Bohr Model and Lewis Dot Structure Flashcard (Q1W8)

Front

What is the atomic number of an atom?

Back

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

Front

What element does the Lewis Dot Diagram with 3 valence electrons represent?

Back

Al (Aluminum)

Front

What is a valence electron?

Back

Valence electrons are the electrons located in the outermost shell of an atom, which are involved in chemical bonding.

Front

How many electrons can fit on the 1st energy level (orbital) in a Bohr Model?

Back

2 electrons.

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 is the maximum number of electrons in the 2nd energy level (orbital)?

Back

8 electrons.

Front

What does the Lewis Dot Structure represent?

Back

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

Front

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

Back

Subtract the atomic number from the mass number.

Front

What is the significance of the atomic number in the periodic table?

Back

The atomic number determines the position of an element in the periodic table and its chemical properties.

Front

What is the relationship between energy levels and electron configuration?

Back

Energy levels indicate the distance of electrons from the nucleus, and electron configuration describes the distribution of electrons among these levels.
