2- A single covalent bond contains 2 electron.
What are three characteristics of metallic bonds?
characteristics: Luster, ductile, heat conductors, and malleable
True or false and why?- Atoms form a covalent bond when they give up electrons.
False- Because atoms form a covalent bond when they share electrons.
What is involved in an ionic bond?
The complete transfer of electrons between atoms.
How does a covalent bond break?
Covalent bonds can be broken if energy is added to a molecule.
What is the main factor that affects the strength of a metallic bond?
Number of protons.
True or False and why?- Metalloids and inner transition metals form a metallic bond.

How are covalent bonds formed?
The sharing of electrons in the outer atomic orbital Form a covalent bond.
How are metallic bonds formed?
Metallic bonds are formed when many metal atoms share their pooled electrons.
True or False and why? - Bonds gain, lose, or share valence electrons to end up with 16 valence electron.
False- Because bonds gain, lose, or share valence electrons to end up with 8 valence electrons.
How are ionic bonds formed?
Ionic bonds form when there is a complete transfer of some electrons from one atom to another.
What are the three types of covalent bonds?
Single, Double, and Triple
What does a metallic bond consist of?
A metallic bond consists of closely packed atoms.
True or False and why?- When electrons are transferred between two atoms, a covalent bond is formed.
False- A covalent bond is formed when two atoms share electron pairs.
