Elements, Ions and Isotopes (9/4-9/8)

https://qph.ec.quoracdn.net/main-qimg-4c093d923cef8c8e3752f2f7a7f40450

Summary:
This week, we learned about elements, ions, and isotopes. You have probably heard of the periodic table of elements. Elements are the alphabet to the language of molecules. Another way to think about it is that they are the building blocks to matter.

 How can you learn about a specific element by looking at it on the periodic table of elements? There are 4 important properties of an element on the periodic table. The atomic number displays the number of protons. Then, there is the element symbol, which is an abbreviation of the element name. This symbol has no numbers and is never more than two characters. There is the atomic mass or weight, which has the number of protons and neutrons, and finally is the element name, simply the name of the element.

 Ions are atoms that have lost or gained electrons. If they have lost electrons, they are called cations. Cations are positive because they have lost electrons, which have a negative charge. Therefore, it becomes positive. Anions are atoms that have gained electrons. This makes them negative because of the negative charge. To determine the change, it is the number of protons - the number of electrons.

 Isotopes are atoms that have the same number of protons, but a different number of neutrons. The average atomic mass that is shown in the periodic table is the weighted average of isotopes. Isotopes are used a lot in scientific applications, or resources such as medicine and more.

SP6: Constructing Explanations and Designing Solutions

This week, I constructed an explanation of elements, ions, and isotopes when filling out worksheets and watching different videos. This has helped me understand how elements work and use evidence to back up my explanations. I designed different solutions of how elements, ions and isotopes and how they are used by looking at different explanations and understanding what it means. 


XCC: Structure and Function

When an atom has a different amount of electrons, this affects the structure of the atom. This changes the function because there is a different charge. By adding electrons, the function or charge becomes negative. When removing electrons, the charge becomes positive. This relationship between structure and function compares to matter and how the atoms move around because the atoms are causing the matter, or function to change.

Multiplier

This week, I was a wanderer. Whenever I had an idea or found something interesting, I shared it with my group to see what they thought. When we did different activities in class, I learned a lot of new important information. When I figured it out, I shared what I learned. I tried to be an active contributor to the team and share my findings.

In the periodic table, the rows are called periods. Along the rows, the elements are organized by atomic number (the number of protons.) The rows also have the same energy level or the number of electrons. For example, in the first row, all of the elements' atoms have one energy level, and so on.The atomic mass is the number of neutrons plus the number of protons. The atomic mass can be a decimal, and it is ordered increasingly. The columns in the periodic table are called groups or families. Each family has a name. For example, group one is composed of alkali metals which is the family with Lithium, Sodium, and more. Each group also has the same number of outer, or valence electrons. The elements in group one ...

Musical Instruments and Sound- Weekly Blog (3/11-3/15)

Sound Energy - Musical Instruments by SolPass Summary We understand how sound is produced, and how sound waves can travel through different mediums, but how do musical instruments produce sound? There are hundreds of instruments in the world, producing various pitches, tones, and chords. There are three main types of instruments: wind, percussion, and string. The sound is produced differently based on the type of instrument. The first type of instrument is a string instrument. In a string instrument, the sound is created from the vibration of strings. For example, when you play guitar, you pull on the strings. As the strings vibrate, the air molecules start vibrating as well, producing sound. The next type of instruments are wind and brass instruments and are made when we blow sound into them. The shape and position of the instrument affect the overall tone and pitch. The most common kind of wind instrument is a reed instrument. Blowing on the reed causes it to vib...

Energy Transformations - Weekly Blog (1/28-2/1)

Types of Energy  by  Solar Schools Summary: You've probably heard the quote by Albert Einstein, "Energy cannot be created or destroyed, it can only be changed from one form to another." But what are the forms of energy? There are six general energy forms: chemical, mechanical, thermal, light, electrical, and nuclear. Any form of energy can be converted into another form. There are many examples of energy transformations that happen in our everyday lives. The first energy form is chemical energy. Chemical energy is a form of potential energy and is stored in chemical substances. An example of chemical energy is gasoline that is used to power a car. The next form of energy is mechanical energy. Mechanical energy is energy released by a moving object. For example, mechanical energy is the energy that causes a soccer ball to move when kicked. Another form of energy is thermal energy and is associated with the motion of molecules. This means that it is caused by f...
