Question

read the passage and answer the next two questions. 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. which other element is likely to show a similar chemical reaction with oxygen as shown by magnesium, and to which group does it belong? c, it belongs to group 1 ca, it belongs to group 2 k, it belongs to group 2 na, it belongs to group 1

Explanation:

Magnesium (\(Mg\)) is in Group 2 of the periodic table. Elements in the same group have similar chemical properties because they have the same number of valence electrons. Calcium (\(Ca\)) is also in Group 2. Carbon (\(C\)) is in Group 14, potassium (\(K\)) is in Group 1, and sodium (\(Na\)) is in Group 1. So, calcium is likely to show a similar chemical reaction with oxygen as magnesium.

Answer:

Ca, it belongs to Group 2
