Bonding Review

Covalent bonds are between...

• Metal and Non-metal
• Non-metal and Non-metal
• Metal and Metal

Ionic bonds are between...

• Metal and Non-metal
• Non-metal and Non-metal
• Metal and Metal

How are covalent bonds formed?

• Sharing of electrons
• Transfer of electrons

How are ionic bonds formed?

• Transfer of electrons
• Sharing of electrons

A single covalent bond involves the sharing of

• only one electron.

• two electrons.

• three electrons.

• a variable number of electrons, which depends on the bonding atoms.

Atoms that are bonded with an electronegativity difference of 0 to 0.3 are generally considered to be

• negatively charged compounds.

• nonpolar-covalent compounds.

• polar-covalent compounds.

• ionic compounds.

Atoms seldom exist as in independent particles in nature because

• as single particles, most atoms have low potential energy.

• their electronegativity is much lower when they combine with other atoms.

• atoms are more stable when they combine with other atoms.

• neutral particles are rare.

The mutual electrical attraction between nuclei and electrons of two different atoms is called a

• chemical bond

• nuclear bond

• intermolecular force

• structural formula

Nonmetals tend to 

• gain electrons and become positive

• lose electrons and become positive

• gain electrons and become negative

• lose electrons and become negative

Metals tend to 

• gain electrons and become positive

• lose electrons and become positive

• gain electrons and become negative

• lose electrons and become negative
