This term we have been working on learning about atoms and the periodic table.
An atom is made up of 3 things. The neutron, proton and electron. The electron is on the outside while the proton and neutron is in the middle which is called the nucleus. Every element has at least 1 atom in it. But the amount of electrons, protons or neutrons depends on the element. The number at the top of an element shows how many electrons there are and the bottom is the neutrons and protons. But the protons and electrons are the same so you take the top number off the bottom. The number left over is the number of neutrons.
The first row on the periodic table is the alkali metals. The metals only have one electron so they want to get rid of it. So they are very reactive. We did an experiment with alkali metals. The first one was lithium. When it got put in water it just spun around. Next we did sodium. It took a few attempts to get the right amount but eventually it set on fire and exploded
