Bohr and Lewis Dot model

Front

What is the Bohr model of the atom?

Back

The Bohr model describes the atom as having a nucleus surrounded by electrons that travel in fixed orbits or shells around the nucleus.

Front

What does a Lewis Dot Structure represent?

Back

A Lewis Dot Structure represents the valence electrons of an atom, showing how they are arranged around the atomic symbol.

Front

How many valence electrons does Fluorine (F) have?

Back

Fluorine has 7 valence electrons.

Front

What is the significance of the Periodic Table?

Back

The Periodic Table organizes all known elements based on their atomic number, electron configuration, and recurring chemical properties.

Front

What is a valence electron?

Back

A valence electron is an electron that is located in the outermost shell of an atom and can participate in chemical bonding.

Front

How many valence electrons does Phosphorus (P) have?

Back

Phosphorus has 5 valence electrons.

Front

What is the outermost shell of an atom called?

Back

The outermost shell of an atom is called the valence shell.

Front

What is the difference between an isotope and a valence electron?

Back

An isotope refers to atoms of the same element with different numbers of neutrons, while valence electrons are the electrons in the outermost shell that determine chemical bonding.

Front

What is the purpose of a Lewis Dot Diagram?

Back

A Lewis Dot Diagram is used to visualize the arrangement of valence electrons around an atom and to predict how atoms will bond.

Front

What is the electron configuration of Neon (Ne)?

Back

The electron configuration of Neon is 1s² 2s² 2p⁶.
