Yes, nuclear fission reactors are very effective and can generate a lot of power. That is why nuclear fission reactors are very effecive
Transitions between various stages of electron excitement.
The force that is most effective over the longest distances are nuclear forces. Strong nuclear forces and weak nuclear forces. Gravity is the weakest of the four.
The weak nuclear force
the effective storage and disposal of nuclear waste
Electron shielding decreases the effective nuclear charge.

(A)Fluorine due to its high effective nuclear charge (B)Fluorine due to its low effective nuclear charge(C) Francium due to its great amount of shielding (D)Francium due to its low amount of shielding .(answer choices)
a) How is the concept of effective nuclear charge used to simplify the numerous electron-electron repulsions in a many-electron atom?Effective Nuclear Charge- the (net) positive charge experienced by an electron in a many electron atom. This charge is not the full nuclear charge. It accounts for the shielding of the nucleus by other electrons in the atom.The nucleus is surrounded by electrons. These electrons are shielded from the nucleus by electron repulsions. The effective nuclear charge is less than the actual nuclear charge because the repulsions of the electrons needs to be taken into account.This is done in the equationZeff = Z (protons) - S (screening constant, the inner core amount of electrons)b) Which experiences a greater effective nuclear charge in a Be atom, the 1s electrons or the 2s electrons?The 1s electrons would have a greater nuclear charge. The number of electrons between the 1s electrons and the nucleus is less than the number of electrons between the 2s electrons and the nucleus. This means the screening constant is larger. When you subtract the larger amount of electrons from the amount of protons, 4, the difference will be less, meaning the value of the effective nuclear charge will be less.
Effective nuclear charge is the net charge of an electron in an atom.Z(eff) = Z - S where:Z - atomic numberS - number of shielding electrons
Yes, when an effective nuclear charge increases it does pull the electrons closer to the nucleus. An electron is a negatively charged part of an atom.
Bromine has five 4p electrons.
The same as its atomic number, with a positive sign: +9 for fluorine.
valence electron in nitrogen
It is dependent on the proton number (effective nuclear charge) and the number of electron shells (row number).
The electron(s) in the 1s sublevel will always experience the greatest force, because they are always the closest and the force increases as the distance decreases.
as you know we must first have the electron configuration to get the valence electrons. the electron configuration is: 1s2 2s2 2p6 3s2 3p6 4s2. we now have the electron configuration but we dont have the v.e. the last electron in the calcium atom are in the 4s orbital so that means that since it the only electron in the 4s orbital we will use it as a v.e. so as to get the v.e. we will subtract the shielding electrons from the nuclear charge shortly expressed by the formula below. Zeff=S-Z in this case Z will be the sum of the shielding electrons and s is the nuclear charge. Zeff=20-18 Zeff=2+ so the effective nuclear charge is 2+ or 2. hope you like it.
