Number of protons.
Elements are ordered by atomic number.
A period in a table is a horizontal row that runs across the table, typically containing data or information related to a specific category or item. Periods help organize the data in a structured manner for easy analysis and comparison.
A period on the periodic table refers to a row of elements that are arranged in order of increasing atomic number. Each period starts a new row and represents the number of electron shells an element has.
Yes.
A period is the horizontal row on the Periodic Table of the Elements
Period 6 of the periodic table consists of 32 elements.
periodsThere are seven periods, or rows, on the periodic table.
There are 8 elements in the third period of periodic table. The elements belong to group-1,2,13,14,15,16,17 and 18
the rows of elements on the preiodic table are called the period. the period tells you the number of electron shells
Dmitri Mendeleev arranged elements on his first periodic table by increasing atomic mass and grouping elements with similar properties together. He left gaps for missing elements and predicted the properties of these undiscovered elements based on their position in the table.

As you move from left to right across period 3 on the periodic table, the atomic radius, metallic character, and reactivity generally decrease. This is because the increasing number of protons in the nucleus leads to stronger attraction for the electrons, resulting in a smaller atomic size and less metallic behavior.
