What did organizing information on the periodic table reveal?
Periodic patterns and trends
Who was the Russian scientist who discovered a set of patterns that apply to all elements?
Dmitri Mendeleev was the Russian scientist who discovered the periodic law and created the first version of the periodic table in 1869. He arranged the known elements by their atomic mass, demonstrating a periodic arrangement of properties that revealed recurring patterns.
Who placed all elements in right place according to properties?
In 1869, Dmitri Mendeleev created the first full version of the Periodic Table, including all known elements and leaving places for:Ekaboron or scandiumEkaaluminium or galliumEkamanganese or technetiumEkasilicon or germaniumScientists continue filling up the table as new elements are found, a process that goes on today.
What is a description of the periodic table?
In 1869 Russian chemist Dimitri Mendeleev formulated the periodic law, which stated that properties of elements recurred in a pattern. Based on this, he also helped develop the periodic table, predicting the discovery of multiple elements rather accurately.
What do you now know to be the basis for the observations that Henry Moseley made about the pattern of Xray frequencies emitted from elements?
Henry Moseley's observations were based on his discovery that each element emits X-rays with a unique frequency that corresponds to its atomic number (number of protons). This revealed that the atomic number, not the atomic mass, is the fundamental property that determines an element's chemical behavior and its place in the periodic table.
What is the pattern in repeating the properties of elements revealed in the periodic table?

In 1869russian chemist developed a way to classify the elements in a table.?
In 1869, Russian chemist Dmitri Mendeleev developed the periodic table of elements, organizing them by increasing atomic mass and grouping elements with similar properties. This innovative classification system revealed periodic trends and allowed for the prediction of undiscovered elements. Mendeleev's work laid the foundation for modern chemistry, as it established a systematic framework for understanding elemental relationships.
How was the discovery of the protons initiated the development of the periodic table of elements?
The discovery of protons helped scientists understand the atomic structure of elements. By knowing that each element has a specific number of protons in its nucleus, scientists were able to organize the elements based on their atomic number, which led to the development of the periodic table. This organization revealed patterns in the properties of elements and facilitated the prediction of properties of undiscovered elements.
Has chemical analysis of lunar rocks shown that chemical elements not listed in the periodic table exist on the moon?
No, elements are defined by the number of protons they have and the periodic table contains all the elements up to over 100 protons, much past this point they become very unstable and radioactively decay into lighter (less protons in the nucleus) atoms. Elements this heavy do not occur naturally so we would not find them on the moon.
How does the periodic table work-?
The layout of the periodic table demonstrates recurring ("periodic") chemical properties. Elements are listed in order of increasing atomic number (i.e. the number of protons in the atomic nucleus). Rows are arranged so that elements with similar properties fall into the same vertical columns ("groups"). According to quantum mechanical theories of electron configuration within atoms, each horizontal row ("period") in the table corresponded to the filling of a quantum shell of electrons. There are progressively longer periods further down the table, grouping the elements into s-, p-, d- and f-blocks to reflect their electron configuration. In printed tables, each element is usually listed with its element symbol and atomic number; many versions of the table also list the element's atomic mass and other information, such as its abbreviated electron configuration, electronegativity and most common valence numbers. Hope this helps.

What is the history of the periodic table of elements?
hi! i will give u the answer later in my science book!Or...Here's something I put together for a chemistry homework I did the other day:A History of the Periodic TableThe History of the Periodic table has been one of constant evolution and development. Arguably beginning with Antoine Lavoisier, who wrote the first extensive list of some 33 elements in 1789, the Periodic Table's history then stretches all the way to the 1940s with Glenn Seaborg's contributions. It has even been estimated that there are still a few more elements to be discovered and added to the table.The actual idea of elements which the world consists of was thought of by Aristotle around 330 BC. He came up with the theory that there were four elements or "roots" as they were known: Earth, Air, Water and Fire. While the idea of there being a limited number of chemical elements from which everything in the world is composed of is a more modern idea, people from as far back as ancient times have been aware of certain, easier to mine, chemical elements such as gold, silver and copper.The first chemical element to be discovered and recorded was phosphorus, the finding of which was entirely coincidental. It was in pursuit of the "philosopher's stone" - a mythical object - that the bankrupt German merchant stumbled across a glowing substance when distilling urine in 1649. He kept his discovery secret until it was rediscovered in 1680 and made public by Robert Boyle. Boyle decided that an element was a subject that cannot be broken down into a simpler form by a chemical reaction. This tangible definition remained official for almost 300 years.Lavoisier's list in 1789 was the next major landmark in the Table's development. Although the list classified elements into two categories (metals and non-metals), it included light which he believed to be a material substance.The Swedish chemist Jöns Jakob Berzelius then created a table of atomic weights, introducing letters to symbolise elements, as well as identifying a few of his own, including silicon and cerium. Much of his work was done in around 1828.Also around this time, Johann Döbereiner, began to classify the known elements further, realising that some of them could be placed in groups of 3 which had related properties. He called these groups "triads", an example being lithium, sodium and potassium.Later, in 1865, the Englishman John Newlands put the 56 elements discovered at the time into 11 groups, again based on similar physical properties. He suggested the "law of octaves", and was a forerunner to the notion of periods.Shortly after, a Siberian-born chemist by the name of Dmitri Mendeleev, made another considerable change to the Periodic Table. He produced a table based on atomic weights, although arranged them "periodically", placing elements with similar properties underneath each other. He allowed space for elements that were unknown at the time and their predicted properties. He re-arrange the order of elements if their properties required it, eg, tellurium is heavier than iodine but comes before it in the Periodic Table.William Ramsay discovered the noble gases towards the end of the 19th century. He removed oxygen, nitrogen, water and carbon dioxide from a sample of air, which left him with a gas 19 times heavier than hydrogen, very unreactive and with an unknown emission spectrum. He named it Argon. Going on to discover helium, krypton, xenon and neon he revealed a new group of elements in the Periodic Table and won a Nobel Prize in 1904.In 1914, Henry Moseley altered the 'Periodic Law' so that the properties of the elements varied periodically with their atomic numbers.The last major contribution to the periodic table was Glenn Seaborg's synthesising of the transuranic elements (the elements after uranium in the periodic table) in 1940.The Celtic Roman
