Search: lewis structure

Number of results: 3,722

I have been able to draw a few very simple Lewis structures but most cannot be drawn because of the way the boards handles spaces (it recognizes only the first space and ignores the other ones). Here is a site that will give that.

Update on what's going on in my head: I think I'm getting confused because I am thinking of a bronsted acid/base instead of lewis. The weaker the lewis base is, the stronger the lewis acid is. So once the lewis base donates its electrons, the halogen of the lewis acid falls ...

I don't think so. Drawing the Lewis structure DOES show that they have a pair of electronic but to be a Lewis acid the molecule under question (O3, H2Se, AsH3) must accept a pair of electrons so the O3, AsH3, and H2Se are not donating anything. You want to know if they have s...

The Lewis electron dot structure for SF4 has 10 electrons around the central atom; i.e., that's 4 pairs of electrons for each F atom (8 electrons total) + 2 unpaired electrons for a total of 10. That makes it an AX4U type structure (see-saw). Try sp3d hybridization.

You must write a Lewis structure that obeys the Octet Rule. You start by counting the number of valence electrons on the two central atoms, N(5), O(6), and the three H's (1 each). Electrons must be shared so that N and O end up with 8 electrons around them (shared and unshared...
