1.41 Describe the limitations of particular representations and models, Flashcards
1
Q
What is a main limitation of dot and cross, ball and stick models?
A
They apply well only to a small class of solids composed of Group 1 and 2 elements with highly electronegative elements such as the halogens.
2
Q
What do dot-cross diagrams fail to express in covalent molecules?
A
They do not express the relative attraction of shared electrons due to electronegativity.
3
Q
What is a limitation of 2D diagrams?
A
They do not show the 3D arrangement of atoms.
4
