The diagram shows an electron shell model of a sodium
atom
how would the model change as the atom forms bonds?
639 00
the third shell would have eight electrons after the atom
gains seven electrons to fill the outermost shell.
the third shell would be empty so that the eight
electrons in the second level would be outermost after
the atom loses one electron
the first and third shells would be empty so that the
atom would have eight electrons in its remaining shell
after the atom loses three electrons.
the first shell would have two electrons and the second
shell would have six electrons after the atom loses three
electrons
