Understanding the Periodic Table and Its Trends

What does the period number in the periodic table indicate about an atom?

• The number of electron shells

• The number of neutrons

• The number of valence electrons

• The number of protons

How does atomic radius change as you move across a period from left to right?

• It increases

• It decreases

• It remains constant

• It fluctuates randomly

What happens to the size of cations compared to their parent atoms?

• Cations are smaller

• Cations are larger

• Cations have a variable size

• Cations have the same size

Why is ionization energy higher as you move across a period?

• Electrons are further from the nucleus

• The atomic mass increases

• More electron shells are added

• There are more protons attracting the electrons

Which element is known for having a high electron affinity due to its small size?

• Neon

• Chlorine

• Oxygen

• Fluorine

Why do noble gases not follow the electron affinity trend?

• They have incomplete outer shells

• They have variable electron configurations

• They have full outer shells

• They are highly reactive

What is the relationship between electronegativity and atomic size?

• No relationship

• Inversely proportional

• Varies with temperature

• Directly proportional

What was the most recent revision to the periodic table about?

• The discovery of a new element

• The atomic weight interval of argon

• The reactivity of noble gases

• The electron configuration of transition metals

Which country is named after an element in the periodic table?

• Australia

• Argentina

• Germany

• India

What is the Latin name for the element silver?

• Ferrum

• Plumbum

• Argentum

• Aurum
