Student Exploration: Average Atomic Mass

Name:

Educatee Exploration: Average Atomic Mass

Directions: Follow the instructions to go through the simulation. Respond to the questions and

prompts in the orange boxes.

5 ocabulary: boilerplate atomic mass, isotope, mass defect, mass nugrandber, mass spectrometer, nuclear binding

energrandy, unified diminutive mass unit, weighted average

Prior Knowledge Questions (Do these BEFORE using the Gizmo.)

1. In the image to the correct, the cans of soup take different

masses. Without doing the mathursday, approximate the average mass

of a tin can of soup.

Estimate:

2. Now calculate the average mass past adding up the masses of all the cans and dividing by the total number

of cans.

A. What is the average mass of a can of soup?

The average mass of a tin can of soup is

200g.

B. How shut was your prediction?

I predicted it would be 300g without

doing any math, so I was 100g off from

the bodily average mass. I did however,

figure information technology would be somewhat of a lower,

more generalized size.

Gizmo Warm-up

Merely like cans of soup, atoms of the same element ofttimes accept different

masses. These different varieties are chosen i and thentopes. In the Average

Atomic Mass Gizmo, you will learn how to find the average mass of an

element using an instrument called a m ass spectrometer.

To brainstorm, cheque that Carbon is selected and the Isotope mix is Custog.

Use the sliders to add together about twenty atoms each of Carbon-12 and

Carbon-13 to the chamber.

ane. In the mass spectrometer, atoms are vaporized (turned into a gas) and ionized (stripped of electrons). The

charged particles are then shot through a tube surrounded by electromagnets. Click Release atoms and

observe the particles as they hit the deasttector.

A. Do the ions travel in a straight path or a curved path?

The ions travel in a curved

path.

B. Which atoms are deflected the most by the magnetic field?
