Periodic Table and Trends Flashcard

Front

What are nonmetals?

Back

Nonmetals are elements that are typically brittle solids or gases at room temperature and do not conduct electricity well.

Front

What are halogens?

Back

Halogens are elements in Group 17 of the periodic table that have 7 valence electrons and are very reactive.

Front

What happens to ionization energy as you move down a group in the periodic table?

Back

Ionization energy decreases as you move from top to bottom within a group.

Front

Which element reacts violently with water?

Back

Rubidium reacts violently with water.

Front

What is the trend for electronegativity as you move down a group in the periodic table?

Back

Electronegativity decreases as you move down a group.

Front

Define ionization energy.

Back

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

Front

What are alkali metals?

Back

Alkali metals are highly reactive elements found in Group 1 of the periodic table, known for having one valence electron.

Front

What are noble gases?

Back

Noble gases are elements in Group 18 of the periodic table that are inert and have a full valence shell.

Front

Explain the trend of atomic radius in the periodic table.

Back

Atomic radius increases as you move down a group and decreases as you move across a period from left to right.

Front

What is electronegativity?

Back

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