   How does atomic size change over time?

   • In a group the atomic size increases due to the addition of shells as we move from one period to another. Across a period the atomic size decreases as the number of shells remain the same while the nuclear charge increases. This leads to the pulling of electrons from the outermost shell towards the nucleus thereby decreasing the size.

   What are trends in atomic radii using the periodic table?

   • Figure 10.6a: Trends in atomic radii using the periodic table: (a) The radius of an atom is defined as one-half the distance between the nuclei in a molecule consisting of two identical atoms joined by a covalent bond. In (a) The atomic radius for the halogens increases down the group as n increases.

   Why do atomic radii increase as you go down a column?

   • As you go down a column of the periodic table, the atomic radii increase. This is because the valence electron shell is getting larger and there is a larger principal quantum number, so the valence shell lies physically farther away from the nucleus. This trend can be summarized as follows:

   Why do atoms become smaller over a period?

   • Across a period, the atoms become smaller due to the reason discussed in the section on atomic radius. So, when an electron is added to the valence shell, it will experience higher electrostatic attraction. The electron will move closer to the nucleus, thereby increasing the electron affinity.

   Is there a general trend in a periodic table?

   • Many periodic trends are general. There may be a few points where an opposite trend is seen, but there is an overall trend when considered across a whole row or down a whole column of the periodic table. The first periodic trend we will consider is atomic radius. The atomic radius is an indication of the size of an atom.

   Aug 14, 2020 · In the periodic table, atomic radii decrease from left to right across a row and increase from top to bottom down a column. Because of these two trends, the largest atoms are found in the lower left corner of the periodic table, and the smallest are found in the upper right corner (Figure 8.6.4).

   • Atomic Radius and Ionic Radius Trend. Atomic radius is the distance between an atom’s nucleus and its outermost or valence electrons. On the other hand, the ionic radius is half the distance between two ions that barely touch each other in a compound.
   • Electronegativity Trend. Electronegativity is the ability of an atom to attract electrons . Across a Period. The atoms on the left of the periodic table have less than a half-full valence shell.
   • Ionization Energy Trend. Ionization energy is the minimum energy required to remove an electron from a neutral atom when the molecule is in the gaseous state.
   • Electron Affinity Trend. The electron affinity is the change in energy when an electron is added to a neutral gaseous atom resulting in an anion. When an electron is added to an atom, it releases energy.
