Bonds
When atoms share electrons, they form a chemical bond, or covalent bond.
no. they will form covalent bond
A chemical bond
Covalent bonds share electrons.
Br2, bromine has a single covalent bond
Yes, they form a polar covalent bond e.g. in NF3
covalent bond
Covalent bond by sharing
Hydrogen can form a covalent bond with nitrogen to create ammonia (NH3).
No, oxygen and nitrogen do not form an ionic bond. They are both nonmetals and tend to form covalent bonds where they share electrons rather than transfer them.
Every halogen can form their molecules by a single covalent bond.
The bond between F and Cl is a polar covalent bond. Fluorine is very electronegative and Cl is not as much. The difference is large enough to be considered polar.
