3rd Periodic Trends Extra Credit Flashcard

Front

What is electronegativity?

Back

Electronegativity is a measure of the tendency of an atom to attract a bonding pair of electrons. It is a key factor in determining how atoms interact in chemical bonds.

Front

Which element has the lowest electronegativity in Period 3?

Back

Sodium (Na) has the lowest electronegativity in Period 3.

Front

Which element has a higher electronegativity: Fluorine (F) or Sodium (Na)?

Back

Fluorine (F) has a higher electronegativity than Sodium (Na).

Front

What is atomic radius?

Back

Atomic radius is the distance from the nucleus of an atom to the outermost shell of electrons. It is an important factor in determining the size of an atom.

Front

Which element has the smallest atomic radius?

Back

Helium has the smallest atomic radius among the noble gases.

Front

Which element has a smaller atomic radius than Zinc?

Back

Copper has a smaller atomic radius than Zinc.

Front

Which element has a higher electronegativity: Oxygen (O) or Chlorine (Cl)?

Back

Oxygen (O) has a higher electronegativity than Chlorine (Cl).

Front

What trend does electronegativity follow across a period?

Back

Electronegativity generally increases across a period from left to right due to increasing nuclear charge.

Front

What trend does atomic radius follow down a group?

Back

Atomic radius generally increases down a group due to the addition of electron shells.

Front

What is the significance of electronegativity in chemical bonding?

Back

Electronegativity differences between atoms determine the type of bond (ionic, covalent, or polar covalent) that will form.
