What is an ion?

Back

An ion is a charged particle that can be either positively charged (cation) or negatively charged (anion) due to the loss or gain of electrons.

Front

What are noble gases?

Back

Noble gases are a group of elements in Group 18 of the periodic table that are known for their stability and lack of reactivity, including helium, neon, and argon.

Front

How many valence electrons does lithium have?

Back

Lithium has 1 valence electron.

Front

Where are electrons located in an atom?

Back

Electrons are located in the electron cloud surrounding the nucleus of an atom.

Front

What is a covalent bond?

Back

A covalent bond is a type of chemical bond where two atoms share one or more pairs of electrons.

Front

What is the oxidation number?

Back

The oxidation number is a value that represents the total number of electrons that an atom either gains or loses to form a chemical bond.

Front

What are transition metals?

Back

Transition metals are elements found in Groups 3-12 of the periodic table, known for their ability to form various oxidation states and colored compounds.

Front

What is the electron cloud?

Back

The electron cloud is the region around the nucleus of an atom where electrons are likely to be found.

Front

What is the significance of valence electrons?

Back

Valence electrons are important because they determine how an atom can bond with other atoms.
