The first ionization energy of gallium (Ga) is 578.8 kJ/mol. a. Give the chemical equation for the first ionization of Gallium. b. Is light with a wavelength of 285.5 nm able to ionize gallium

the correct answer is a

your answer is a. the enthalpy of formation for a pure element in its standard state is always positive.

what is the question here. i think you messed up.

each chemical family is represented as a group or column on the periodic table. based on chemical properties, there are 6 types of chemical families. group 1 represents alkali metals, group 2 represents alkaline earth metals, groups 3 to 12 represent transition metals, groups 13 to 16 represent non-metals and other metals, group 17 represents halogens and group 18 represents noble gases.
