Bohr Model and Lewis Dot Structure Flashcard (Q1W8)

Front

What is the Bohr Model?

Back

The Bohr Model is a representation of the atom that depicts electrons orbiting the nucleus in defined paths or energy levels.

Front

What does a Lewis Dot Structure represent?

Back

A Lewis Dot Structure represents the valence electrons of an atom and how they are arranged in bonds with other atoms.

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

How do you determine the mass number of an atom?

Back

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

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 bonds with others.

Front

How many valence electrons does Magnesium (Mg) have?

Back

Magnesium has 2 valence electrons.

Front

What is the correct Lewis Dot Structure for Oxygen (O)?

Back

The correct Lewis Dot Structure for Oxygen has 6 dots representing its 6 valence electrons.

Front

What is the electron configuration of Lithium (Li)?

Back

The electron configuration of Lithium is 1s² 2s¹.

Front

What is the difference between an atom and an ion?

Back

An atom is neutral, while an ion has a net charge due to the loss or gain of electrons.

Front

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

Back

The maximum number of electrons in the first energy level is 2.
