Question

Mendeleev was not the first to arrange elements in a periodic table.
a) True
b) False

Answer 1

Mendeleev was not the first to arrange elements in a periodic table.

Step-by-step explanation:

Dimitri Mendeleev was not the first to arrange elements in a periodic table. This statement is True. Although Mendeleev is widely credited with creating the first periodic table of the elements, it is important to note that German chemist Lothar Meyer independently published a very similar table around the same time. However, Mendeleev is given more credit because his table was published first and because of his key insights regarding the table.
