What can you infer about elements that are in the same group? a. they will have the same atomic mass b. they will display similar chemical and physical properties c. they will contain the same number of protons d. they will emit x rays of similar frequency

b.They will display similar chemical and physical properties.

Step-by-step explanation:

We have to find about the elements that are in the same group.

In modern periodic table

Elements are arranged in group according to similar properties.

The elements which have same properties are placed in the same group and mass of different elements are different in the group.

The outer electronic configuration of every element in the same group are same.

Therefore, the physical and chemical properties of the elements are same in the group.

Hence, option B is true.

b.They will display similar chemical and physical properties.

22 and 22

step-by-step explanation:

10 plus 12 equals 22.

12 plus 10 also equals 22 because regardless of what order they're in, they're gonna equal the same thing.
