Bohr and Lewis Model

Front

What is the atomic number of an element?

Back

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

Front

What is the mass number of an atom?

Back

The mass number is the total number of protons and neutrons in the nucleus of an atom.

Front

What does the Bohr Model represent?

Back

The Bohr Model is a simplified representation of an atom that depicts electrons orbiting the nucleus in defined paths.

Front

How does the atomic number relate to the periodic table?

Back

Elements in the periodic table are arranged in order of increasing atomic number.

Front

What is the relationship between protons and neutrons in an atom?

Back

The number of protons and neutrons can vary in different isotopes of the same element, but the number of protons defines the element.

Front

What is an isotope?

Back

Isotopes are variants of a particular chemical element that have the same number of protons but different numbers of neutrons.

Front

What is the significance of the atomic mass?

Back

The atomic mass is the weighted average mass of an element's isotopes, measured in atomic mass units (amu).

Front

What does the term 'valence electrons' refer to?

Back

Valence electrons are the electrons in the outermost shell of an atom that are involved in chemical bonding.

Front

What is the difference between the Bohr Model and the Lewis Structure?

Back

The Bohr Model shows electron orbits around the nucleus, while the Lewis Structure represents the arrangement of valence electrons in a molecule.

Front

What is the role of protons in determining an element's properties?

Back

Protons determine the element's identity and its position in the periodic table, influencing its chemical properties.
