Which element has the electron configuration AR 3d104s2?
Arsenic
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.
How many 3d electrons are in AR?
It is non-reactive because the shells are full. Argon has three electron shells. The third shell is filled with eight electrons. That is why it does not easily combine with other elements.
What is the electron configuration called that has 18 electrons?
The resulting configuration above, with 18 electrons in the outermost principal energy level, is referred to as a pseudo noble-gas electron configuration .
What is the electronic structure of an argon atom 40 18 Ar?
Argon Atomic and Orbital Properties Argon atoms have 18 electrons and the electronic shell structure is [2, 8, 8] with Atomic Term Symbol (Quantum Numbers) 1S0.

What element is AR 3d5?
The electron configuration for, say, iron indicates an argon electronic core (see argon) plus six 3d electrons and two 4s electrons. Ground Ionization Electron configuration state energy Element (3d5 = five 3d electrons, etc.)
Where can I find the electron configuration of an element?
The electron configuration states where electrons are likely to be in an atom. If you don’t have a chart, you can still find the electron configuration. Use the element blocks of the periodic table to find the highest electron orbital.
Where does argon rank on the periodic table?
Argon is a chemical element with the symbol Ar and atomic number 18. It is in group 18 of the periodic table and is a noble gas. Argon is the third-most abundant gas in the Earth’s atmosphere, at 0.934% (9340 ppmv).
Why are electron configurations in noble gas shorthand?
To save room, the configurations are in noble gas shorthand. This means part of the electron configuration has been replaced with the element symbol of the noble gas symbol. Look up the electronic configuration of that noble gas and include that value before the rest of the configuration.
