Building Atoms Through Interactive Learning

Mr. Alan provides an instructional video for Year 7 and Year 8 students on using the FET website to assist with home learning. The video guides students through accessing the website, building an atom, and understanding key concepts such as mass number and net charge. Students learn to navigate the atom building screen, use the periodic table, and understand the role of protons, neutrons, and electrons in determining mass number and net charge. The video emphasizes the importance of balancing protons and electrons to achieve a neutral charge.

What is the primary purpose of using the FET website in this lesson?

• To learn about chemical reactions

• To build and understand atoms

• To study the solar system

• To practice mathematical equations

Which window should you open to view the net charge?

• Mass number window

• Periodic table window

• Element details window

• Net charge window

What is the significance of the periodic table in the atom building area?

• It shows the atomic mass of elements

• It indicates the element being built

• It lists the isotopes of elements

• It displays the chemical reactions

Where do electrons need to be placed in the atom building area?

• In the periodic table

• In the shells around the nucleus

• In the nucleus

• In the mass number window

What does the counter in the atom building area track?

• The number of protons, neutrons, and electrons added

• The net charge of the atom

• The total mass of the atom

• The number of atoms built

What happens to the mass number when a proton is added?

• It remains the same

• It decreases by one

• It increases by one

• It doubles

What is the effect of adding a neutron on the net charge?

• It increases the net charge

• It doubles the net charge

• It decreases the net charge

• It has no effect on the net charge

How does the net charge change when an electron is added?

• It increases by one

• It decreases by one

• It doubles

• It remains the same

What is the overall charge when there are equal numbers of protons and electrons?

• Positive

• Undefined

• Zero

• Negative

Which element is formed with two protons and two electrons?
