What else can I help you with?
What factors affect energy?
charge, atomic radius, orbital penetration, and electron pairing.
What electron would require the least amount of energy to remove from the atom of sulfur?
This is an electron situated on the outermost level.
What part of the atom is able to be lost or gained?
the energy is require to remove an electron from an atom (ionization energy) but when electron is absorbed in an atom energy is released (electron affinity) however 2nd electron affinity is endothermic ,energy is require.
Is atoms with high ionization energy allow their electrons to be easily taken?
No, atoms with high ionization energy require more energy to remove an electron, making it difficult for them to lose an electron easily. The ionization energy is a measure of the stability of an atom and its tendency to lose an electron.
Define ionization energy of an element?
Ionization energy is the amount of energy required to remove one electron from a neutral atom in the gaseous state. It is a measure of how tightly the electron is held by the nucleus of the atom. Elements with higher ionization energies require more energy to remove an electron and are less likely to form ions.
Why electrons pairing start with only 2p orbital in P subshell?
Electrons pair in the 2p orbital first because each orbital can hold a maximum of 2 electrons, and pairing allows for greater stability due to electron-electron repulsion being minimized. Additionally, electron pairing in the 2p orbital follows Hund's rule, which states that electrons fill degenerate orbitals singly before pairing up.
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.
Explain why the actual electron configurations for chromium and copper differ from those assigned using the aufbau diagram?
The aufbau procedure (filling order of atomic orbitals) is used to work out the electron confiturations of all atoms. However, modification should be made by applying Hund's rule. The aufbau procedure is based on a rough energy levels diagram of many-electron atoms.
What is the electron pairing in the 5s and 4d orbitals of strontium?
In strontium, the electron configuration is [Kr] 5s^2 4d^2. The pairing of electrons in the 5s orbital is due to Hund's rule, which states that electrons fill empty orbitals before pairing up. The 4d orbitals can accommodate up to 10 electrons, with the first 2 occupying separate orbitals before pairing starts.
What electron transition represents a gain of energy?
All transitions in which electrons move from a lower to a higher level require a gain of energy. example: 2nd to 3rd shell
What would require the most energy to remove one electron- F- Ne Na plus Mg2 plus?
The element that would require the most energy to remove one electron is Ne (neon) because it has a full valence shell, making it more stable and less likely to lose an electron compared to the other elements listed.
Elements on the side of the periodic table require large amounts of energy to remove an electron from the outermost energy level of their atoms?
Elements on the right side of the periodic table require large amounts of energy to remove an electron from the outermost energy level of their atoms. It is much easier for them to gain rather than lose electrons.
