Chemical Bonding

• Q: What is the general classification of elements?

  A: 1. Metals

  2. Non-metals

  3. Metalloids
• T or F: Metals are solid but weak conductors of electricity and heat

  A: F
• Q: Since metals are malleable and ductile, what are they made into?

  A: Malleable = sheets

  Ductile = wires
• Q: How many electrons do metals usually have and what do they do with them?

  A: 1 to 3, donate them
• Q: What are metals known to be due to their number of valence electrons?

  A: Cation
• T or F: Unexpectedly, nonmetals' elements have similar properties to those of metals

  A: F
• Q: What state/s of matter is/are nonmetals and how many valence electrons do they usually have?

  A: liquid and gas, 4 to 8
• T or F: Nonmetals are receivers of valence electrons to become stable

  A: T
• Q: What are nonmetals known to be?

  A: Anion
• Q: What can have properties of both metals and nonmetals?

  A: Metalloids
• Q: Which element type is usually the one giving because it only has a few valence electrons?

  A: Metals
• Q: Which element type is usually the one receiving because it almost has complete valence electrons?

  A: nonmetals
• Q: What will happen if elements donate, take, or share valence electrons?

  A: a bond is formed
• Q: What is a chemical bond?

  A: attractive force that holds atoms of elements together in a compound
• Q: What are the types of chemical bonding?

  A: 1. ionic bond

  2. covalent bond

  3. metallic bond
• Q: Describe what elements are involved in each bonding type?

  A: 1. Ionic - metal and nonmetal

  2. Covalent - two or more nonmetals

  3. Metallic - two or more metals
