I NEED HELP!!!!
Which group contains elements that are most likely to have similar properties?

Alithium, beryllium, and boron
Bnitrogen, arsenic, and antimony
Cpotassium, calcium, and gallium
Dcesium, platinum, and radon

Verified Answer :

the answer would be B. Because elements in the same group have similar properties.

Answer: The correct answer is option B.

Explanation:

Elements which lie in the same group most likely have similar chemical properties.

From the given options:

Option 1: Lithium, beryllium and boron.

Lithium lies in Group 1, Beryllium in group 2 and boron in Group 13. As, these elements do not lie in the same group and hence, the properties of these elements will not be the same.

Option 2: Nitrogen, arsenic and antimony

All these elements lie in Group 15 of the periodic table and hence will have the same properties.

Option 3: Potassium, calcium and Gallium

Potassium lies in Group 1, Calcium in group 2 and Gallium in Group 13. As, these elements do not lie in the same group and hence, the properties of these elements will not be the same.

Option 4: Cesium, Platinum and Radon.

Cesium lies in Group 1, Platinum in group 10 and Radon in Group 18. As, these elements do not lie in the same group and hence, the properties of these elements will not be the same.

Therefore, the correct option is Option B.
