Document Summary

Consist of matter which is anything that occupies space and has mass. Mass: is the amount of matter in any object which does not change. Weight does not change and is the force of gravity acting on matter. 3 states, solid, liquid and gas solid has a shape( ex. 27 different elements are present in the body but 4 major ones are about. 96% of body mass the 4 elements are calcium, potassium, sulfur, sodium, chloride, magnesium, iron and phosphorous. Additional 14 elements are called trace elements that are in tiny amount in the body. Atoms are the smallest unit of matter that retain properties and characteristics of the elements. Lots of different subatomic particles compose individuals atoms ( ex, protons, neutrons, and electrons) Nucleus: the dense core center of an atom. Protons: + charged, neutrons (uncharged or neutral), and electrons( - charged and move in larger space around the nucleus. ) Electron shell: is a simple circle around he nucleus.
