In chemical bonding, the distribution of electrical charge over the atoms joined by the bond.

• Polarity

• Electronegativity

• Polar covalent bond

- covalent bond in which the bonding electrons are shared equally between the two atoms.

• Polar covalent bond

• Non-polar covalent bond

• Electronegativity

Answer explanation

- when atoms with different electronegativities share electrons in a covalent bond

• Polar covalent bond

• Non-polar covalent bond

• Electronegativity

Answer explanation

The ability of an atom in a molecule to attract shared electrons is indicated by the property is called:

• Polarity

• Electronegativity

• Non-polar covalent bond

Whithin a GROUP, electronegativity values increase from left to right.

Whithin a PERIOD, electronegativity values decrease from top to bottom.

• TRUE

• FALSE

Answer explanation

Whithin a GROUP (PERIOD), electronegativity values increase from left to right.

Whithin a PERIOD(GROUP), electronegativity values decrease from top to bottom.

Which this are true about Cl2?

• It has a polar bonds thus, Cl2 is a nonpolar molecule.

• It has a polar bonds thus, Cl2 is a nonpolar molecule.

• It has polar bonds thus, Cl2 is a polar molecule.

The presence of polar covalent bonds in a molecule is not an indication that the molecule is a polar as a whole.

• TRUE

• FALSE

This is the measure of how quickly the reactants in a reaction change into the products of the reaction.

• Reaction rate

• Reactants

• Product
