In the 19th century, some scientists tried to classify the elements by arranging them in order of their atomic weights.
Figure 1 shows the periodic table Mendeleev produced in 1869.
His periodic table was more widely accepted than previous versions.

FAQs

What is the key concept behind Mendeleev’s periodic table acceptance compared with earlier versions?

Mendeleev left gaps for undiscovered elements and arranged elements in a way that improved the table’s explanatory power, leading to wider acceptance than previous versions.

Which ion do all acids produce in aqueous solution?

All acids produce H+ ions in aqueous solution.

How does titration help determine which sulfuric acid sample is more concentrated?

Using titrations with sodium hydroxide, the student compares the volume of alkali needed to neutralise each acid; the acid requiring the larger neutralising volume corresponds to the lower concentration, so the titration results indicate which sample is more concentrated.
