Periodic Law MEGA REVIEW

Front

What is the Periodic Law?

Back

The Periodic Law states that the properties of elements are a periodic function of their atomic numbers.

Front

What is the significance of electron configuration in determining an element's position in the periodic table?

Back

Electron configuration determines an element's chemical properties and its placement in the periodic table, particularly its group and period.

Front

What happens to 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 happens to atomic radius as you move across a period from left to right?

Back

Atomic radius decreases as you move across a period from left to right due to increased nuclear charge pulling electrons closer.

Front

What is an anion?

Back

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

Front

What is a cation?

Back

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

Front

How does the radius of an anion compare to its neutral atom?

Back

The radius of an anion is larger than that of its neutral atom due to increased electron-electron repulsion.

Front

What is the trend in ionization energy as you move across a period?

Back

Ionization energy generally increases as you move across a period due to increased nuclear charge.

Front

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

Back

Electronegativity generally decreases as you move down a group due to increased distance between the nucleus and bonding electrons.

Front

What is the role of Dmitri Mendeleev in the development of the periodic table?

Back

Dmitri Mendeleev is credited with creating the first widely recognized periodic table and predicting the existence of undiscovered elements.
