Electron configuration abbreviated

Often, to save space, electron configurations are shortened the abbreviated electron configuration starts with the preceding noble gas. For the elements sulfur and nickel,... 

Write the symbol and the abbreviated electron configuration of the element described. 

To illustrate these rules, consider the Fe2+ ion. Because the atomic number of iron is 26, this +2 ion must contain 26 — 2 = 24e. Of these electrons, the first 18 have the argon structure the remaining six are located in the 3d sublevel The abbreviated electron configuration is I... 

An abbreviated electron configuration can be written by using the configuration of the next smallest noble gas as follows ... 

Write abbreviated electron configurations for atomic oxygen, selenium, and polonium. 

Because we are not as interested in the noble gas inner core of electrons for sodium atoms as we are in the 3s electron, sodium atoms are often described with the following abbreviated electron configuration, in which [Ne] represents the electron configuration of neon ... 

Tip-off If you are asked to write an abbreviated electron configuration, you can use the following steps. 

For example, to write an abbreviated electron configuration for zinc atoms, we first find Zn on the periodic table (Figure 11.19). 

You can get some practice writing abbreviated electron configurations on the textbook s Web site. 

Write abbreviated electron configurations for (a) strontium, Sr, (b) germanium, Ge,... 

Write abbreviated electron configurations for all of the elements on the periodic table that follow the normal order of filling of the sublevels. 

Write the abbreviated electron configurations for each of the following. 

Which pair of the following ground-state, abbreviated electron configurations corresponds to elements in the same group on the periodic table What elements are they What is the name of the group to which they belong ... 

Write the expected abbreviated electron configuration for the as-yet-undiscovered element with an atomic number of 121. Use Uuo for the symbol of the noble gas below xenon, Xe. (Hint See Figure 11.17.)... 

Electron Configuration and the Aufbau Principle Abbreviated Electron Configurations... 

The use of abbreviated electron configurations, in addition to being faster and easier to write, serves to highlight the valence electrons, those electrons involved in bonding. The s)unbol of the noble gas represents the core, nonvalence electrons and the valence electron configuration follows the noble gas s)unbol. 

Give the abbreviated electron configuration for each atom in Question 3.7. Give the abbreviated electron configuration for each atom in Question 3.8. 

Give the abbreviated electron configuration for each atom in Question 3.7. 

To which element does each of the following abbreviated electron configurations refer ... 

Look carefully at Figure 10.15 and you will see that the p orbitals are full at the noble gases. By placing the symbol for the noble gas in square brackets, we can abbreviate the complete electron configuration and focus our attention on the valence electrons (the electrons we will be interested in when we discuss bonding in Chapter 11). To write the abbreviated electron configuration for any element, go back to the previous noble gas and place its symbol in square brackets. Then list the valence electrons. Here are some examples ... 

Write the abbreviated electron configuration for the following elements ...
