Rendering the periodic table in C++ using SFML
Looking at the code you've posted here, it's pretty straightforward and I'm able to understand what it does. That's great! I have a few suggestions on how to improve it.
Named Types
One common complaint about the standard template library and templates in general in C++ is the ridiculously long type names that result from using them. I see that in your code here. It's easily solved by creating new named types that represent the common types you use. For example:
std::vector&lt;std::shared_ptr&lt;sf::Drawable&gt;&gt;

uses 3 types with namespaces. If you did this:
typedef std::shared_ptr&lt;sf::Drawable&gt; sharedDrawable;

Then your new type becomes:
std::vector&lt;sharedDrawable&gt;

Or even better, use the new using directive in C++11:
using sharedDrawableVector = std::vector&lt;std::shared_ptr&lt;sf::Drawable&gt;&gt;;

Or something along those lines.
Use C++!
You're writing in C++, but you're using older methods of iterating through containers. In the destructor of Element you're going through the list manually when you could use a std::find() method instead.
Magic Numbers
In the constructor of Element you create a vector with coordinates &lt;49, 49&gt;. What does it mean? What is it? Why &lt;49, 49&gt;? You should create a constant with a name that describes what this represents:
const sf::Vector2f kRectOriginVector {49, 49}; // Or whatever it means

Then use that in the constructor.
