Problem 1
What is the basic premise behind VSEPR?
Problem 1
Comment on the possible formation of the \(\mathrm{K}^{2+}\) ion. Why is its formation unlikely?
Problem 1
How many electrons will be in the valence shell of \(\mathrm{H}\) atoms when it makes a covalent bond?
Problem 1
Explain why the first two dots in a Lewis electron dot diagram are drawn on the same side of the atomic symbol.
Problem 1
Give an example of a nonpolar covalent bond. How do you know it is nonpolar?
Problem 1
Why can an odd-electron molecule not satisfy the octet rule?
Problem 2
What is the difference between electron group geometry and molecular geometry?
Problem 2
