Introduction
An atom is the smallest constituent unit of ordinary matter that has the properties of a chemical element. Every solid, liquid, gas, and plasma is composed of neutral or ionized atoms.
From this material students can learn about the atom and the structure of it.
The student has to watch a video "What Is An Atom?" (the link is available in the credits) and read 10 statements based from the video material and decide if the statement is correct or incorrect.
After the answers have been filled in, the student has the check his/her answers and estimate their knowledge in this subject.
Task
- Watch the video - "What Is An Atom?" (the link is given in the credits)
- Read 10 statements about the topic in the video material and decide whether the statement is "Correct" or "Incorrect"
- If the statement is "Incorrect", then rewrite the statement correctly.
- Evaluate yourself and make a conclusion about your knowledge in this topic.
Process
- Atom is the smallest particle of an element that retains the elements properties.
- Atom is the smallest particle.
- Atom has a dense center called a neutron.
- Neutrons have neutral electric charge.
- The atom center consists of protons and electrons.
- Every element has the same number of protons.
- Electrons are positively charged and Protons are negatively charged.
- Electrons and protons attract to each other.
- The atomic number is protons present in the atom.
- Individual atoms can only gain electrons.
Evaluation
- Atom is the smallest particle of an element that retains the elements properties. Correct
- Atom is not the smallest particle. Incorrect
- Atom has a dense center called a nucleus. Incorrect
- Neutrons have neutral electric charge. Correct
- The atom center consists of protons and neutrons. Incorrect
- No element has the same number of protons. Incorrect
- Electrons are negatively charged and Protons are positively charged. Incorrect
- Electrons and protons attract to each other. Correct
- The atomic number is protons present in the atom. Correct
- Individual atoms can either gain or loose electrons. Incorrect
Conclusion
For every correct answer you can get 2 points. If the statement is incorrect, but you can not rewrite the statement correctly or wrote it incorrectly, then you get only 1 point.
- 20-18 p. - GREAT JOB (You understand this subject extremely well)
- 18-10 p. - YOU COULD DO BETTER (You do not understand this subject well, you should repeat again)
- 10-0 p. - TRY AGAIN (you do not understand this subject that well, you should try again and start from the beginning)
