In this lab we used an app called elements 4d to try to get reactions from different elements.
An element that reacted with many other elements is oxygen. (O) It reacted with hydrogen. (H)
An element that did not react with any other elements is bismuth. (BI) It did not react with sodium. (NA)
I think that some elements reacted together because some elements are missing a proton and a element that had an extra proton could of gave that element to a different element.
The table is organised by how many protons the elements have. I think that where the elements are placed that they will react with in the columns and rows. example sodium is in the red column and bismuth is in green column. So they don’t react but hydrogen and oxygen are both in the dark blue column so they react.
