Where are the metal located in the periodic tabel?

Metal is located throughout the periodic table. The periodic table is based on atomic weight. Metals range from some of the lightest to the heaviest of elements.


What characteristic was used to organize the first periodic table?

Mendeleev arranged the periodic table according to increasing atomic mass. This method has been used since he first developed it in the 1800s.


What is the number on the periodic table?

The large number on the periodic table is the atomic number. There is a smaller number that is the atomic weight. For example, Titanium's atomic number is 22 and its atomic weight is 47.867.


What number is the periodic table based on?

What is the difference between the periodic table and Mendeleev's table?

The periodic table is a chart that organizes elements based on their properties and atomic structure. Mendeleev's table was an earlier version of the periodic table that arranged elements by atomic weight and grouped them by similar properties. Mendeleev's table also left gaps for undiscovered elements, predicting their properties accurately.


Is your modern periodic table based on atomic mass or atomic number?

The modern periodic table is arranged according to the elements' atomic numbers.


State the periodic law on which Mendeleev's Periodic table was based and why and how this periodic law changed?

Mendeleev's Periodic Table was based on the periodic law which states that the properties of elements are a periodic function of their atomic masses. This law changed with the discovery of atomic number by Moseley which stated that the properties of elements are a periodic function of their atomic numbers, leading to a more accurate and modern periodic table based on atomic number.


What are the elements in the periodic table based on?

Atomic Number


The periodic table is based on an element's what?

The periodic table is based on an element's atomic number, which is the number of protons in the nucleus of an atom. Elements are arranged in order of increasing atomic number, which also dictates their unique placement in the periodic table.
