What does adding one 2s electron for Lithium do to the energy of the 2 p electrons Why does this make sense?

Lithium belongs to atomic number 3 adding 1 electron in the energy shell does not make sense because it will still be unstable.

What energy level are the valence electrons located in lithium?
2nd energy level, the electron arrangement is 2,1 at ground state
How many electrons are gained or lost when lithium becomes an ion?
Lithium is in Group 1A and is a metal, therefore it forms +1 ions in order to achieve a noble gas configuration. For 1A and 2A metals, cation charge = group number or valence number. (they are the same thing).Lithium atom loses one electron to form the cation Li+
Does the addition of two electrons or removal of one electron require more energy for an oxygen atom?
when adding two electrons to the oxygen atom yep! it requires more energy because it has to take them from another atom so it will be removing an electron using more ionization energy to do the work.and we must remember that oxygen needs two electrons to attain its valency then it needs to take two from another atom to be fully filled and without the two electrons it will still lack electron to be stable.this means adding or removing requires energy.
How many electrons in the third shell of lithium?
Electronic configuration of Lithium is 2,1. So in second shell it can hold 1 electron.If it will combine with some other element it will give out its electron in second shell.
Are electrons located in energy levels or electron cloud?
Electrons are located in energy levels within the electron cloud.
What energy level are the valence electrons located in lithium?
2nd energy level, the electron arrangement is 2,1 at ground state
What is the number of unpaired electrons in a lithium atom?
Lithium atoms contain one unpaired electron. Two of the three total electrons in a lithium atom are paired in its lowest energy s orbital, which can contain only two.
Why is it easier to lose electrons from a cesium atom than from a lithium atom?
It all has to due with ionization energy. Ionization energy is the energy required to remove an electron from an atom to make it an ion. Cesium has a lower ionization energy than Lithium, so it is easier to remove electrons, and thus lose electrons, from a Cesium atom than a Lithium atom.
Why the addition of two electrons or removal of one electron requires more energy in oxygen atom?
Type your answer here... when adding an electrons to oxygen it needs more energy in electron affinity in order to attract electrons from other atoms to be stable.and we know that oxygen is in short of two electrons.so in the other hand when an electron is removed from oxygen it will be unstable and will be needing more ionization energy to be able to remove an electron to it.Thus mean indeed when adding or removing electrons for oxygen it requires energy.
How many electrons does lithium lose or gain to achieve a stable octet configuration?
Lithium is in group 1 of the Periodic How_many_electrons_must_the_lithium_atom_give_up_to_become_stable, so it must lose one electron for it to attain a full outermost energy level and become stable.The charge will then be positive (+).
Why does lithium have a higher first ionisation energy than helium?
Helium has a higher ionization energy than in lithium. Further, helium has the highest first ionization energy in all the elements in the periodic table. Lithium has an electronic configuration of [He]2s1. The outer electron is further out and experiences a lower effective nuclear charge. The 2s electron is further out from the nucleus than the 1s electrons in He. Lithium has an atomic radius of 152pm, whereas helium is calculated at 81pm. The effective nuclear charge on the helium electrons is higher than that acting on the 2s electron in Lithium. Estimates vary a little but roughly for helium it is .69 units. For Lithium the effective nuclear charge is 1.3 due to the "shielding" caused by the inner 1s electrons.
If electrons have the most energy in an atom electrons in an electron cloud electrons in the outermost electron shell electrons in the innermost electron shell electrons in the nucleus?
Electrons in the outermost energy shell (valence shell) have the most energy.

Why does lithium have a smaller atomic radius then potassium?
because the second ionisation means removing the second electron from the potassium atom. Potassium only has one electrin in its outer most shell so the second electron would be in another electron shell which is closer to the nucleus meaning there is a stronger attraction to that electron because of the protons in the nucleus which are positive and attrct the negative electrons so more energy is needed to remove the second electron

Electronic configuration of Lithium is 2,1. So in second shell it can hold 1 electron.If it will combine with some other element it will give out its electron in second shell.
What is the electron configuration of the neutral lithium atom?
