Which element has the electron configuration AR 4s2 3d8?
1 Expert Answer The nobel gas that comes before Ni in the periodic table is Argon which has 18 electrons. So we use Ar electron configuration and add 10 more electrons. Since Ni is a petiod 4 transition metal, it will have 3d valence electrons. So, the abbreviated configuration for Ni is [Ar] 4s2 3d8.
Which element has the electron configuration AR 4s2 3d10 4p4?
selenium element
The obtained atomic number 34 corresponds to the selenium element. Hence, the neutral element that has the electron configuration of [Ar]4s23d104p4 [ A r ] 4 s 2 3 d 10 4 p 4 is Selenium.
What is the atomic number of the element with the electron configuration AR 4s23d10?
The element with an electronic configuration of (Ar)4s23d104p3 ( A r ) 4 s 2 3 d 10 4 p 3 is Arsenic. This is because Ar represents 18 atoms, 2 atoms are in 4s2 4 s 2 , a0 atoms in 3d10, and 3 atoms in 4p^3. All the atoms are (18 + 2 + 10 +3) =33. The element with atomic number 33 in the periodic table is Arsenic.

What element is 1s2 2s2 2p6 3s2 3p6 4s2 3d7?
Copper
The electron configuration for Copper (Co) is: 1s2 2s2 2p6 3s3 3p6 4s2 3d7. A chemist would shorten this notation to just “3d7” – calling Copper by the subshell of highest energy that contains any electrons.

So, an antimony atom with charge +2 has an electron configuration of 1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p6 5s2 4d10 5p1.
What element is AR 4s 23d 104p 4?
That is, however, a noble gas shorthand for the electron configuration of selenium. Notice how the number of electrons corresponds to the number of protons in a neutral element.
What is KR 5s24d105p3?
What is KR 5s24d105p3? Antimony. [Kr] 5s2 4d10 5p3.
What is the electron configuration of an atom?
Electron configuration is the arrangement of electrons around the nucleus of an atom based on their energy level.
Which is more diffuse the 4s orbital or the 3d orbital?
ANSWER: It is more accurate to consider the relative energies of electronic configurations than of atomic orbitals. In other words, the energies of the electronic configurations ultimately dictate the apparent ordering of the atomic orbital energies. The 4s orbital is more diffuse that the 3d orbital.
How are electrons arranged in a Fe3 + ion?
For the Fe3+ ion we remove a total of three electrons (two from the 4s2 and one form the 3d6) leaving us with 1s 2 2s 2 2p 6 3s 2 3p 6 3d 5 1s2 2s2 2p6 3s2 3p6 3d5 The configuration notation provides an easy way for scientists to write and communicate how electrons are arranged around the nucleus of an atom.
How to determine the electron configuration of an arsenic atom?
In a neutral atom, the number of electrons equals the number of protons, which means that neutral arsenic atoms have 33 electrons. By using the Aufbau diagram (shown below) we can determine the full electron configuration for a neutral arsenic atom. #”1s”^2″2s”^2″2p”^6″3s”^2″3p”^6″3d”^(10)”4s”^2″4p”^3#.
