Properties of elements flashcard

Front

What is the most likely reaction between Lithium and Oxygen?

Back

Lithium and oxygen react to form lithium oxide.

Front

What is the electron configuration characteristic of elements in the 1st column of the periodic table?

Back

Elements in the 1st column have one valence electron.

Front

What do elements in the 17th column of the periodic table need to do to achieve a full outer electron shell?

Back

They need one more electron to fill their outer shell.

Front

What is a defining property of elements in the 18th column of the periodic table?

Back

They are very stable and not reactive.

Front

Which element is the best conductor of electricity among Carbon, Lithium, and Krypton?

Back

Lithium is the best conductor of electricity.

Front

What is a valence electron?

Back

A valence electron is an electron in the outermost shell of an atom that can participate in chemical bonding.

Front

What is the significance of the periodic table's columns (groups)?

Back

Elements in the same column have similar chemical properties and the same number of valence electrons.

Front

What is the general trend in reactivity for alkali metals (1st column) as you move down the group?

Back

Reactivity increases as you move down the group.

Front

What are noble gases, and where are they located in the periodic table?

Back

Noble gases are located in the 18th column and are characterized by their lack of reactivity.

Front

What is the electron configuration of a typical alkali metal?

Back

Alkali metals have one electron in their outermost shell, e.g., Lithium: 1s² 2s¹.
