<u>Mendeleev </u><u>positioned elements in the periodic table in</u><u> increasing order </u><u>of their atomic numbers, such that </u><u>elements </u><u>having identical chemical properties and characteristics plunge into the </u><u>same group.</u>

What is Mendeleev's periodic table called?

  • In order to represent similarities and patterns in the behavior of elements, Mendeleev created the periodic table, which is an arrangement of elements in an increasing atomic mass order in tablet form.
  • Mendeleev stated that "Element characteristics are a periodic function of their atomic weight" in his renowned periodic law.
  • The Periodic Table of Mendeleev is a table that Mendeleev created to list elements in the order of their atomic weights.

  • Mendeleev discovered that there were two elements with atomic weights between 65.2 and 75 because he found it very satisfying that the properties of the elements were more similar and closer to this level.
  • He also imagined having other elements with possessions similar to those of these other elements.
  • In the periodic table, he left a blank for these two elements until they were finally discovered in their true existence.

How does the size change when an atom forms a cation and when an atom forms an anion?
mario62 [17]
<span>A cation is an atom that loses a valence electron. When a valence electron is released there is one electron less to create a repulsive force. The loss of a repulsive force will allow the atom to pull tighter together. An anion would therefore be larger in size due to increased repulsion of the valence electrons.</span>

The definition of heat transfer through convection involves the movement of a fluid that causes heat to move away from a hear source. That being said, convection can take place in a lake, air inside, and air outside since both liquids and gasses are considered to be fluids. I hope this helps. Let me know if anything is unclear.
