Flashcard - Valence Electrons and Bonding

Front

What is the atomic number?

Back

The atomic number is the number of protons in the nucleus of an atom, which determines the element's identity.

Front

What are Noble Gases?

Back

Noble Gases are a group of elements in Group 18 of the periodic table that are characterized by their lack of reactivity due to having a full valence shell.

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

How many valence electrons does carbon have?

Back

Carbon has 4 valence electrons.

Front

How many valence electrons does nitrogen have?

Back

Nitrogen has 5 valence electrons.

Front

What is a valence electron?

Back

Valence electrons are the electrons in the outermost shell of an atom that are involved in forming bonds.

Front

What is the significance of valence electrons in bonding?

Back

Valence electrons determine how an atom can bond with other atoms, influencing the formation of molecules.

Front

What is an ionic bond?

Back

An ionic bond is a type of chemical bond formed through the transfer of electrons from one atom to another, resulting in the formation of charged ions.

Front

What is the octet rule?

Back

The octet rule states that atoms tend to bond in such a way that they have eight electrons in their valence shell, achieving a stable electron configuration.

Front

What are periodic trends?

Back

Periodic trends are patterns in the periodic table that show how certain properties of elements change across periods and groups.
