Question

All elements in the same group A) have similar chemical properties. B) are not similar in any way. C) are in the same state at room temperature. D) have the same boiling and freezing points.

Answer 1

Answer:

Have similar chemical properties

Explanation:

• The periodic table of elements is made up of groups or families and periods.
• Elements in the same group or chemical family share similar chemical properties.
• For example, elements in group II have similar chemical properties. They include Calcium and magnesium.
• A similar chemical property of group II elements is that they react with water to form metal hydroxide and hydrogen gas.

Answer 2

Answer : The correct option is, (A) have similar chemical properties.

Explanation :

In a periodic table, the elements in horizontal rows known as periods and vertical columns known as groups.

In periodic table, elements having similar properties lies in the same vertical columns or groups because all the elements had same number of valence electrons.

or,

The elements have similar characteristics or similar chemical properties when they are belong to the same family or group this means that when they are placed in the same column of the periodic table.

Hence, the correct option is, (A) have similar chemical properties.
