Pre-Flashcard Periodic Trends

Front

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

Back

Atomic radius increases as you move down a group due to the addition of electron shells.

Front

What is the periodic trend for ionization energy as you move across a period from left to right?

Back

Ionization energy generally increases as you move from left to right across a period due to increasing nuclear charge.

Front

What is electronegativity?

Back

Electronegativity is the ability of an atom to attract electrons in a chemical bond.

Front

Which element has the highest electronegativity?

Back

Fluorine has the highest electronegativity of all elements.

Front

What is a cation?

Back

A cation is a positively charged ion formed when an atom loses one or more electrons.

Front

What is an anion?

Back

An anion is a negatively charged ion formed when an atom gains one or more electrons.

Front

What is the trend for metallic character in the periodic table?

Back

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

Front

What is the significance of the octet rule?

Back

The octet rule states that atoms tend to gain, lose, or share electrons to achieve a full outer shell of eight electrons.

Front

Which group of elements is known as the alkali metals?

Back

The alkali metals are found in Group 1 of the periodic table and include lithium, sodium, potassium, rubidium, cesium, and francium.

Front

What is the atomic radius of potassium compared to gallium?

Back

Potassium has a larger atomic radius than gallium because it is located further down in the periodic table.
