List the steps involved in russell-saunders (l-s) coupling to obtain states arising from an electronic configuration. write out the formulae involved and explain the meaning of any symbols used. (10) given that the lowest energy transition of atomic magnesium ([ne]3s? ) involves the promotion of an electron from the 3s atomic orbital to the 3p orbital: (1) obtain the states arising for both configurations, (ne]3s2 and [ne]3s3p. [10 m (ii) order the states derived in part (i) from the lowest to highest energy. (5 md (ii) from your answer in part (ii), determine the lowest energy allowed absorption transition of magnesium. justify your answer.

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.

if the temperature drops and becomes cool

then the atmosphere can be freezing as the water vapor in the air is at maximum (100%) and can be severely cold

also can be snowing lightly as the moisture in the air will start to solidify

and btw this is not chemistry but
