The Periodic Table of elements is a genius way to categorize the elements. In truth, we could strip the names from each, give them brand new names, and the Periodic table would still be sorted the way it is.
The table gives rise to trends of the elements. Each column denotes the number of valence, or outer shell, electrons that an element has. Each row denotes another full set of electrons. We can predict which elements will bond with which, which elements will form what types of ions (charged elements), and trends like electronegatively, atomic radius, and more!
because the atomic number represents both the number of electrons and protons, and the Atomic Mass is only an average weight of one mole of the substance. The weight of the substance can change depending on the kind of ions an element has. The atomic number is always constant as well.
it was organised to help all chemist have a better understanding of each individual element and also to help connect the similarities between each element and emphasis them. roughly that is the answer but the question itself could be branched off onto more subjects itself. The summary I have used is general not looking at the finer details
Because, that way they would know which ones were missing. The number of protons they have represents their number on the table, hence hydrogen is 1, helium is 2. No two elements have the same amount of protons, thats (the main thing) what differentiates them.
Because atomic number uniquely identifies the element, regardless of isotope or isotopic percentages in a mixture of isotopes. Atomic mass is not unique to an element.
they organised it by grouping things with similar properties together
To categorise the elements into 8 sections.
because it is easier to memorize it that way.
The atomic number is more sure; it is related to umber of electrons, etc. and is specific for a chemical element.
Because the purpose of the periodic table is to display elements according to their chemical and physical properties. These transcend a man-made artefact such as the alphabet!
Elements of the same physical and chemical characteristics are in the same group. Groups are the columns in the periodic table.
Dmitri Mendeleev was a Russian scientist who is credited with creating the periodic table of elements in 1869. He arranged the elements in order of increasing atomic mass and noticed patterns in their properties which led to the periodic law. Mendeleev's work laid the foundation for modern chemistry.
Dmirtri Mendeleev made the first periodic table. It was organized by elements according to the atomic mass. < notice it is atomic mass not number>
The periodic table is organised in order of increasing atomic number so that their properties could be determined in same rows and columns
Both the modern periodic table and Mendeleev's table are organized by increasing atomic number and similar properties are grouped together. They both have periods (rows) and groups (columns) that showcase trends in atomic properties. Additionally, both tables provide a systematic way to predict the properties of elements based on their position.
He organized the elements by the increasing order of the atomic mass.
Mendeleev's periodic table was organized in order of increasing atomic masses. He arranged elements having similar properties together.
Yes, it is correct.
Henry Moseley created current Periodic Table. Elements were arranged in order of atomic number.
The elements arranged according to their atomic number in the table are called periodic table.
The period law states that the elements are the periodic function of their atomic number. Hence they are arranged in order of increasing atomic number.
- the periodic table is organized in periods and groups- chemical elements are listed in the order of the atomic number- the periodic table obey the law of periodicity
Elements of the same physical and chemical characteristics are in the same group. Groups are the columns in the periodic table.
Mendeleev listed the atomic weights and chemical properties of elements as he began to organize them. He noticed that elements with similar properties appeared at regular intervals when arranged by increasing atomic weight.
the original periodic table was based on th elements it had
The Russian. chemist Dimitri Mendeleev in 1869.
the elements in the modern periodic table are arrange in the increasing order of their atomic numbers.
