Question

read the passage and use the diagram to answer the next question. during a classroom experiment, a burning magnesium ribbon was dropped into a glass test tube filled with oxygen. a bright white flame was produced. a white powdery substance formed at the end of the reaction. 6. which other element is likely to show a similar chemical reaction with oxygen as shown by magnesium, and to which group does it belong? a. ca, it belongs to group 2 b. na, it belongs to group 1 c. k, it belongs to group 2 d. c, it belongs to group 1

Explanation:

Elements in the same group of the periodic table have similar chemical properties. Magnesium (\(Mg\)) is in Group 2. Calcium (\(Ca\)) is also in Group 2. Sodium (\(Na\)) and potassium (\(K\)) are in Group 1. Carbon (\(C\)) is in Group 14. Since \(Ca\) is in the same group as \(Mg\) (Group 2), it is likely to show a similar chemical reaction with oxygen.

Answer:

A. Ca, it belongs to Group 2
