Bell Ringer: Structure of an Atom

1. Open the ¨Oct 1, 2020: Bell Ringer¨ assignment
2. Use the image on this slide to answer the questions in the form

Structure of an Atom

• A: Protons

• B: Neutrons

• C: Electrons

• D: Electron cloud, Valence shell, Orbital

• Nucleus

Name the structures

• Atomic Mass

• Atomic Number

• Element Name

• Element Symbol

Multiple Select

What is the atomic number?

• Protons

• Electrons

• Neutrons

Fill in the Blank

The number of electrons is equal to the number of __________.

Multiple Select

What is the atomic mass?

• Protons

• Neutrons

• Electrons

Electrons move in specific areas outside the nucleus

• Orbit = to move around (like the earth orbits around the sun)

• Each orbital can only hold a certain amount of electrons

S orbital

• The first orbital is the S orbital

• It can only hold 2 electrons

P orbital

• The second orbital is the P orbital

• It can only hold 6 electrons

D orbital

• The third orbital is the D orbital

• It can only hold 10 electrons

F orbital

• It can only hold 14 electrons

Using the periodic table to understand electron configuration

• s orbital = blue

• p orbital = green

• d orbital = pink

• f orbital = yellow

How to write electron configuration

• Identify the row number

• Identify the orbital

• Identify the number of electrons in the orbital (based on the position on the periodic table)

• Write out all configurations for the elements prior
