In science we prove many things in the world, we prove how certain things are held together. The perodic table is a fantastic way to figure out how thigs are made and what they are made of. Each element has a certain number of electrons, protons, and nuetrons, which make up the element and lets it produce new things. Each element has its on diagram sayign how many eletrons there are in the shells. The …showed first 75 words of 305 total…

When you lose eletrons you have to make the element a positive ion because the number of protons are greater then the number of eletrons. When you gain eletrons then it is a negative ion because the number of protons are less then the number of eletrons. There are many more things about ions but that is a basic grade 9 lesson.
