Nitrogen is the central atom:     There are 5 + 3×6 + 1 = 24 electrons, and 6 are used to make the two covalent bonds. The oxygens get 6 electrons as three lone pairs:       One … Read more

B is the central atom, so we can draw a preliminary skeletal structure:     There is a total of 3 + 4×7 + 1 = 32 electrons, and 8 are used to make the covalent bonds. Halogens on terminal … Read more

Nitrogen is the central atom:     There are 5 + 2×6 + 1 = 18 electrons, and 4 are used to make the two covalent bonds. Both oxygens get 6 electrons as three lone pairs, and nitrogen gets one … Read more

Sulfur is the central atom:     There are 3×6 + 6 + 2 = 26 electrons, and 6 of them are used to make 3 bonds. Three oxygens take 3 lone pairs each and one goes to the sulfur: … Read more

Phosphorous is the central and there are 5 + 4×6 + 3 = 32 electrons. Give each oxygen three lone pairs:     All the electrons are used and the only thing to fix is the ionic charge. As drawn, … Read more

Sulfur is the central atom:     There are 4×6 + 6 + 2 = 32 electrons, and 8 of them are used to make 4 bonds. The four oxygens take 3 lone pairs each and no electrons are left: … Read more

There are 4 + 3×6 + 2 = 24 electrons. The carbon goes in the middle, and the oxygens take 6 electrons each as three lone pairs:     The carbon lacks an octet, so we use a lone pair … Read more

Carbon is the central atom:     There are 6 + 4 + 5 + 1 = 16 electrons, and 4 are already taken to make two covalent bonds. The remaining 12 are divided between the S and N as … Read more
