Tabla periódica

The periodic table is structured so that the atomic number of elements increases by one across each row. Elements in the same column share similar properties. Although the table's layout has evolved over time, its fundamental design has remained consistent since Dmitry Mendeleev's creation in 1869.

How is the periodic table organized in terms of atomic numbers?

• By increasing atomic number

• By alphabetical order

• By increasing atomic mass

• By element density

What is a common characteristic of elements in the same group on the periodic table?

• They have the same atomic number

• They have similar properties

• They are in the same period

• They have the same atomic mass

Who is credited with creating the basic shape of the periodic table?

• Albert Einstein

• Isaac Newton

• Marie Curie

• Dmitry Mendeleev

In what year was the periodic table's basic shape created?

• 1905

• 1869

• 1801

• 1923

How has the periodic table changed over the years?

• It has been replaced by a new system

• Its distribution has changed, but the basic shape remains

• It has remained exactly the same

• Its basic shape has changed completely
