Electronegativity (As)

Define electronegativity.

• The ability of an electron to attract atom to itself.

• The ability of a molecule to attract electrons to itself.

• The ability of an atom to attract electrons to itself.

• The ability of an ion to attract electrons to itself.

Fill in the blank with the correct trend:

The trend of electronegativity ________ across the period and _________down the group?

• increases... increases

• decreases... decreases

• decreases... increases

• increases... decreases

Electronegativity trends are the same as:

• Atomic radius trends

• Ionization energy trends

• Both of these

• None of these

Which of the following ordered pairs of elements has the highest difference in electronegativity?

• Li and Be

• Li and F

• O and F

• F and F

Put these in increasing order of electronegativity:
F, N, B

• B < N < F
• B < F < N
• N < F < B
• F < N < B

Which of the following correctly identifies which has the higher electronegativity, Sn or Te, and supplies the best justification?

• Sn, because of its higher nuclear charge

• Sn, because of the closer distance between nucleus and bonded electrons

• Te, because of its higher nuclear charge

• Te, because of the closer distance between nucleus and bonded electrons

Based on the data in the table above, which of the following correctly predicts the relative electronegativity of the elements X, Y, and Z, and provides the correct reason?

• X > Y > Z because smaller elements have a stronger nuclear attraction with valence electrons

• X > Y > Z because smaller elements have a weaker nuclear attraction with the valence electrons

• Z > Y > Z because larger elements have a stronger nuclear attraction with valence electrons

• Z > Y > Z because larger elements have a stronger nuclear attraction with the valence electrons

Based on periodic trends and the data in the table above, which of the following are the most probable values of ionization energy and electronegativity for rubidium?

• 403 kJ/mol, 1.22 D

• 403 kJ/mol, 0.82 D

• 600 kJ/mol, 0.82 D

• 600 kJ/mol, 1.22 D

A compound is more likely to be (a)   if the difference in electronegativity is low.

A greater difference in electronegativity between two atoms will result in sharing of electrons hence forming ionic bond

• TRUE

• FALSE
