The Periodic Table

Question 1

In what order are elements arranged in the Periodic Table?

Answer 1

In order of increasing atomic number

Question 2

What are the periods?

Answer 2

The periods are the rows in order of increasing atomic number

Question 3

What are the groups?

Answer 3

There are 8 groups from Group 1 to Group 8 or 0. In each group the elements have similar properties

Question 4

Why do elements in the same group of the Periodic Table have similar chemical properties?

Answer 4

They have similar chemical properties because they all have the same number of electrons in their outer energy shell

Question 5

Why do the noble gases not readily react?

Answer 5

The noble gases do not readily react because they have full outer energy shells of electrons meaning they do not need to lose or gain any electrons. Noble gases are inert

Question 6

What does the period number represent?

Answer 6

The number of energy shells

Question 7

What does the group number represent?

Answer 7

The number of electrons in the outermost energy shell

Question 8

What does the atomic number represent?

Answer 8

The total number of electrons in all the energy shells

Question 9

What is an electronic configuration?

Answer 9

An electronic configuration is the way in which electrons are arranged in an atom
