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 energy levels.

Front

How many electrons can fit in the first energy level of an atom?

Back

2 electrons.

Front

What is a Lewis Dot Structure?

Back

A Lewis Dot Structure is a diagram that shows the bonding between atoms of a molecule and the lone pairs of electrons that may exist.

Front

What does the mass number of an atom represent?

Back

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

Front

How many valence electrons does Carbon have?

Back

4 valence electrons.

Front

What element is represented by the Lewis Dot Structure with 3 dots?

Back

Aluminum (Al).

Front

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

Back

8 electrons.

Front

What is the significance of valence electrons in chemical bonding?

Back

Valence electrons determine how an atom can bond with other atoms.

Front

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

Back

Subtract the atomic number (number of protons) from the mass number.

Front

What is the atomic number of an element?

Back

The atomic number is the number of protons in the nucleus of an atom.
