The Structure of the Atom. The Building Block of Matter. Atoms are the smallest particles of an element that retains the chemical properties of that element. Parts: Nucleus – small region in the center of the atom. (+ charged protons, = charged neutrons)

Matter & The Atom. Matter. The term matter describes all of the physical substances around us: your table, your body, a pencil, water, and so forth. Matter. Anything that has mass and takes up space (has volume) Made up of different kinds of atoms. Matter.

The Periodic Table Review . Who is Mendeleev? How did Mendeleev organize the periodic table?. A. Dmitri Mendeleev. Dmitri Mendeleev (1869, Russian). Organized elements by increasing atomic mass . Predicted the existence of undiscovered elements. The Periodic Table . Who is Mosely?

The Atoms Family. The Atoms Family was created by Kathleen Crawford, 1994 Presentation developed by Tracy Trimpe , 2006, http://sciencespot.net/. Name: Patty Proton Description: Positive Favorite Activity: Hanging out at the Nucleus Arcade. Name: Nelda Neutron Description: Neutral

Alien Element. Clue. What did you learn ?. Bo, Wo, J, L. They are noble gases. Noble gases are in group 18. Bo, Wo, J, L. Wo has greatest atomic mass, Bo the least. The atomic mass of the elements increases as you move left to right and top to bottom on the Per. Table. Alien Element.

CHEMISTRY DEPARTMENT WAID ACADEMY. Standard Grade Topic 3. 15. Which of the elements shown is a liquid at room temperature?. Silicon. Bromine. Oxygen. Magnesium. 20. Which of the elements shown is not naturally occurring?. Astatine. Antimony. Rubidium. Gallium. 15.

Introduction to Atoms. Preview. Section 1 Development of the Atomic Theory Section 2 The Atom. Concept Mapping. Section 1 Development of the Atomic Theory. Bellringer.

SL Chemistry. Tuesday September 22nd 2015. Agenda. Begin Topic 2 - Atomic Structure. Atoms contain a positively charged dense nucleus composed of protons and neutrons (nucleons). Negatively charged electrons occupy the space outside the nucleus.

ATOMIC STRUCTURE. Atomic Structure. All matter is composed of atoms . Understanding the structure of atoms is critical to understanding the properties of matter. HISTORY OF THE ATOM. John Dalton. 1808.

CHAPTER 2: A tomic structure and interatomic bonding. ISSUES TO ADDRESS. • What promotes bonding?. • What types of bonds are there?. • What properties are dependent on bonding?. Atomic Structure. } 1.67 x 10 -27 kg. atom – electrons – 9.11 x 10 -31 kg  protons neutrons

Chemistry Comes Alive. Anatomy & Physiology. Basic Chemistry. Matter The “stuff” of the universe. Anything that occupies space and has mass. States of matter Solid Liquid Gas. Basic Chemistry. Energy

Acids & Bases What’s the difference???. What is an acid?. An acid is a solution that has an excess of H+ ions. It comes from the Latin word acidus that means "sharp" or "sour". The more H + ions, the more acidic the solution. Properties of an Acid. Tastes Sour Conduct Electricity

The Periodic Law. Periodic Table of Elements video. Development of the Periodic Table. Dmitri Mendeleev developed the first periodic table The periodic table is an arrangement of elements according to their chemical and physical properties. Mendeleev’s Periodic Table.

The Chemistry of Life. Counting Atoms. Three Subatomic Particles:. Atomic Number. The number of protons in an atom Unique for every element. Atoms are always electrically neutral. This means that protons always equal the electron. Silicon Nitrogen Zinc. 14 p & 14 e 7 p & 7 e

ISOTOPIC NOTATION isotopes are atoms with the same number of protons but different number of neutrons. A Z X A = mass number (the total number of protons + neutrons) Z = atomic number (the total number of protons) X = element symbol.
