What is effective nuclear charge of beryllium?
1.5
In going down a group in the periodic table what effect does electron shielding generally have on the effective nuclear charge acting on the outermost electron in an atom?
Electron shielding decreases the effective nuclear charge.
What is the effective nuclear charge of an atom primarily affected by?
inner electrons
What is the approximate effective nuclear charge for a valence electron in krypton?
2
Does the sun have oxygen to support combustion?
No. The sun is about 1% oxygen but it does not carry out combustion. It is instead powered by nuclear fusion.
Is nuclear energy effective?
Yes, nuclear fission reactors are very effective and can generate a lot of power. That is why nuclear fission reactors are very effecive
Why is the first ionisation energy of hydrogen and oxygen the same?
The outer valence electron lies in a 1s orbital in Hydrogen. The effective nuclear charge of hydrogen can be taken as Z = 1. The electron that is being ionised in Oxygen lies in a 2p orbital which has an effective nuclear charge of Z = 8-(3.4 or 4.5 or something). The point is, this nuclear charge at a greater distance from the nucleus means the energies of the electrons are similar and so ionisation energis required are too similar.
Are nuclear weapons effective?
Yes they are very effective. Nuclear weapons are dangerous and really effective to destroy all life on earth. They are very powerful.
Which activity is effective for increasing oxygen production?
Replanting trees is effective for increasing oxygen production.
What is the effective nuclear charge for the atom Mg?
the effective nuclear charge on barium is 2.
What is effective nuclear charge of beryllium?
1.5
How effective was the policy of nuclear deterrence in light of the number of nuclear weapons available?
osama
Does nuclear fusion convert oxygen to hydrogen?
No. Nuclear fusion will convert hydrogen to helium and, at higher temperatures, oxygen into silicon, phosphorus, and sulfur.
The universal force that is most effective over the longest distances is?
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.
What do mean by effective nuclear charge?
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
Which is the main issue that limits the degree that nuclear power is used for energy?
the effective storage and disposal of nuclear waste
In going down a group in the periodic table what effect does electron shielding generally have on the effective nuclear charge acting on the outermost electron in an atom?
Electron shielding decreases the effective nuclear charge.
