   How does atomic radius change from left to right?

   • How does atomic radius change from left to right across a period in the periodic table? The trend in the periodic table is from right to left, and top to bottom, the atomic radii increases.

   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.

   What happens to atomic radii down a group?

   • Atomic radius decreases across a period because valence electrons are being added to the same energy level at the same time the nucleus is increasing in protons. The increase in nuclear charge attracts the electrons more strongly, pulling them closer to the nucleus.

   How does atomic radius change over a period?

   • (Credit: Christopher Auyeung; Source: CK-12 Foundation; License: CC BY-NC 3.0 (opens in new window)) The atomic radius of atoms generally decreases from left to right across a period. There are some small exceptions, such as the oxygen radius being slightly greater than the nitrogen radius.

   How does atomic number affect atomic radii?

   • 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. Moving down a group in the periodic table, the number of filled electron shells increases.

   How does atomic radius affect atomic energy levels?

   • The atomic radius of atoms generally increases from top to bottom within a group. As the atomic number increases down a group, there is again an increase in the positive nuclear charge. However, there is also an increase in the number of occupied principal energy levels.

   Oct 26, 2015 · Explanation: Top to bottom: because as you go down the periodic table, the energy level increases, the electrons (which is negatively charged) orbits further away from the positive nucleus, which means the attraction between the two is weak making the radius bigger.

   Aug 28, 2023 · Atomic radius decreases from left to right within a period. This is caused by the increase in the number of protons and electrons across a period. One proton has a greater effect than one electron; thus, electrons are pulled towards the nucleus, resulting in a smaller radius.
