Aubin's PERIODIC TRENDS Test

Front

What is the arrangement of the Modern Periodic Table of Elements?

Back

The Modern Periodic Table is arranged by atomic number.

Front

What are anions and how do they form?

Back

Anions are nonmetals that form negative ions by gaining electrons.

Front

How does electronegativity change across a period and down a group?

Back

Electronegativity increases from left to right within a period and decreases from top to bottom within a group.

Front

Which element has a lower electronegativity value: Calcium or Barium?

Back

Barium has a lower electronegativity value than Calcium.

Front

What happens to the radii of elements in Groups 3-8 as you move from top to bottom?

Back

Elements at the top of the table have smaller radii compared to those at the bottom.

Front

Define atomic number.

Back

The atomic number is the number of protons in the nucleus of an atom, which determines the element's identity.

Front

What is ionization energy?

Back

Ionization energy is the energy required to remove an electron from an atom in its gaseous state.

Front

How does ionization energy change across a period?

Back

Ionization energy generally increases from left to right across a period.

Front

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

Back

Atomic radius decreases from left to right across a period and increases from top to bottom within a group.

Front

What are cations and how do they form?

Back

Cations are metals that form positive ions by losing electrons.
