Chemistry Bonding Basics

Front

What is a positive ion?

Back

A positive ion is an atom that has lost one or more electrons, resulting in a net positive charge.

Front

What is the octet rule?

Back

The octet rule states that atoms tend to gain, lose, or share electrons in order to have eight electrons in their valence shell, achieving a stable electron configuration.

Front

Why do chemical bonds form?

Back

Chemical bonds form to fill the valence shell of electrons for the elements involved, leading to greater stability.

Front

What is the difference between ionic and covalent bonds?

Back

Ionic bonds involve the transfer of electrons from one atom to another, while covalent bonds involve the sharing of electrons between atoms.

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

How do you determine the number of valence electrons in an element?

Back

The number of valence electrons can be determined by the group number of the element in the periodic table.

Front

What is the formula for barium nitride?

Back

The formula for barium nitride is Ba3N2.

Front

What is an ion?

Back

An ion is an atom or molecule that has a net electrical charge due to the loss or gain of one or more electrons.

Front

What is the significance of the proton number in an ion?

Back

The proton number (atomic number) determines the identity of the element and remains unchanged when an atom becomes an ion.

Front

What happens to an atom when it gains an electron?

Back

When an atom gains an electron, it becomes a negative ion (anion).
