ago and could still name quite a bit of them. Hope this helps!!!
Using the Fundamental Equation of Calorimetry, we have:

Answer:
All the members of a group of elements have the same number of valence electrons and similar chemical properties.
Explanation:
The vertical columns on the periodic table are called groups or families because of their similar chemical behavior.
In the early 1900s, a scientist named Alfred Wegener noticed how the continents seem to fit together and developed the Theory of Continental Drift. Continental drift is the theory that continents can drift apart from one other and have done so in the past. Wegner's theory also explained why fossils of the same plant and animal species are found on both sides of the Atlantic Ocean. In addition similar types of rock and evidence of the same ancient climatic conditions are found on several continents.
Wegner hypothesized that all the separate continents of today were once joined in a single landmass that he called Pangaea.
