Atoms of the element selenium (atomic number 34) have the electron configuration
1s2, 2s2, 2p6, 3s2, 3p6, 4s2,3d10, 4p4
What else can I help you with?
Noble gas electron configuration of selenium and phosphorus?
The noble gas electron configuration of selenium is [Ar] 3d^10 4s^2 4p^4 and for phosphorus is [Ne] 3s^2 3p^3. These configurations indicate how the electrons are arranged in the outermost energy levels of the atoms, resembling the stable electron configurations of noble gases.
Why does selenium not have a second electron affinity?
Selenium does not have a second electron affinity because adding an additional electron to selenium would require more energy to overcome the repulsion between the negatively charged electron and the negatively charged selenium ion. In other words, the energy required to add a second electron to selenium is higher than the energy released in the process.
How do you write out the electron configurations of solutions?
Solutions are mixtures of one or more solutes dissolved in a solvent. They do not have electron configurations. Only atoms and ions have electron configurations.
How many filled shells in selenium?
Selenium has 5 filled electron shells. The electron configuration for selenium is 1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p4.
What is the valence electron configuration of selenium?
The valence electron configuration of selenium is 4s2 4p4, meaning it has 6 valence electrons.
Noble gas electron configuration of selenium and phosphorus?
The noble gas electron configuration of selenium is [Ar] 3d^10 4s^2 4p^4 and for phosphorus is [Ne] 3s^2 3p^3. These configurations indicate how the electrons are arranged in the outermost energy levels of the atoms, resembling the stable electron configurations of noble gases.

In other words, the energy required to add a second electron to selenium is higher than the energy released in the process.
Which has the lower electron affinity germanium or selenium?
Selenium has a lower electron affinity than germanium. Electron affinity is the energy released when an atom gains an electron to form a negative ion. In general, electron affinity tends to decrease as you move down a group in the periodic table, which is why selenium has a lower electron affinity than germanium.
How do you write out the electron configurations of solutions?
Solutions are mixtures of one or more solutes dissolved in a solvent. They do not have electron configurations. Only atoms and ions have electron configurations.
What is the chemical makeup of selenium?
The electron configuration of selenium is [Ar]3d10.4s2.4p4.
How Many Valence Electron Does selenium?
Selenium has 6 valence electrons
How many filled shells in selenium?
Selenium has 5 filled electron shells. The electron configuration for selenium is 1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p4.
What is the valence electron configuration of selenium?
The valence electron configuration of selenium is 4s2 4p4, meaning it has 6 valence electrons.
Why do selenium and sulfur have similar chemical properties in terms of electron configuration?
Selenium and sulfur have similar chemical properties because they are in the same group on the periodic table, known as the chalcogens. Both elements have similar outer electron configurations, with sulfur having 6 electrons in its outer shell and selenium having 6 as well. This similarity in electron configuration leads to comparable chemical behavior in terms of oxidation states and reactivity.
What are the examples of elements with predictable electron configurations?
All of the representative elements (s and p block) have predictable electron configurations. However, many of the transition elements have electron configurations that are not predicted by the rules for determining electron configuration.
What is the number of valence electrons in selenium?
Selenium has 6 electrons in its outermost shell.
What is the electron configuration of selenium 2 ion?
Se2- 1s22s22p63s23p64s23d104p6
