Which has 2 electron in the 4s sublevel?
Ca
When comparing the energy of an electron in the 3d sub-level to that of an electron in the 4s sublevel of the same atom?
They are both capable of holding a maximum of 10
Is that 4s or 3d orbital to which an excited electron from 3p would first go?
An excited electron from the 3p orbital would most likely jump to the 4s orbital due to its lower energy level compared to the 3d orbital.
Why magnese show highest oxidation state in 3d series?
Manganese shows its highest oxidation state in the 3d series (+7) due to its small atomic radius, high effective nuclear charge, and the presence of empty 3d orbitals that can participate in bonding. This allows manganese to form strong covalent bonds and exhibit a wide range of oxidation states.
How do you write longhand for Ar4s23d?
To write the electron configuration for Ar (argon) with 4s^2 and 3d^1 in longhand, you first write the electron configuration for argon (Ar): 1s^2 2s^2 2p^6 3s^2 3p^6. Then, you add the additional electrons in the 4s and 3d orbitals: 4s^2 3d^1.
What will be the effective nuclear charge on 4s electron of zinc on the basis of Slater's rule?
The effective nuclear charge on the 4s electron of zinc, according to Slater's rule, would be lower than the actual nuclear charge due to shielding effects from inner electrons. It would be less than +30 (the nuclear charge of zinc) since the 3d electrons partially shield the 4s electron from the full charge of the nucleus.
What is the effective nuclear charge experienced by calcium's valence electrons?
The effective nuclear charge experienced by calcium's valence electrons is approximately +2, since calcium has 20 protons in its nucleus and 18 core electrons shielding the valence electrons from the full nuclear charge.
Even though zinc is after copper in the periodic table leading to an increase in the nulear charge by 1 which should therefore decrease the radius why is it larger than copper?
The electron configuration of zinc results in a filled d orbital, leading to increased electron-electron repulsions and a larger atomic radius compared to copper. This effect outweighs the increase in nuclear charge caused by the addition of one proton.
Is there nuclear energy in a iPhone 4S?
No.
Which has 2 electron in the 4s sublevel?
Ca
4S's of effective communication?
The 4S's of communication are Shortness,Simplicity,Strength,Sincerity.
When comparing the energy of an electron in the 3d sub-level to that of an electron in the 4s sublevel of the same atom?
They are both capable of holding a maximum of 10
What is the number of electrons in the in the outer shell of K plus?
K is potassium, and it is found in group I and period 4. It is an s block element. So, being in group I, this indicates it has ONE electron in the outer shell (4s).
Element with a 3- charge in the 4th energy?
An element with a 3- charge in the 4th energy would have a strong, stable nucleus with a strong nuclear force holding the protons and neutrons together. This element would also have a strong, repulsive electrostatic force between the protons in the nucleus and the electrons in the 4th energy level.
An element with 20 protons and 20 electrons gains one electron The electron goes into what type of orbital?
The extra electron would go into a 4s orbital because 4s can hold up to 2 electrons before 3d can be filled.
How many unpaired electrons does K have?
There is merely one unpaired electron in Potassium. The electron configuration of potassium is [Ar]4s^1. This means that potassium has all the electrons of argon, plus one more in the 4s orbital. All the electrons of argon are paired, so the one electron in the 4s orbital is the only unpaired electron.
Is that 4s or 3d orbital to which an excited electron from 3p would first go?
An excited electron from the 3p orbital would most likely jump to the 4s orbital due to its lower energy level compared to the 3d orbital.
