Blog 2.2 Bag of Ions & Periodic Table Activities.

The Periodic table is a grid made of Rows ( or periods ) that proceed horizontally from left to right across the table, members of the same period have the same energy levels. The grid is also made of Columns ( or groups)  which represent groups or families on the table that proceed vertically ( from top to bottom ) , members of the same column have the same number of valence electron and also have similar chemical properties are found in the same group.

The similarity between an atom and an ions of the same element is that they have the same number of protons and symbol.

Ions and atom of the same element are also different, an ion is an element that has lost or gained electrons while atoms stay the same and have the same number of protons and electrons.

Ions forms when an element wants to have 8  for valence electrons or lose one to be an octet. 

You can predict the charge on an ion by looking at the valence electrons which is the last number in the electron configuration and also based on the location of the element in the periodic table. If the electron configuration is 2-8-8-2, the ion will lose 2 to be an octet which mean the new electron configuration will be 2-8-8.

Lab 2.1: Grouping of Elements

1. In the periodic table consists of 8 groups: metals, non-metals, noble gas, mettaloids, alkali metals, transition metals, alkaline earth metal and halogens. In my lab i classified Carbon, Phosphorus and Sulfur as non-metals and also classified Aliminum, lead and tin as metals. And the last one that i did was Silicon which i classified as a mettaloids.
2. The four properties that we tested in our lab were appearance, Electrical conductivity, Crush test and Reactivity with acid. Appearance has a physical property because you can figure out if the element if dull or shiny just by looking at it and it won't make a chemical change. Electrical Conductivity has a physical property as well because there was no new substance formed. In order to figure out the hardness of an element you had to conduct a crush test in order to find its malleability, which as well has a physical property because it only increase the surface area of the element,its not creating anything new.The reactivity with acid has a chemical property because reactions occured and new substances formed.  
3. Metalloids have properties of both metals and non-metals,so they can normaly be ruled as both.Or just metalloids,the only element we tested in this lab and considered a metalloid was Silicon. the name and symbol of all metalloids. B = boron, Si= silicon, Ge=  germanium, As= arsenic, Sb= antimony, Te= tellurium, At= astatine. 
4. When you look at the periodic table of elements,  and our lab you can see that as you go from left to right the elements become less metallic, and as you go from top to bottom the elements become more mettalic.  As you proceed from elements near to the top you can see that they're more metallic and as you go near the bottom of the periodic table they become less metallic.
5. One of the elements that has a symbol that doesnt correlate with his name is Gold. The symbol of Gold is Au. There's no a in Gold or either a u. No need to fear, there's a reason for this,  it's because Gold recieved the symbol Au from the latin name for gold, aurum, which translate to " shining dawn " in english.
