Science 9 app review

consider a problem: finding out who discovered the element or the atomic number

brainstorm: Googling the element to see if its right

search up pictures of the periodic table.

see if the same person comes up on who found the element.

periodic table 2017

debrief:It works very good.  It has all the elements in the right categories.When click on the elements you can see the atomic number how many protons neutrons and electrons and who discovered the element.  You can also find out which elements are in different categories and you can just search up elements quickly. I t can help with homework if you dont know the right data. It also can help if you don’t wan to do the math to add up the  neutrons it tells you exactly how many there are. Shows pictures of the element.

Elements

  1. What is an element that reacted with many other elements? Which elements did it react with?                                                                                                                 – Chlorine acted with alot of elements. It reacted with lithium, hydrogen, potassium, gold, sodium, And probably alot of other elements.
  2. What is an elements that did not react with any elements? Which elements did it not react with?                                                                                                                                                             – Helium. It didn’t react with chlorine.

  3. Why do you think some elements reacted with each other and others didn’t?                                – I think that some elements didn’t react with eachother because they cancel eachother out and that the ones that react together have made a new element.

  4. Do you think there may be a pattern to how the periodic table is arranged? Does it relate to how elements react with each other?                                                                                                                        – I think the periodic table is arranged by different groups of materials and how strong/reactive they are.
