In ancient times, the four (or five, depending if you were in Europe or Asia) elements, fire, water, earth, and air (In Asia, it was fire, water, air, wood, and metal) were thought to make up all things. In modern day, elements are still though to compose all matter, but we know that there's a lot more than just four or five (and that none of the classic elements were actually elements, except for metal, which could be an element. Most classical elements are what we now call compounds)

What is the similarities in the modern periodic table and Mendeleev's table?
They have simliar properties and same elements although later on more elements were added to the modern periodic table.=Both periodic tables have elements grouped by similar properties. Mendeleev's periodic table had elements arranged in order of increasing atomic mass in columns with similar properties. While many of the elements are in order of atomic mass on the modern periodic table, some are not, as the modern table has elements arranged in order of increasing atomic number.=
What do vertical colums represent in the periodic table?
Physical and chemical properties change somewhat regularly across a period. Elements that are close to each other in the same period tend to be more similar than elements that are father apart.
How did Antoine Lavoisier develop the modern definition a chemical element?
Antoine Lavoisier developed the modern definition of a chemical element by recognizing that elements cannot be broken down into simpler substances through chemical means. He conducted numerous experiments to determine the conservation of mass during chemical reactions, leading to the concept of the conservation of matter and the identification of elements as the basic building blocks of matter.
The modern periodic table elements are arranged?
The modern periodic table arranges elements based on their atomic number, which is the number of protons in the nucleus. Elements with similar chemical properties are grouped together in columns called groups or families. The table is divided into periods (rows) that indicate the number of electron shells in an atom.
In the modern periodic table what elements are listed in vertical columns?
Elements in vertical columns in the modern periodic table are known as groups. They share similar chemical properties due to having the same number of electrons in their outermost energy level. Each group is characterized by a specific number of valence electrons.
What is different about the ancient and modern definition of elements?
In ancient times the elements meant : water, fire, earth, and air. However the modern definition of elements is a pure substance that cannot be broken down into a simpler substance.
How is the modern periodic table similar to the Mendeleev periodic table?
Both arrange elements in groups of elements having similar properties.
