Bohr Diagrams for Atoms/Ions

When elements form compounds, changes occur in the _____________ of
electrons. In some compounds, electrons are _____________ from one atom to
another, so that the atoms can have the stable electron arrangement of the
closest __________________.
As you can see in Figure 5 (and your drawing above), lithium has _____ electrons
in the first orbit and _____ electron in the second orbit. If lithium (a metal) LOSES the electron
in its outer orbit, it will look like this
but it is no longer neutral; it has formed an _____________ (a charged atom in
which the number of _____________ is different from the number of
_____________). The charge of lithium is _____, because it has 1 more proton than
electron.
When calcium forms a compound, from Figure 5 you can see that it has _____ electrons in the
outer shell. If it should lose these electrons, it will form an ion with a charge of ________
because it has 2 more _____________ than _____________.
