A) Electrons will be added to an atom starting from the lowest possible level or sublevel. B) Electrons will be added to an atom only if the orbitals are different colors.
C) Electrons will be added to an atom in a random order. D) Electrons will be added to an atom in a symmetrical manner.
 
Answer & Explanation Answer: A) Electrons will be added to an atom starting from the lowest possible level or sublevel.

Explanation:

Q:

Which of the following elements has the lowest electronegativity

A) Bromine B) Fluorine
C) Carbon D) Lithium
 
Answer & Explanation Answer: D) Lithium

Explanation:

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.
