Ent will For each of the following atoms, write the electron configuration, referring to
the periodic table. Then write the formula of the ion the atom is most likely to
form and identify that ion as a cation or an anion. Finally, write the electron
configuration of the ion.
1. bromine (Br), element 35
2. gallium (Ga), element 31
3. sulfur (S), element 16
4. rubidium (Rb), element 37
Write the electron con

Astable electron arrangement for an atom is one that does not easily change. how is this arrangement arrived at? a. valence electrons are transferred or shared to create a full outer shell of electrons. b. valence electrons are discarded into space to create a full outer shell of electrons. c. protons (positive charge) pair with valence electrons (negative charge) to create a strong bond. d. outer shells with valence electrons are transferred or shared.
