the number of protons in the nucleus and the number of electrons in the valence orbital
Elements with same property are grouped together. Property can be estimated by its position.
atomic no. or basically according to the no. of electrons in their outermost shell whcih reflect the property of individual atom
Position of Periodic Table describes chemical properties. it is estimated from its position in table.
what property does each of the elements have
What elements are similar to iron in a chemical property on the Periodic Table
Density
Atomic number on the basis of Modern periodic law as on the view of Henry Mosely
atomic number
Atomic number is the fundamental property. Elements are arranged in order of increasing atomic number.
Periodic trends refer to the repeating pattern of properties of elements as you move across a period or down a group on the periodic table. These trends can be recognized by observing how a particular property (such as atomic radius, electronegativity, or ionization energy) changes in a predictable way based on the element's position in the table. By comparing the properties of elements in a specific order, you can identify and analyze periodic trends.
The properties of elements are found to be periodic when arranged according to atomic number. Hence atomic number is considered as base for arranging the elements.
The property used to modify the stacking order of elements on a web page is the z-index property in CSS. It determines the order in which overlapping elements are rendered, with higher values appearing on top of lower values. For z-index to take effect, the element must have a position value of relative, absolute, or fixed.
