In the 13th century, no new chemical elements were officially discovered. The scientific understanding of elements during this time was limited, and the concept of elements as we know them today did not fully develop until the 17th century. Most knowledge was based on ancient theories, such as those from Aristotle and alchemical traditions. Therefore, the focus was more on the transformation of materials rather than the identification of distinct elements.

There are 26 transuranic elements that have been discovered so far. These elements have atomic numbers greater than uranium (92) and are all synthetic, meaning they do not occur naturally on Earth.
Over 11 chemical elements have been discovered at Stanford University, including nobelium, lawrencium, and seaborgium.
Approx. 25 chemical elements were known in 1800.

Many elements were not discovered before the 17th century because the technology and scientific methods necessary for their discovery were not yet developed. Additionally, the concept of elements as fundamental building blocks of matter was not fully understood until the advent of modern chemistry in the 18th century.
The 13th century spans from the year 1201 to 1300, while the 21st century covers from 2001 to 2100. To calculate the years between the end of the 13th century and the start of the 21st century, subtract 1300 from 2001, which gives 701 years. Therefore, there are 701 years between the 13th century and the 21st century.
Many of the first discovered elements were named by their discoverer or the location where they were discovered, such as hydrogen, named by Antoine Lavoisier, and uranium, named after the planet Uranus.
Marco Polo discovered India on his voyages in the late 13th century, and brought back many goods and spices. However, it wouldn't be until the 16th century that India would be mapped by European cartographers.
No one knows how many elements are left to discover.
