Anions
The outermost electron shell is called the valence shell. It contains the most reactive electrons because these electrons are farthest from the nucleus and are more likely to interact with other atoms to form chemical bonds.
No that is wrong. that compound has more protons than electrons.
The fluoride ion (F-) contains more electrons than the sodium ion (Na+), as fluoride has 10 electrons in its neutral state whereas sodium has 11 electrons in its neutral state. When fluorine gains an electron to become fluoride, it has one more electron than sodium.
If there is an extra electron in the valence level then the electron is in the excited state and is carrying more energy. If the atom is normal then it is in the ground stte and contains low energy.
If a subshell contains eight electrons, it is likely the p subshell, specifically the 2p, 3p, or higher levels, since p subshells can hold a maximum of six electrons. However, if it contains eight electrons, it suggests that it may be part of a more complex electron configuration involving hybridization or overlapping subshells, such as in transition metals. In this case, the electrons might be distributed across multiple subshells, such as combining p and d subshells. Overall, this indicates a more complex structure of electron arrangement than typical subshell occupancy rules suggest.
Two. An inner shell contains 2 electrons; and an outer shell contains 2 electrons on its near side and 4 more electrons on its outer side. Total of 8 electrons.
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.
The presence of a phenyl group in a molecule increases its electron-withdrawing properties. This is because the phenyl group contains a delocalized pi-electron system, which can withdraw electrons from the rest of the molecule, making it more electron-deficient.
Potassium has one more electron than sodium, as it has 19 electrons compared to sodium's 11 electrons.
Electrons
Potential energy. Potential energy = mass * gravitational constant * height As you see, the further the electron is from the nucleus ( how " high " it is ) the more energy it contains. So, that would be the outer valance electron(s).
NO!!!! Hydrogen has only ONE(1) electron Uranium has NINETY TWO(92) electrons.
