Final answer:
The electronegativity of an atom is determined by the number of positive charges in the nucleus and the distance of outer electrons from the nucleus.
Step-by-step explanation:
Electronegativity of an Atom
Electronegativity is a measure of an atom's ability to attract electrons when it is part of a compound. The factors that determine electronegativity include:
- Number of positive charges in the nucleus: A higher number of positive charges in the nucleus increases electronegativity because the positive charges attract electrons more strongly.
- Distance of outer electrons from the nucleus: When the outer electrons are closer to the nucleus, the electronegativity increases because the attractive force between the electrons and the positive charges is stronger.
In summary, the number of positive charges in the nucleus and the distance of outer electrons from the nucleus are the main factors that determine the electronegativity of an atom.
