Bohr and Lewis Dot model

Front

What is the Bohr model of the atom?

Back

The Bohr model describes the atom as having a central nucleus surrounded by electrons that travel in fixed orbits at specific energy levels.

Front

What is the Lewis Dot model?

Back

The Lewis Dot model represents the valence electrons of an atom as dots around the element's symbol, illustrating how atoms bond with each other.

Front

What is a Group in the Periodic Table?

Back

A Group is a column in the Periodic Table that contains elements with similar chemical properties and the same number of valence electrons.

Front

What is an electron?

Back

An electron is a negatively charged subatomic particle that orbits the nucleus of an atom.

Front

How many electrons can fit in the second energy level?

Back

The second energy level can hold up to 8 electrons.

Front

What are energy levels in an atom?

Back

Energy levels are the fixed distances from the nucleus where electrons can be found, each level can hold a specific number of electrons.

Front

What is the significance of valence electrons?

Back

Valence electrons are the outermost electrons of an atom and are important for determining how an atom will bond with others.

Front

What is a dot diagram?

Back

A dot diagram, or Lewis structure, visually represents the valence electrons of an atom and how they are shared or transferred in chemical bonds.

Front

What is the maximum number of electrons in the third energy level?

Back

The third energy level can hold up to 18 electrons.

Front

What is the nucleus of an atom?

Back

The nucleus is the central part of an atom, containing protons and neutrons, and is positively charged.
