Mendeleev reversed some pairs of elements in his Periodic Table to maintain the proper order of increasing Atomic Mass, which allowed for a more coherent grouping of elements with similar chemical properties. He prioritized the similarities in chemical behavior over strict adherence to atomic mass in cases where it led to inconsistencies, such as with iodine and xenon. This decision helped to highlight trends and relationships among the elements, ultimately contributing to the development of the periodic law.
What else can I help you with?
Is he following true or false Atoms of some elements can share three pairs of electrons?
True. Atoms of some elements, particularly nitrogen and phosphorus, can form triple bonds by sharing three pairs of electrons with other atoms. This type of bonding allows for the formation of stable molecules, such as nitrogen gas (N₂), where each nitrogen atom shares three pairs of electrons with the other.
How many places on the periodic table are the elements not in order by increasing atomic mass?
Classical pairs ate tellurium-iodine, thorium-protactinium, uranium-neptunium; and also some transuranium elements.
Does zinc normally exists in pairs?
Zinc typically exists as a single atom in its elemental form and is not found in pairs like some diatomic molecules (e.g., oxygen, O2). In nature, zinc usually occurs in compounds, often in combination with other elements such as sulfur or oxygen, rather than as diatomic pairs. In biological systems, zinc ions (Zn²⁺) play crucial roles but are also not paired in the same way as diatomic gases.
Are transition elements radioactive?
Some are, and some are not.
Is cromosoomau are single or in pairs?
Chromosomes are usually found in pairs in most organisms, with one chromosome inherited from each parent. Humans have 23 pairs of chromosomes, for a total of 46 chromosomes. Exceptions do exist, such as sex chromosomes in some species.
Which pairs show process that the reverse of one another?
some one answer it lol
Why did Dmitri mendeleev reverse the order of some elements in the periodic table?
He was bold enough to reverse the order of some pairs of elements and to predict that their atomic masses were incorrect. Some of these predictions were correct, but others were not, because we now know that the fundamental basis of the periodic table is atomic number rather than atomic mass.
Can atoms of some elements can share three pairs of electrons?
yeap!
What are some pairs of numbers such that the product of the 2 numbers is the reverse of the sum of the 2 numbers?
9-9

This type of bonding allows for the formation of stable molecules, such as nitrogen gas (N₂), where each nitrogen atom shares three pairs of electrons with the other.
Is atom of some elements can share three pairs of electrons?
The elements carbon and nitrogen can share 3 pairs in a triple bond. Carbon in alkynes, e.g. ethyne (acetylene) and nitrogen in N2 There ar also some transition metal complexes where triple bonds are formed betwee two transition metal atoms.
Atoms of some elements can share three pairs of electrons. True or false?
True. Nitrogen can share three pairs of electrons and has a lone pair of electrons for a total of eight in it's valence shell
How many places on the periodic table are the elements not in order by increasing atomic mass?
Classical pairs ate tellurium-iodine, thorium-protactinium, uranium-neptunium; and also some transuranium elements.
What is pairs elements that is would most likely form non polar convalent bonds?
Elements that are close to each other on the periodic table typically form nonpolar covalent bonds, as they have similar electronegativities. Some examples of pairs of elements that would most likely form nonpolar covalent bonds include carbon-carbon (C-C), hydrogen-hydrogen (H-H), and chlorine-chlorine (Cl-Cl).
What are elements that come in pairs?
Such elements are called "diatomic." There are exactly seven of them: • Bromine (Br) • Chlorine (Cl) • Fluorine (F) • Hydrogen (H) • Iodine (I) • Nitrogen (N) • Oxygen (O)
How many pairs of underwear should a guy own?
There is not a limit on how many pairs of underwear a guy should own. Some guys have only 7 pairs and some have 50.
Do conures come in pairs?
Some Conures when you buy them do come in pairs but others they come individually.
