multiple - choice question
what is electronegativity?
how much energy it takes for an atom to lose an electron.
the ability of an atom to attract a shared pair of electrons.

multiple - choice question
in a lewis dot structure, what is represented by dots
neutrons
valence electrons
protons
all electrons

Explanation:

Electronegativity is defined as the ability of an atom to attract a shared - pair of electrons. In a Lewis dot structure, dots represent valence electrons. Neutrons are not represented in Lewis dot structures, photons are not related to Lewis dot structures in this context, and it is not all electrons (just valence electrons) that are represented by dots.

Answer:

• For "What is electronegativity?": The ability of an atom to attract a shared pair of electrons.
• For "In a Lewis dot structure, what is represented by dots?": Valence Electrons
