Question 10

Question

Video Question #3 What do elements in the groups 1A through 8A have in common? (Choose all that apply)

a
they all will have the same oxidation states for the ions they form
b
they were all discovered around the same time
c
they all have similar properties
d
they all have the same number of valence electrons
e
they all have the same number of energy shells

select 3 that are CORRECT

Answer 1

The elements in groups 1A through 8A (the main group elements in the periodic table) have the following in common:

a. They all will have the same oxidation states for the ions they form. - This is generally true for elements within the same group, although the specific oxidation states can vary among the groups.

c. They all have similar properties. - Elements in the same group often exhibit similar chemical properties due to their similar valence electron configurations.

d. They all have the same number of valence electrons. - Each group (or family) of the periodic table has the same number of valence electrons, which chiefly determines the type of chemical reactions they participate in.

So, the three correct answers are: a, c, and d.
