How many bonds does selenium make?
4 bonds.
Selenium has 4 valence electrons, which means it needs 4 more to have a full shell. It will make 4 bonds to get those full shells!

In a bond between calcium and fluorine, which element will accept the electrons in the bond?
Fluorine.
Since fluorine is more electronegative, it will accept the electron in a bond, turning into a negative ion.

Write how the electrons are distributed among each type of bond:
Metallic
Ionic
Polar Covalent
Nonpolar Covalent
Metallic- delocalized electrons, mobile electrons spread across the bonds of several neighboring atoms.
Ionic- electrons are transferred from one atom to another. The ions formed attract each other through electrostatic attractions.
Polar Covalent- electrons are shared unevenly. Uneven distribution of charge.
Nonpolar Covalent- Electrons are shared evenly.
