Electronic Structure ATOMS, BONDING AND MOLES

Question 1

What is the electronic configuration for the first 20 elements?

Answer 1

2,8,8,10

Question 2

What does the group tell you about the atom’s electronic structure?

Answer 2

All the elements in the same group will have the same number of electrons in their atoms highest energy level. Therefore, all elements in group 1 will have 1 electron in their highest energy level.

Question 3

What does the electronic structure mean about it’s reactivity?

Answer 3

If the elements outer shell is full it is unreactive. Therefore, all elements in group 8 (the noble gases) do not react. They have a full outer shell.
