Sodium. Its found in all food everyday when in the compound NaCl, yet pure sodium will cause a giant explosion when placed in water.

How did chemists change Mendeleev's periodic table in early 1900s?

They used atomic number instead of Atomic Mass to organize the elements.


Why is the mendeleevs table called the periodic table?

Because the properties of the elements change in a periodic fashion. In the early versions, when fewer elements were known, the chemically similar elements were thought to occur every eight positions.


How were elements arranged on the early Periodic Table of Elements?

before it there was no organization, but the first periodic table was organized by atomic mass.


Who discovered single replacement reaction?

Single replacement reactions were not discovered by a single individual, but rather understood and classified as part of the broader study of chemical reactions over time. These reactions, where one element replaces another in a compound, were recognized by early chemists such as Antoine Lavoisier and John Dalton in the 18th and early 19th centuries. The systematic study of chemical reactions, including single replacement, evolved with advancements in chemistry and the development of the periodic table.


1.Why did Mendeleev leave gaps in his early periodic table and what was the ultimate importance of the gaps?

Mendeleev left gaps in his early periodic table to accommodate elements that had not yet been discovered but were predicted to exist based on the periodic trends he observed. By doing so, he demonstrated the periodic nature of elements and their properties, which allowed for the prediction of the characteristics of these unknown elements. The ultimate importance of these gaps was that they validated the periodic law and underscored the predictive power of the periodic table, leading to the eventual discovery of elements like gallium and germanium that fit into the predicted spaces.

How did chemist change mendeleevs perioic table in the early 1900s?

Chemists in the early 1900s made changes to Mendeleev's periodic table by rearranging elements based on their atomic number instead of atomic mass, leading to the development of the modern periodic table. This change accurately emphasized the relationship between an element's properties and its atomic number, rather than its atomic mass, and helped to better organize the elements.

What did Mendeleevs periodic table look like?

It looks the same as it did when Mendeleev created it. There are no changes made to the table throughout the years because Mendeleev had predicted the correct placement for all of our current known elements.


What was different about how the alchemist and the early chemists communicated their knowledge?

The knowledges were often communicated encoded.


Why did scientist failure to make gold?

Early chemists and alchemists were using chemical energy to try to transmute (change) other metals to gold. There is far too little energy in chemical reactions to do this.


What were the predecessors of today's chemists?

The predecessors of today's chemists were alchemists, who originated in ancient civilizations and focused on transforming substances into gold or discovering the philosopher's stone. This early form of chemistry laid the groundwork for the scientific principles and methods used by modern chemists.


Why couldn't early scientist explain mass changes during reactions?

Early chemists knew that atoms were very small but had no way of actually finding their mass.

Who is mendeleev and Meyer?

Dmitri Mendeleev and Julius Lothar Meyer were two chemists who independently developed early versions of the periodic table of elements in the 1860s. Mendeleev is often credited with creating the first widely recognized periodic table, organizing elements by their atomic mass and predicting the properties of undiscovered elements. Meyer also arranged elements based on atomic volume and demonstrated periodic relationships, but Mendeleev's table included predictions that later proved accurate, solidifying his legacy in the field of chemistry. Both contributions were crucial in understanding the organization of elements in chemistry.
