According to the research, the correct option is Mendeleev predicted elements that would later be discovered.
<h3>What is the periodic table of Mendeleev?</h3>
This is the first version of the periodic table and was made up of a column with 63 elements, grouped according to their common properties, and several blank spaces.
Specifically, the Russian chemist Dmitri Mendeleev assumed that some elements that had not been discovered were missing, those corresponding to atomic masses that were not yet known and that allowed the table to have an absolute numerical regularity.
Therefore, we can conclude that according to the research, the correct option is Mendeleev predicted elements that would later be discovered.

The most active metals are the alkali metals which are located in group 1. The most active nonmetals are the halogens, group (17/7)
Specific heat is the amount of heat absorb or released by a substance to change the temperature to one degree Celsius. To determine the specific heat, we use the expression for the heat absorbed by the system. Heat gained or absorbed in a system can be calculated by multiplying the given mass to the specific heat capacity of the substance and the temperature difference. It is expressed as follows:
Heat = mC(T2-T1)
By substituting the given values, we can calculate for C which is the specific heat of the material.
2510 J = .158 kg ( 1000 g / 1 kg) (C) ( 61.0 - 32.0 °C)C = 0.5478 J / g °C
