What is the Order of elements in the periodic table?
The periodic table is a tabular array of the chemical elements organized by atomic number, from the element with the lowest atomic number, hydrogen, to the element with the highest atomic number, oganesson. The atomic number of an element is the number of protons in the nucleus of an atom of that element.

How many elements are there in Genshin impact?
The Seven Elements. There are seven elements in Teyvat, which are Pyro, Hydro, Anemo, Electro, Dendro, Cryo, and Geo. Each of these Genshin Impact elements has their respective god or Archon and hence, an associated nation.
Who created the periodic table?
The creator of the periodic table, Dmitri Mendeleev, in 1869 began collecting and sorting known properties of elements, like he was playing a game, while traveling by train.
Did Mendeleev's predictions get dismissed?
There were plenty of skeptics and it took years to gain international acceptance, but once newly-discovered elements matched the ones that Mendeleev predicted, his patterns could not be dismissed. In addition, some of the properties that he "fudged" were later recalculated and found to be much closer to his predictions.
Can periodic table games be used for grade?
The periodic table game available on this page is for entertainment purposes only, and should not be used to grade students on their knowledge of chemical elements.
Does the Modern Periodic Table Change? If So, How and Who Does That?
The periodic table as we know it today is managed by the International Union of Pure and Applied Chemistry, or IUPAC (eye-you-pack).
How many elements are in the periodic table?
The table below consists of 118 elements of the periodic table, sorted by atomic number, atomic weight, symbols, density, discovered year and the group.
Who created the modern periodic table?
The modern periodic table is based on the modern periodic law put forward by the English physicist Henry Moseley, which states that “the properties of elements are periodic functions of their atomic numbers”.
What is the atomic number of an element?
The atomic number of an element is equal to the total number of protons in the nucleus of the atoms of that element. The atomic number can provide insight into the electronic configuration of the element. For example, carbon has an electron configuration of [He] 2s 2 2p 2, since its atomic number is 6.
What is the number of protons in the nucleus called?
The number of protons in the nucleus is called the atomic number. The atomic number of each element is unique.
Why is the atomic number of each element unique?
While the atomic number always stays the same some elements have atoms with different atomic mass numbers. This is because some elements have a different number of neutrons in the nucleus.
How to find the mass of an element?
The number of protons and the number of neutrons shall determine the mass number of an element. Since the isotopes of an element have slightly different mass numbers, it calculates the atomic mass by obtaining the mean of the mass numbers for its isotopes.
How can periodic trends be observed?
Periodic trends in the properties of the elements can be observed down the groups and across the periods of the modern periodic table. Every chemical element has a specific atomic number, which provides insight into the number of protons present within its nucleus.
What is the Periodic Table?
The Periodic table of elements is a tool, developed by scientists over hundreds of years. The table lists all the elements that are currently known, in descending order of the number of protons that are present in a single atom of the element.
How to use the Periodic Table
The Periodic Table of Elements can be used in the assistance of chemical calculations, when a specification of an element is needed it is easily found in the Periodic Table.
The History of the Periodic Table
The Periodic Table has constantly been improved and developed over the past 200 years, but in 1869 Dimitri Mendeleev finished the first version of the periodic table as we know it today, by arranging the elements by atomic mass and leaving spaces open for the elements that were not yet discovered.
