What does the periodic table show us? it shows us what the elements are and how many electrons, neutrons and protons have. it explains how much matter is inside of them, says how many protons, electrons, neutrons. it shows how many shells it has and shows the position on the periodic table. Alkali metals have 1 electron in the outer shell. they need to get rid of it so they can react. atoms are made up of 3 things, electrons, protons, neutrons. the electron it on the outside while the proton and neutron are in the middle. the centre of the atom is called a nucleus. every element has at least one atom in it. the number at the top of the element shows how many electrons there are, and at the bottom is the neutrons and protons.
We did an experiment where you put water and universal indicator in, then miss put lithium in first, it just smoked and spun around in circles, but then she did a bigger chunk and it made it spin way faster and smoke more. then after a while she put in sodium, the small piece smoked ALOT. then she got a bigger piece and put it in, and eventually it caught on fire and exploded, all the little bits that were caught on fire went all over the tables.
