Ionic, Covalent, and Metallic Bonds

Why do elements bond with other elements?

How many electrons does an atom need to create a stable electron configuration?

• 10
• 4
• 6
• 8 (or 2 for hydrogen and helium)

Why would a metal rather give away electrons than receive them like the non-metal does?

• Metals are in groups 1,2,13 and they will give away to reach their full shell underneath

• It doesn't want them

What is the difference between an anion and cation?

• An anion is positively charged, while a cation is negatively charged.
• Both anions and cations are neutral particles.
• An anion is a type of molecule, while a cation is an atom.
• An anion is negatively charged, while a cation is positively charged.

When at atom gives up electrons does it become an anion or cation?

• cation
• isotope
• neutral atom
• anion

How is a covalent bond different from an ionic bond?

All covalent bonds are about sharing electrons. How is the sharing different polar and nonpolar bonds?

• Polar bonds are formed only between metals, while nonpolar bonds are formed between nonmetals.
• Polar bonds involve unequal sharing of electrons, while nonpolar bonds involve equal sharing.
• Both polar and nonpolar bonds involve unequal sharing of electrons.
• Polar bonds involve no sharing of electrons, while nonpolar bonds involve complete sharing.
