MATTER AND ATOM
MATTER Matter is everything that extends in a certain region of spacetime, has a certain amount of energy and therefore is subject to changes in time and interactions with measuring devices. It is considered to be what forms the sensitive part of the objects perceptible or detectable by physical means. ATOM Each Atom is composed of one nucleus and one or more electrons attached to the nucleus. The nucleus is composed of one or more protons and typically a similar number of neutrons. Protons and neutrons are called nucleus more than 99,94% of the atom´s massif the Nucleus. Protons have a positive electrical charge, electrons have a negative electrical charge and the neutrons have both electrical charges, making them neutral. If the number protons and electrons are equal, that atom is electrically neutral.
