How are elements organize?
by their atomic number in the periodic table by grouping the elements on the periodic table
Did Mendeleev organize the elements by atomic mass or atomic number?
Mendeleev arranged elements in order of increasing mass. Later modern periodic table was discovered that contains elements arranged by atomic number.
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 atomic number better than atomic mass for organizing the elements in the periodic table?
Atomic number is a unique number for each element. No two elements have the same atomic number. Atomic number is also the number of protons in the nuclei of the atoms of any given atom. Atomic mass, however, is the number of protons, neutrons and electrons. The number of neutrons can vary with different isotopes of the same element, this means that atomic mass can vary with different isotopes. So atomic number does not vary, but atomic mass does, so it is more logical to use atomic number to organize the elements. In addition, when the elements are arranged according to atomic number into seven rows and 18 columns, it becomes evident that there are certain trends that occur across the periods, and that elements in the same group have similar properties.
What method did Mendeleev use to organize the periodic table of elements?
An element's atomic number, or how many protons it has.
How did later chemists change Mendeleevs periodic table?
They used atomic number instead of Atomic Mass to organize the elements
How are elements organize?

How did chemists organize the elements that were known?
Chemical elements are organized in the periodic table of Mendeleev.
What property of the elements is used to organize th periodic table?
The properties of elements are found to be periodic when arranged according to atomic number. Hence atomic number is considered as base for arranging the elements.
Did Mendeleev organize the elements by atomic mass or atomic number?
Mendeleev arranged elements in order of increasing mass. Later modern periodic table was discovered that contains elements arranged by atomic number.
What is the tool scientists used to organize the elements?
The elements are arranged in the increasing order of their atomic number and repeating properties.
What does the periodic table organize?
The periodic table organizes the elements by atomic number (number of nuclear protons).
How did chemists change Mendeleev's periodic table in early 1900s?
They used atomic number instead of Atomic Mass to organize the elements.
How is the periodic table organize?
The current Periodic Table is organized by each elements atomic number. The atomic number is the number of protons in the nucleus of the atom of each element.
Did Dmitri Mendeleev organize elements by atomic numbers or atomic mass?
At first, he did it by atomic mass, but that didn't quite work out right, so he changed it to atomic number.
Is a periodic table an easier way to organize the elements?
Yes by far. It has many patterns and is organized by the atomic number or the number of protons and electrons.
Which property of an atom's structure was used to organize the periodic table?
The different elements are arranged in the increasing order of their atomic number and repeating chemical / physical properties.
