Atomic Structure Advanced

Atoms structure (advanced)

SWBAT: Understand fully what the atom is, and what it consists of

​In 1794 Dalton became the first to describe color blindness

- He took Democritus Idea of Atoms and developed it.

Science Joke....

Do you know why we can't trust Atoms? ...

​

The ATOM

​Blank Side	​Lined Side
​The Atom	​Dense Center (protons, Neutrons) and Electrons orbit around it.

Multiple Choice

Which of these correctly describes the atom?

• A dense Center made of Protons and Neutrons, with Electrons orbit the center

• A nucleus made up of Electrons and Protons, with Neutrons orbiting around it

• A nucleus made of Neutrons and Electrons, with Protons orbiting around it

REMEMBER and write in Index Cards

Counting Mass and Neutrons

​Blank Side	​Lined Side
​M-A=N	​Mass- Atomic Number(protons)= Neutrons
​A=P=E	​Atomic #=Protons=Electrons

Hotspot

Which of these particles contain mass of 1amu

Multiple Choice

Describe the element Barium (Ba). Tell me the amount of each particle if Barium (Ba) has a mass of 135amu.

• 56 Protons

  79 Neutrons

  56 electrons

• 56 Protons

  79 electrons

• 56 Protons

  56 Neutrons

  56 electrons

• 79 Protons

  79 Neutrons

  56 electrons

Multiple Choice

An atom has a mass of 20amu. It has 11 Protons. How many Neutrons and Electrons does it contain?

• 9 Neutrons

  11 Electrons

• 10 Neutrons

  10 Electrons

• 8 Neutrons

  12 Electrons

• 12 Neutrons

  8 Electrons

​The charge is not the same as mass. Charge is about the electrical charge it contains.
Electrons- Negative
Neutrons - none
Protons -Positive

Count them like soldiers of diff teams.

Charge

​Blank Side	​Lined Side
​Charge	​Inside the Nucleus there is always a positive Charge.
