How has the discovery and usage of the periodic table benefited society? select all that apply. it has enabled scientists to communicate chemical discoveries and results more easily. it has increased scientists' ability to determine how cations and anions form covalent bonds. it has increased scientists' ability to predict and discover new elements. it has led to increased knowledge and usage of elements in technological innovations.

Answer is: It has increased scientists' ability to predict and discover new elements.

Dmitri Mendeleev published a periodic table of the chemical elements in 1869.

Mendeleev noted gaps in the table and predicted then undiscovered elements existed eka-silicon (germanium) and eka-boron (scandium).

For example, germanium discovered in 1886 and it had proporties as Mendeleev predicted.

There are 118 unique substances (elements) arranged on an amazing chart that reveals their hidden secrets to anyone who knows how to read it.  

The first chemical element is hydrogen (atomic number is 1) and the last is oganesson (atomic number is 118).  

Elements are scheduled in periodic table, ordered by their atomic number.  

It has increased scientists' ability to predict and discover new elements.

Explanation:

The arrangement of any thing in a particular order makes us to distinguish one set from other.

For example in library, the books may be arranged based on subjects. So we can identify the particular subject book easily.

In this regard the elements are arranged based on atomic number (in modern periodic table) which leads to arrangement of elements with similar properties in a particular group.

It has increased scientists' ability to predict and discover new elements.
