Had a lot of excersises to do for Chem and these were ones I was unsure on. Thanks

The NCO bond angle is formamide, H2NCHO, is

Atoms of period 3 and beyond can undergo sp3d2 hybridization, but atoms of period 2 cannot.

Fifth row transition metals lose the electrons in the 5s orbital before losing 4d electrons.

The charge on monatomic main group anions is equal to group number minus 8.

According to valence bond theory, overlap of bonding orbitals of atoms will weaken a bond, due to electron-electron repulsion.

If n=1, then 1 can only equal 1.

What is the total number of lone pairs in formamide, NH2CHO?

Hydrogen will make only 1 bond and have no long pairs in a vast majority of Lewis Structures.
