The Periodic Table Of Elements (2/8-2/12)






http://sciencenotes.org/printable-periodic-table/

Summary:

Have you ever heard of a periodic table and wondered what it is? Do you know what an element is? If you want to know more, than you are at the right place!

Elements of the Periodic Table.

Look at the elements in the periodic table above. In the top left corner there is a number, and the elements are in numerical order. That number is the atomic number. Each element has a different atomic number. The atomic number is the number of protons in the atomic nucleus.
On the top right corner there is another number. This number is the melting point of an element. This number is usually in C°. Some of the elements say "unknown" because scientists have not figured out yet what the melting point is. Example of a melting point: The melting point for titanium (Ti) is 1668 C°.

Each row in the periodic table is called a period. There are 7 periods in a periodic table. The first period only has 2 elements! (Hydrogen, and helium.) Do you know which row has 32 elements? It is the 6th period. The elements in rows have different properties.
The columns in the periodic table are called groups, or families. There are 18  groups. Each  element in a group has a similarity. Think about it like this: The families look alike, and have similar properties just like in real life, but the neighbors (periods) are close, but they do not look the same, they do not have the same properties. Just like in the periodic table! 

Atoms and their Structure

Are you wondering what an atom is? Matter is made from atoms. Practically everything is made from atoms! But... are you wondering what an atom looks like? Well that is pretty difficult because atoms are super, super large. There is something easy about atoms though: they are made out of some easy parts. They include the nucleus (protons and neutrons) and electrons.

 Imagine an atom like our solar system...

 Are you wondering what the nucleus is? The nucleus is the center of the atom. Imagine the nucleus as the sun. Inside of the nucleus there are 2 parts: the proton, and the neutron.

 The proton has positive charge. Some atoms have many protons, but some atoms (e.g., hydrogen atoms) only have 1 proton! It depends on the type of atom. A proton is part of the nucleus. If the atom was the size of a football field, then the proton would be smaller than a marble. If you think that an atom is small, think about the proton inside of it!!

The other part to the nucleus is a neutron. The neutron has a lot of mass, but no charge, it is neutral. All neutrons look the same. The number of neutrons affects the mass, and the radioactivity of the atom.

 Another part of an atom is the electron. The electron are pieces of electricity that move from one atom to another.  They are negatively charged. You might be thinking how small a proton is now, but electrons are even smaller!

 When elements are in their usual form, they have the same number of electrons as protons. When they change their state, that number could be different.

 Here's a joke just for you!!!
An atom walked into his classroom looking very sad.
The teacher asked him "Why are you sad?"
The atom replied "I lost and electron."
The teacher said "Are you sure?" 
"Yes, I'm positive!" replied the atom. 

SP8: Obtain, evaluate and communicate information

This week our class engaged in discussions with scientific peers. We worked on a few documents to get more understanding about the periodic table. We analyzed data from a few presentations, and we worked with our table groups to write a sentence each about what we learned that day. I learned a lot this week with my table group.

Fun Facts!
  • The only letter that is not in the periodic table is "J".
  • Every name in the periodic table has a symbol that is not always based on the element. Example: The symbol for silver is Ag.
  • Francium (Fr) is the rarest element on earth.
  • Argentina is named after the element silver.
  • 90/109 elements are found in nature.
  • 19/109 elements are only created in a laboratory
  • 5 of the elements are named after people (Einsteinium after Einstein ... and 4 more)

https://image.slidesharecdn.com/theperiodictable-110223090122-phpapp01/95/the-periodic-table-7-728.jpg?cb=1298451775 Summary: This week, we have been learning about how the periodic table is arranged and the different patterns that are in the rows  and columns. 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...
