Determine whether each compound is ionic or covalent and write the appropriate Lewis structure.
(b) CHFO (carbon is central)
- Ionic bonds are formed between atoms when electrons are transferred from one atom to another. Ionic bond is a bond between nonmetals and metals .
- Covalent bonds are formed between atoms when pairs of electrons are shared between atoms. A covalent bond is between two nonmetals.
Lewis structure :
It is the ionic compound .
Potassium loses one valence electron getting charge of -1 and get paired with sulphur which is having 2 unpaired electrons forming the negative charge that is -2.
b) CHFO (carbon is central)
It has a covalent bond First, Carbon (C)your least electronegative atom goes in the center and is surrounded by Hydrogen H), Oxygen (O), and Fluorine (F). Then, create a single bond between the Hydrogen (H) and the central atom, Carbon (C). Next, create a single bond between Carbon (C) and Fluorine (F); then, draw three electron pairs around Fluorine (F). Next, create a double bond between Carbon (C) and Oxygen (O). Then,around Oxygen (O), place two electron pairs.
For the PBr3 Lewis structure we first count the valence electrons for the PBr3 molecule using the periodic table. Once we know how many valence electrons there are in PBr3 we can distribute them around the central atom and attempt to fill the outer shells of each atom.
