Answer:
A solid's particles fit closely together. The forces between the particles are so strong that the particles can not move freely; they can only vibrate. This causes a solid to be a stable, non-compressible shape with a definite volume.
Explanation:
I honestly don't know if that's right...
Slow cooling of magma results in the formation of c. coarse-grained textured rocks. An example of a coarse grained textured rock formed in this fashion is granite. As the rate of cooling of igneous rocks increases, the size of the crystal that is formed decreases. The Bowen's reaction series shows the different rocks cooled at different rates.
Answer:
expected configuration for Cr is
1s2 2s2 2p6 3s2 3p6 4s2 3d4
but in real, it is
1s2 2s2 2p6 3s2 3p6 4s1 3d5
electron from 4s orbital jumps to 3d orbital to get stable configuration.
so the last electron comes in 3d orbital as filling of 3d takes place after filling of 4s orbital.
Hence,quantum numbers for last electron in Cr is :-
n = 3
l = 2
m = +2
s = +1/2
