electron cells

Question 1

WHERE ARE THE ELECTRONS?

Answer 1

The electrons of an atom are orbiting the nucleus in SHELLS.

Question 2

what energy store do electrons have

Answer 2

The electrons have an electrostatic energy store because they are near the nucleus.

Question 3

how many elecytons can each shell hold

Answer 3

Each shell can only hold a set amount of electrons before it becomes ‘FULL’.

1st Shell: Can hold 2 electrons.
2nd Shell: Can hold 8 electrons.
3rd Shell: Can hold 8 electrons.

REMEMBER: 2,8,8!

Question 4

HOW TO DRAW THE DIAGRAMS PROPERLY

Answer 4

As you add electrons to a shell, only draw them at the up, down, left and right positions:

If there are more than four electrons, you start to put them in pairs:
