Electronegativity is the tendency for an atom to attract electrons. There are general trends on the periodic table which you can use to determine the relative electronegativity for different elements, but otherwise you can also look at their valence shell and effective nuclear charge to determine their relative electronegativity.

Here from the given options, Lithium has least tendency to attract electrons and thus has a lower electronegativity.

Shinjuku Station in Tokyo, Japan, has an average of 3.64 million passengers pass through it each day. It has more than 200 exits.

The card was established by Frank McNamara and Ralph Schneider.

From the given data, 

if 60% = 45 minutes
