Calculate the energy change in kilojoules per mole when lithium atoms lose an electron to bromine atoms to form isolated Li + and Br − ions. [The E i for Li( g ) is 520 kJ/mol; the E e a forBr( g ) is -325 kJ/mol.] Will a lithium atom transfer an electron to a bromine atom to form isolated Li + ( g ) and Br − ( g ) ions? Explain.
