Bohr Models

Front

What are valence electrons?

Back

Electrons in the outer shell of an atom that determine its chemical properties.

Front

What is the atomic number?

Back

The number of protons in the nucleus of an atom, which defines the element.

Front

What is the mass number?

Back

The total number of protons and neutrons in an atom's nucleus.

Front

What particles are found in the nucleus of an atom?

Back

Protons and neutrons.

Front

How do you determine the number of neutrons in an atom?

Back

Subtract the atomic number from the mass number.

Front

What is an atom?

Back

The smallest unit of matter that retains the properties of an element.

Front

What is the difference between an element and a compound?

Back

An element is a pure substance made of one type of atom, while a compound is made of two or more different types of atoms chemically bonded together.

Front

What is the significance of the periodic table?

Back

It organizes elements based on their atomic number, electron configuration, and recurring chemical properties.

Front

What is an ion?

Back

An atom or molecule that has gained or lost one or more electrons, resulting in a net charge.

Front

What is the role of electrons in chemical bonding?

Back

Electrons, particularly valence electrons, are involved in forming bonds between atoms.
