Who developed the first periodic table?
The German chemist, Lothar Meyer, developed the first Periodic Table in 1864.
In 1869, Russian chemist Dmitri Mendeleev released the Periodic Table.
Mendeleev and Lothar Meyer, a German chemist, were working on creating a periodic table on their own.
Neither was aware of the other's work.
Between 1864 and 1870, Lothar Meyer created multiple Periodic Tables, but he didn't publish them until 1870.
Mendeleev is credited with creating the first Periodic Table because his publication dates back to 1869.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
