Consider the following elements with their period number and valence electrons. {:("Elements","Period number","Total valence"e^(-)),(P,2,4),(Q,2,6),(R,3,7),(S,3,3),(T,3,6),(U,3,4):} According to the given informations, answer the following questions : Choose the correct statement :

Answer»

Q has maximum value of electron affinity
R has maximum value of ELECTRONEGATIVITY
S has maximum ATOMIC size
T and U are same GROUP elements

Solution :Maximum electron affinity is of R. `"" ` Maximum electronegativity is of Q
T and U belong to DIFFERENT GROUPS.
