Atomic Structure The discovery of atoms began with Democritus, a Greek philosopher, who was the first person to suggest that atoms exist. However Democritus made the false claim that atoms were indestructible which was proven wrong with the development of the atomic bomb (nuclear power), additionally he did not support his idea with scientific evidence or explain the chemical behavior of the atom. Following Democritus was Dalton who took the idea of the atom and explained it and supported it with scientific methods. Atom= The smallest particle of an element that retains its identity within chemical reactions due to maintaining chemical and physical properties. Dalton?s Atomic Theory: All elements are composed of indivisible particles called atoms (later disproved)

Chapter 2 Key Terms acidity Ions are also important for measuring a substance?s acidity in a water solution, a chemical characteristic that helps determine how a substance dissolved in water will interact with and affect its environment. atom The most basic building block of matter is an atom: the smallest unit of matter into which an element can be divided and still retain its chemical properties. atomic number Each element has a unique atomic number, equal to the number of protons in the nucleus of its atom. atomic theory The idea that all elements are made up of atoms is called the atomic theory and is the most widely accepted scientific theory in chemistry. cells

Atomic Structure Definitions ? Acceleration ? The stage of mass spectrometry during which the movement of the ions of the sample is speeded up using a series of negatively-charged plates. ? Atomic number ? The number of protons in the nucleus of an atom of an element. Represented by the symbol Z. Also called the proton number. ? Deflection ? The stage of mass spectrometry during which the beam of ions is bent by a particular amount, depending on its mass-to-charge ratio. This is achieved using an electromagnet. ? Detection ? The stage of mass spectrometry during which the ions strike a collector plate, producing a mass spectrum for analysis. ? Diatomic ? A molecule consisting of two atoms. ? Electromagnet ? The part of a mass spectrometer responsible for the

Chapter 6-Chemistry in Biology COMPOSITION OF MATTER -Matter-everything in universe is composed of matter. -Matter is anything that occupies space or has mass -Mass-quantity of matter in an object -Weight-pull of gravity on us ELEMENTS -Pure substances that cannot be broken down chemically into simpler kinds of matter -More than 100 elements (92 naturally occuring) -90% of the mass of an organism is composed of 4 elements (oxygen, carbon, hydrogen, and nitrogen) -Each element has a unique chemical symbol -Consists of 1-2 letters -First letter is always captialized ATOMS -The simplest particle of an elemetnt that remains all the properties of that element. -Properties of atoms determine the structure and properties of the matter they compose.

Useful Element Notations The number of protons in the nucleus Determines the identity of the atom (which element it is) Atomic Number (Z) If you change the number of protons, the atom changes to another element. The total number of particles in the nucleus?protons and neutrons The total number of particles that make up the mass of the atom Mass Number (A) Atoms of an element which have various amounts of neutrons but the same number of protons Isotopes: Since the number of neutrons changes, the mass of the isotopes is different. Count Those Neutrons It shows the mass number, atomic number, and symbol for the element. Isotopic Notation X A Z Isotopic Notation Example: Be 9 9 protons and neutrons 9 4 4 4 protons Therefore, there must be 5 neutrons. 18 40 22 58 Question

Democritus Greek; said that everything in the universe starts with small pieces of un-cuttable (atomos) pieces of matter but had no proof ? Aristotle Greek; said there was no such thing as the smallest piece of matter; he was the good speaker therefore people of his time believed him John Dalton created the Atomic Theory in the 1800's The Atomic Theory says that all things in the world are made of atoms, and if the materials are the same, the atoms are identical especially in their mass; different elements have different atoms and a chemical reaction is a rearrangement of atoms William Crookes
