Running head: UNIT 3: WAVE LENGTHS AND THE ATOM Wave Lengths and the Atom Nature of waves James Trefil and Robert M. Hazen (2011) stated, “The nature of wave’s travel through the speed of light, and life on earth is transmitted through space by such a wave” (p. 118. para. 3). Waves occur in one’s daily life; all of such waves must move through matter (p. 118, para. 1). Radio waves allow transmission of music, microwaves assist in heating and cooking food, and X-rays are used by dentists

Tevlin October 5, 2015 6. Briefly describe the structure and size of an atom. How big is the nucleus in comparison to the entire atom? Atoms are extremely small; millions of atoms could fit end to end across a period at the end of a sentence. Protons and neutrons are found in the tiny nucleus at the center of the atom. The rest of the atom’s volume is made up of electrons, which surround the nucleus. The nucleus is very small compared to the atom as a whole, but it contains a majority of the atom’s

Grantham University 2 Color Changes 1. What three particles make up every atom? Protons, neutrons, and electrons are the three main subatomic particles found in an atom. Protons have a positive (+) charge. Neutrons have a zero charge and electrons have -1 charge. The neutron and proton make up the nucleus, the center of the atom and the electron surround the nucleus. Protons are positively charged; reside in the center of the atom called the nucleus. Electrons are negatively

Chemistry 1. 5 points of the particle theory: * 1. All matter is made up of tiny particle with empty spaces between them * 2. Different substances are made up of different particles * 3. Particle are always in constant random motion * 4. Particles of a substance move faster as the temperature increases * 5. Particles attract each other 2. Changing state from solid to liquid to gas: * form a solid when the forces are strong enough to form a rigid shape * they gain

* What does that mean? * Theory: Explanation * Atomic: Of atoms * How did we develop this theory? * Began with the Greeks * Democritus- 470-380 B.C. * Matter cannot be broken down indefinitely. At some point you end up with a piece that cannot be divided. That smallest piece he called an atom, from the Greek word atomos, which means “indivisible” * All matter is composed of atoms, which are bits of matter too small to be seen. These atoms

center core of the atom. There are two parts of a nucleus and they consist of protons and neutrons. Protons contain a positive charge and neutrons contain no charge at all. Atoms of the same element have the same number of protons. The remainder of the atom is made up of an electron field. Electrons are negatively charged particles and they whirl around the nucleus at a great speed. The number of electrons and protons are equal. 2) Describe metallic bonding. Metallic atoms have only a few
