Periodic Trends in Atomic Size
The study of Periodic Trends in Atomic Size delves into the systematic variations in the size of atoms across the periodic table. Atomic size, influenced by factors such as effective nuclear charge and electron-electron repulsion, exhibits predictable patterns as one moves along a period or down a group. Understanding these trends provides valuable insights into the behavior of elements, impacting their chemical and physical properties. This exploration of atomic size variations contributes to a comprehensive comprehension of the periodic table and is fundamental to elucidating the behavior of atoms in different contexts.
Questions
- Why do both atomic size and ionic size increase as you move down a group?
- The diameter of a chlorine atom is 200. pm. How many chlorine atoms are required to line up end to end to stretch a distance of 1.0 mm?
- How do you write the elements #Se, Rb, S# in decreasing atomic size?
- The size of an atom generally increases in what direction on the periodic table?
- What do periodic trends of reactivity occur with the halogens?
- Which are the smallest and largest atoms?
- What periodic trends of reactivity occur with the alkali metals?
- As the elements in Group 17 on the Periodic Table are considered from top to bottom what happens to the atomic radius and the metalic character ofeach successive element?
- The atomic radii of transition metals do not decrease significantly across a row. As you add electrons to the d-orbital are you adding core electrons or valence electrons?
- How does the periodic trend of atomic radius relate to the addition of electrons?
- How is atomic size measured?
- How does atomic radius change from top to bottom in a group in the periodic table?
- Which are the LARGEST atoms?
- Based on periodic trends, which one of the following elements do you expect to be most easily reduced? Ca,Sr,Cl,or P and why?
- What is the order of the atoms #Fe, P, O# in increasing side?
- Does Zeff increase, decrease or stay the same for transition metals in a row?
- Electrons get added on moving through a group as well as period. Then how can the atomic size decrease in a period but increase in a group?
- Is the trend for electronegativity related to the trend for atomic size in the Periodic Table?
- How would you explain how period and group trends in atomic radii are related to electron configuration?
- What concepts describes the reason that atoms are larger and ionization energies are lower as you go down the periodic table?
