Question

1. what does mendeleevs periodic law state? a. properties of elements are periodic functions of their atomic masses b. properties of elements repeat every 4th element c. elements are arranged in increasing density d. every element reacts with oxygen 7. which law inspired the modern periodic table? a. law of gravity b. law of octaves c. mendeleevs periodic law d. law of conservation of mass 8. which group contains elements with similar chemical properties? a. groups/families b. rows c. periods d. blocks 9. newlands compared the periodic pattern of elements to: a. a musical scale b. a mathematical equation c. a planetary orbit d. a book index

Explanation:

• For question 6: Mendeleev's periodic law states that the properties of elements are periodic functions of their atomic masses.
• For question 7: Mendeleev's Periodic Law inspired the modern periodic table.
• For question 8: Groups/Families contain elements with similar chemical properties.
• For question 9: Newlands compared the periodic pattern of elements to a musical scale.

Answer:

1. A. Properties of elements are periodic functions of their atomic masses
2. C. Mendeleev's Periodic Law
3. A. Groups/Families
