Exploring Atomic Properties and Trends

What is the trend in atomic size as you move down a group in the periodic table?

• Atomic size remains constant as you move down a group in the periodic table.

• Atomic size decreases as you move down a group in the periodic table.

• Atomic size fluctuates randomly as you move down a group in the periodic table.

• Atomic size increases as you move down a group in the periodic table.

How does the atomic size change across a period from left to right?

• Atomic size decreases across a period from left to right.

• Atomic size increases across a period from left to right.

• Atomic size remains constant across a period from left to right.

• Atomic size fluctuates randomly across a period from left to right.

What factors influence the ionization energy of an element?

• Temperature, pressure, and volume.

• Atomic size, nuclear charge, electron shielding, and electron configuration.

• Color, texture, and density.

• Atomic weight, molecular mass, and boiling point.

Why does ionization energy generally increase across a period?

• Ionization energy is unaffected by atomic size.

• Ionization energy generally increases across a period due to increasing nuclear charge.

• Ionization energy remains constant across a period.

• Ionization energy decreases due to increased electron shielding.

What is the relationship between atomic size and ionization energy?

• Ionization energy has no relation to atomic size; they are independent properties.

• As atomic size decreases, ionization energy remains constant.

• Atomic size and ionization energy are inversely related; as atomic size increases, ionization energy decreases.

• Atomic size and ionization energy are directly related; as atomic size increases, ionization energy increases.

How does metallic character change as you move from left to right across a period?

• Metallic character increases from left to right across a period.

• Metallic character remains constant across a period.

• Metallic character decreases from left to right across a period.

• Metallic character fluctuates randomly across a period.

What is the trend in metallic character as you move down a group?

• Metallic character remains constant as you move down a group.

• Metallic character increases as you move down a group.

• Metallic character fluctuates randomly as you move down a group.

• Metallic character decreases as you move down a group.

Define electronegativity and its significance in bonding.

• Electronegativity is the ability of an atom to repel electrons in a bond.

• Electronegativity is the measure of an atom's size in a molecule.

• Electronegativity refers to the temperature at which a substance melts.

• Electronegativity is a measure of an atom's ability to attract electrons in a bond, significant for determining bond type and molecular properties.

How does electronegativity affect the type of bond formed between two atoms?

• All bonds are always nonpolar regardless of electronegativity.

• Electronegativity determines the type of bond: ionic (large difference), polar covalent (moderate difference), or nonpolar covalent (small or no difference).

• Electronegativity has no effect on bond type.

• Electronegativity only affects the size of atoms, not bond type.

Which element has the highest electronegativity value and why?

• Chlorine

• Fluorine

• Oxygen

• Nitrogen
