Lesson 9 Chemical Bonds: Ionic

What are valence electrons responsible for?

• Determining the atomic number

• Bonding with other atoms

• Determining the color of the element

• Creating chemical reactions

What is the octet rule?

• A rule for predicting the crystal arrangement of ions

• A rule that states how atoms achieve the electron stability of a noble gas

• A rule for determining the charge of an ion

• A rule for naming ionic compounds

What is the consequence of a process of electron transfer between atoms?

• Covalent bond

• Polar bond

• Ionic bond

• Metallic bond

What type of compounds are formed when cations and anions join?

• Metallic compounds

• Polar compounds

• Ionic compounds

• Covalent compounds

What is the type of solid that ionic compounds are?

• Amorphous solid

• Crystal Solid

What do oxidation numbers represent?

• The number of protons in the nucleus

• The atomic mass of the element

• The number of neutrons in the nucleus

• The charge of the ion

What is the oxidation number for nonmetals in group 7A?

• -2

• +1

• -1

• -3

How are cations named?

• Add the suffix -ide

• Change the name completely

• Keep the name of the element

• Add the prefix di-

What is the lowest whole-number ratio of ions in an ionic compound called?

• Molecular formula

• Empirical formula

• Structural formula

• Formula unit

How do nonmetals react in an electron transference?

• Gain the electrons needed to complete the octet

• Donate their valence electrons

• Accept the electrons needed to complete the octet

• Lose their valence electrons
