Chemical Bonding

Why do atoms bond?

• They typically don't bond

• To add or take away energy levels

• To have a full valance shell.

• To have a full inner shell

Which bond does this picture best represent?

• Metallic bond

• ionic bond

• covalent bond

• James Bond

What do positive ions tend to do?

• lose electrons

• gain electrons

• lose protons

• gain protons

What happens when magnesium loses 2 electrons?

• It stabilizes to a net charge of 0

• It turns into an atom

• It becomes negatively charged

• It becomes positively charged

Ionic Bonding involves:

• The transfer of protons

• The transfer of neutrons

• The transfer of electrons

• None Of the above

Covalent compounds:

• Share electrons

• Transfer electrons

• Neither

What is a valence electron?

• an electron that is found in the outermost shell of an atom.

• an electron found in the innermost shell of an atom.

• an electron found in the middle shell.

What is the number of valence electrons for Neon and the other Noble Gases?

• 5

• 6

• 7

• 8

If an atom transfers an electron to another atom, those atoms form which bond?

• Ionic Bond, which is stronger than a covalent bonds

• Covalent Bond, which is stronger than ionic bonds

In chemical compounds, covalent bonds form when

• the electronegativity difference between two atoms is very large.
• electrons are completely transferred between two metals.
• pairs of electrons are shared between two nonmetal atoms.
• two nonmetal atoms are attracted to each other by opposite charges.
