   What is the atomic radius trend in the periodic table?

   • Now we are ready to describe the atomic radius trend in the periodic table. The atomic number increases moving left to right across a period and subsequently so does the effective nuclear charge. Therefore, moving left to right across a period the nucleus has a greater pull on the outer electrons and the atomic radii decreases.

   How do atomic radii change in a periodic table?

   • One atomic radius trend occurs as you move left to right across the periodic table (moving within a period), and the other trend occurs when you move from the top of the periodic table down (moving within a group). Below is a periodic table with arrows showing how atomic radii change to help you understand and visualize each atomic radius trend.

   What is the second atomic radius periodic trend?

   • The second atomic radius periodic trend is that atomic radii increase as you move downwards in a group in the periodic table. For each group you move down, the atom gets an additional electron shell. Each new shell is further away from the nucleus of the atom, which increases the atomic radius.

   What are periodic trends?

   • Periodic trends are specific patterns that are present in the periodic table that illustrate different aspects of a certain element, including its size and its electronic properties. Major periodic trends include: electronegativity, ionization energy, electron affinity, atomic radius, melting point, and metallic character.

   Which group has the largest atomic radii?

   • Atomic radii increase toward the bottom left corner of the periodic table, with Francium having the largest atomic radius. Atoms decrease in size across the period and increase in size down the group. Let’s break down the trend into its period and group trends. There are many trends on the periodic table.

   Sep 20, 2022 · Summary. Atomic radius is determined as half the distance between the nuclei of two identical atoms bonded together. The atomic radius of atoms generally decreases from left to right across a period. The atomic radius of atoms generally increases from top to bottom within a group.
