RegChemistry S2-Final Flashcard

Front

What is electronegativity?

Back

Electronegativity is a measure of the tendency of an atom to attract a bonding pair of electrons.

Front

Which family of elements is the least electronegative?

Back

Alkali metals are the least electronegative family of elements.

Front

What is the trend of atomic radius in the periodic table?

Back

Atomic radius tends to decrease across a period and increase down a group.

Front

What is the formula for ammonium phosphate?

Back

The formula for ammonium phosphate is (NH₄)₃PO₄.

Front

True or False: Ionization energy generally decreases as you move down a group in the periodic table.

Back

True.

Front

What happens to ionization energy as you move across a period?

Back

Ionization energy generally increases as you move across a period.

Front

What is the largest ion between I and I⁻?

Back

I⁻ (iodide ion) has a larger radius than I (iodine atom).

Front

Define atomic radius.

Back

Atomic radius is the distance from the nucleus of an atom to the outermost shell of electrons.

Front

What is the trend of ionization energy down a group?

Back

Ionization energy generally decreases down a group.

Front

What is the significance of noble gases in terms of electronegativity?

Back

Noble gases have a complete valence shell and are generally considered to have no electronegativity.
