Some Helpful Periodic Tables

A couple helpful periodic tables for seeing element discovery dates, electron shells, melting points, etc., which come up periodically (no pun intended) throughout the game.

Summary

Here are some images I found on google that help a lot with some of the objectives. There are plenty of resources that list the properties of elements that you need to know to complete objectives, but some of them are slow to use because they'll show elements in a list (usually sorted by that property) and you then need to translate that to cells to activate in the game,

This make it a lot easier by visualizing those properties on the periodic table themselves, so you can more easily see trends and more quickly match harvesters to the locations with the elements that need them.

Hope they help, and feel free to comment if you find additional (or better) infographics that are useful throughout the game.

Electron Shells

Found in a google image search, this guide can be used to count how many electron shells each period has, and see the number of electrons in the outer shell.

Oxidation States

Found in a google image search. This helpful infographic tells you all the oxidation states each element has.

Discovery Dates

This was one of the most useful charts to me, because it colour codes things in roughly the same groups that the game uses when asking you to activate elements within a specific year range.

Note that a couple of the dates on here disagree with the game by a few years, so if you're having trouble getting an objective to complete, try activating the elements that show up here as being within ~3 years of the objective range.

Melting Points

No explicit numbers here, but it's quite easy to eyeball and quickly activate the elements with approximately the requested meling points to complete the various related objectives.

Highest / Lowest Density Elements

This was a tricky one to find. Again, there are no hard numbers, but you can see the trend - elements towards the borders tend to be less dense than elements towards the center of the table, and density also tends to increase with the row number.
