Based on position in the periodic table and electron configuration, arrange these elements in order of decreasing E_ i1
I don't understand the symbolism.
To arrange elements in order of decreasing ionization energy (E_i1), you need to consider their positions in the periodic table and their electron configurations. Ionization energy refers to the energy required to remove an electron from an atom or ion.
Here is a step-by-step guide to arranging elements in decreasing order of ionization energy:
1. Start by looking at the periodic table and find the elements in question. You can refer to a printed periodic table or use online resources.
2. Identify the elements and their electron configurations. The electron configuration describes how the electrons are distributed in energy levels or orbitals around the nucleus of an atom.
3. Pay attention to the following patterns:
- Ionization energy generally increases as you move across a period from left to right in the periodic table. This increase occurs because atoms have a higher effective nuclear charge (more protons in the nucleus) as you move across a period, making it more difficult to remove an electron.
- Ionization energy generally decreases as you move down a group or column in the periodic table. Down a group, the number of energy levels or shells increases, and the electrons are further away from the nucleus, experiencing less attraction and thus requiring less energy to remove.
4. Use these patterns to arrange the elements. Compare their positions in the periodic table and consider their electron configurations. Elements further to the right and closer to the top usually have higher ionization energies.
5. Arrange the elements in order of decreasing ionization energy based on your analysis.
Keep in mind that there can be exceptions and anomalies caused by factors like electron-electron repulsion and electron shielding. However, the above guidelines will provide a general understanding of how to arrange the elements based on decreasing ionization energy.
