A central atom bonded to 6 negative regions with 2 pairs of lone pairs is called...?
sea-saw
square planar
square pyramid
Which of these apply to drawing lewis structures?
Count total number of valence electrons.
Underline the central atom
The atom that is the "most electron needy," ( the one which is further right on the periodic table) is placed in the middle.
Link other atoms to the central atom using single covalent bond (- =2e).
All the atoms must contain 8 electrons except Be=4 , B=6 and H=2
If an atom has insufficient electrons, take a lone pair from a neighbour and create multiple bonds between them.
Which of these have a polar bond.
H-H
H-F
What makes a molecule polar?
Same atoms bonded together
Different atoms bonded together
3D symmetrical molecule
3D asymmetrical molecule
The shape of the PCl3 molecule is trigonal pyramid.
