Front

In a polar covalent bond, where do the electrons gather?

Back

Electrons gather around the atom with the Greatest Electronegativity.

Front

What is the goal of most elements in terms of valence electrons?

Back

Most elements aim to have 8 valence electrons.

Front

Define electronegativity.

Back

Electronegativity is the tendency of an atom to attract electrons in a chemical bond.

Front

What is a polar covalent bond?

Back

A polar covalent bond is a type of bond where electrons are shared unequally between two atoms.

Front

What is the significance of having 8 valence electrons?

Back

Having 8 valence electrons (octet rule) makes atoms more stable.

Front

How does electronegativity affect bond polarity?

Back

The difference in electronegativity between two atoms determines the polarity of the bond.

Front

What is the electronegativity value of Fluorine?

Back

Fluorine has the highest electronegativity value of 4.0.
