2) Draw orbital diagrams (for valence electrons only) for the following ions: a) K+ b) Br-c) Ni2+ d) Zn2+ 3) Define the following terms: atomic radius. Describe the periodic trend for atomic radius. 4) Define Z eff (effective nuclear charge). How does this property affect radii of atoms as you move from left to right in a period? Does it affect ...
CH301 Fall 2010 Worksheet 3 Answer Key: Electron Configurations and Periodic Trends. 1. Match the following elements with their corresponding electron configurations. 2. Write the electron configuration of arsenic (As) in long notation and in short (noble gas) notation.
Does a cation gain protons to form a positive charge or does it lose electrons? Answer. The protons in the nucleus do not change during normal chemical reactions. Only the outer electrons move. Positive charges form when electrons are lost.
This online quiz is intended to give you extra practice in identifying different periodic trends such as atomic radius, ionization energy and electron affinity.

An electron configuration is a method of indicating the arrangement of electrons about a nucleus. A typical electron configuration consists of numbers, letters, and superscripts with the following format: A number indicates the energy level (The number is called the principal quantum number.).
A number of physical and chemical properties of elements can be predicted from their position in the Periodic Table. Among these properties are Ionization Energy, Electron Affinity and Atomic/ Ionic Radii. These properties all involve the outer shell (valence) electrons as well as the inner shell (shielding) electrons.
13 mar 2023 · Know periodic trends of atomic size, ionic size, ionization energy, and electron affinity. Understand the reasons for metallic, nonmetallic, and metalloid character. Understand why some acids dissolve in water to make acidic solution, while others dissolve in water to make basic solutions.
