BONDING BASICS

Front

What is a chemical formula?

Back

A chemical formula is a combination of chemical symbols and numbers that indicates which elements are present in a molecule and how many atoms of each element are present.

Front

What is a double bond?

Back

A double bond consists of two pairs of shared electrons between two atoms.

Front

Do covalent compounds have stronger bonds than ionic compounds?

Back

No, covalent compounds generally have weaker bonds than ionic compounds.

Front

What is the group number for elements with a stable number of electrons in their outer energy level?

Back

Group 18 elements have a stable number of electrons in their outer energy level.

Front

How many valence electrons must an element have to be considered stable (except for hydrogen and helium)?

Back

An element must have 8 valence electrons to be considered stable.

Front

What is an ionic bond?

Back

An ionic bond is a type of chemical bond that occurs when one atom transfers electrons to another atom, resulting in the formation of charged ions.

Front

What is a covalent bond?

Back

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

Front

What are valence electrons?

Back

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

Front

What is the octet rule?

Back

The octet rule states that atoms tend to gain, lose, or share electrons to achieve a full outer shell of 8 electrons.

Front

What is a molecule?

Back

A molecule is a group of two or more atoms bonded together, representing the smallest fundamental unit of a chemical compound.
