An element’s atomic number tells you the number of ________ in the nucleus. The number of________ in an atom is equal to the number of _________. How many electrons are there in the elements listed above:
2) ) ) ) )
In the first shell of an atom there are _____ electrons. In the second shell there are ___ electrons. In the third shell there are ___ electrons.
Draw the electrons and their shells onto the atoms below:
In a metal, the ________ in the ________ shell are able to move. This is the reason why metals are very good at _____________ h____ and __________.
The more __________ in the outer shell, the better the metal is at _____________.
In lithium each atom has ____ electron in it’s outer shell. This means that for each atom in a lump of lithium there is one free electron that is able to move around.
