Paper is a 3D object.
A piece of paper is 3D.
you go to google images and search for: "3d pokedex AR codes". there should be huge pictures full of AR codes. but do note that though you may have the AR codes you don't have the Pokemon on your pokedex
3D
Co2+ has 25 electrons with the configuration: [Ar] 4s2 3d5 no its [Ar]3d^7
usually black
In the d block, there are two notable exceptions to the standard electron configurations: chromium (Cr) and copper (Cu). Instead of the expected configurations of [Ar] 3d⁴ 4s² for chromium and [Ar] 3d⁹ 4s² for copper, their actual configurations are [Ar] 3d⁵ 4s¹ and [Ar] 3d¹⁰ 4s¹, respectively. These deviations occur to achieve greater stability through half-filled and fully filled d subshells.
I dont know where to buy them, but on sites like Serebii they show you the AR codes :)
Potassium: [Ar] 4s^1 Chromium: [Ar] 4s^1 3d^5 Copper: [Ar] 4s^1 3d^10
Yes you can draw the nets of 3D objects on graph paper
The ground state shorthand notation for iron (Fe) is [Ar] 3d^6 4s^2.
It is in 3D. Mario is the only one who makes the world 3D.
