Phosphorus

https://www.brightagrotech.com/wp-content/uploads/2013/10/Phosphorus.png

Phosphorus is the 15 element. That means that phosphorus has 15 electrons and protons. Phosphorus was the 13 element that was ever discovered. It was discovered by man named Hannig Brand. When Hannig Brand discovered it he was in Germany in 1669. Phosphorus has an atomic mass of 30.94. Phosphorus is a non-metal element. At room temperature it is a solid.

I used scientific text to find out about phosphorus. I did this so that I could complete a project or thought and back it up with evidence. I also so did this because it would make sure that what I said on my project wasn't true or could be misunderstood.

Atoms and what makes up this earth the place where we live

An atom is what makes up the earth and everything we know of. An atom is made up of four things, a nucleus, protons, neutrons, and electrons. The nucleus is the center of the atom, protons and electrons are the things that make it. A proton it what makes up the nucleus, it is also what gives an element on the periodic table of elements it's periodic number. Let's say that a atom has 3 protons then it has a periodic number of 3. Also a proton has an positive electric charge, that is why some people put plus signs on it when they draw it. 

A neutron is another part that makes up the nucleus, a neutron has a neutral electric charge. An electron travels around the nucleus and creates almost a barrier around it, fun fact the number of protons in an atom is the same as the number of electrons let's say you had 9 protons you would have 9 electrons. Electrons have a negative charge.

An element is made up of molecules. A molecule is when two or more of the same type of atom chemically bind together. When we make these into elements then we can sort them in the periodic table of elements which is organised by periodic number. A periodic number in the number of protons in an atom, each substance or element has it's own periodic number, like hydrogen has a periodic number of 1.

A mixture is when two different substances or elements are forced to mix together by physical bonds, when this happens no chemical reaction occurs so that makes it so you can separate the two substances or elements from one another. This is like a compound but they can be taken apart. 

A compound is when two different substances or elements combine chemically so that a chemical reaction occurs. Once this happens their is no going back and you can not separate them again. You know that a chemical reaction has occurred when your senses sense something different about the substance.

In science I explained molecules, atoms, compounds, and mixtures. I did this by making sure that all the detail that was needed to be able to explain this in a kid friendly way but still complicated enough for grown ups and older kids to understand. I also made sure that my work was correct by using the stuff that my teacher said and paraphrasing it to a way that it had the proper and right meaning. Then I wrote about it which finished the explanation through my work properly and efficiently. 

why matter maters to us.

What is matter?

Matter is anything that takes up space and has mass in volume. Matter is what makes the world and everything in it. If their was no matter we wouldn't be here. Anything that is solid, liquid, gas, plasma, or Be condensates is matter, this is because if the objects fall into these categories they are in states of matter so that makes it matter.

Two things can happen to matter! What are those two?

The two things that can happen to matter is a physical change and a chemical change. A physical change is when you take a piece of paper and you rip cut or fold it. do you still have paper? Yes! Like if you take a pencil or a stick and break it on you knee it is still wood right ? Yes! So basically a physical change is when something happens to something that is matter but is t changes how it looks but it is still a what it was when it had no changes.

A chemical changes in matter is when something happens to matter so that it forms new matter or something new. An example of chemical changes in matter if burning. Lets say you have wood or a piece of paper and you set it on fire once the fire burns out then you have ashes. Is that the same as before it caught on fire? No! Another example of chemical changes in matter is when you bake a cake are the ingredients the same now that you have cooked them?No!

A list of physical changes in matter:                                               A list of chemical changes in matter:

                                                                           

• cutting                                                                                      burning
• folding                                                                                      rusting
• write on                                                                                    cooking
• tear
• painting

I confirmed that backing powder was the mysterious substance by seeing how it reacts to substance and do substances we know and seeing if they act the same way and if they do then they are the mysterious substance. This is connected to matter because it is showing how different atoms act when meting others and the reactions that happen.
