The correct answers from the choices provided are:
b. they all have similar properties - This is true as elements in the same group (1A to 8A) exhibit similar chemical properties due to their similar electron configurations.
d. they all will have the same oxidation states for the ions they form - This is generally true for elements within the same group, as they tend to form ions with similar charges.
e. they all have the same number of valence electrons - This is true, as elements in the same group have the same number of valence electrons, which influences their chemical behavior.
So the three correct answers are **b, d, and e**.
Option **a** is incorrect because elements in different groups may have different numbers of energy shells. Option **c** is also incorrect, as elements in these groups were discovered at different times throughout history.
b. they all have similar properties - This is true as elements in the same group (1A to 8A) exhibit similar chemical properties due to their similar electron configurations.
d. they all will have the same oxidation states for the ions they form - This is generally true for elements within the same group, as they tend to form ions with similar charges.
e. they all have the same number of valence electrons - This is true, as elements in the same group have the same number of valence electrons, which influences their chemical behavior.
So the three correct answers are **b, d, and e**.
Option **a** is incorrect because elements in different groups may have different numbers of energy shells. Option **c** is also incorrect, as elements in these groups were discovered at different times throughout history.
