question : what is the two dimensional coordination number of a molecule in square close packed layer ?
Here we gonna discuss here the question what is the two dimensional coordination number of a molecule in square close packed layer asked by one of our student online.
Key point remember to answer this question : first of all you have to learn what is coordination number , the coordination number is the number of nearest neighbour particles by which the solid or lattice is made up. let us suppose one particle has 4 nearest neighbour particles , it means 4 other particles are present there then the coordination number will be 4. and also given that square close packing is given in 2 dimension.
solution : two dimensional coordination number of a molecule in square close packed layer can be draw as follows –
Now find the nearest neighbour particles of centre particle , we can see that there are 4 atoms which are present to surround the center atom , it means the atom which can touch the centre atom are four , hence the coordination number for given figure is 4 (four) , that is our correct answer as per question requirement.
