Humor in Chemistry
Bond formation can me unwell (Electrons join up in a shell) For it doesn't seem fine To say they combine When we know very well they repel! Limericks
Chemistry is full of rules Atoms, moles, and molecules. Some of which might fit together, Maybe now, and likely never. Limericks
O ONN He Ar Artie how come you &I can never find anyone compatible.
Take, Take, Take, that is all people in Halogens ever do. Na K Cl F Br I
If water is made up of hydrogen and oxygen why cant peole breath under water?

We had a lot of fun in Chemistry did you? Sidra Jalil Zara Babar Saba Tariq Maryam Ahmad
Covalent Bonding Illustration of the formation of the Covalent bond between Hydrogen and Chlorine HCl.
Chemistry of Life. All matter is made up of atoms. Matter is anything that has mass and takes up space.
Counting Atoms Obviously, there are more materials in the world than just 100 or so elements on the periodic table.
The Atom - Atoms react or not depending on its electron structure. - All atoms desire to have a full outer electron shell. - Metals will lose e - and nonmetals.
Atoms, Elements, & Compounds. Elements Element --- any substance that can’t be broken down into simpler substances. Example of an element --- Oxygen,
CHEMICAL BONDS. CHEMICAL BONDING I Constructing Molecular Models What limited the number of “atoms” you could connect? Black – 4, Red – 2, White - 1.
What causes reactivity of elements All atoms want to have a completely full valence shell (normally 8 electrons). For the moment we will only concentrate.
Unit 1 Lesson 1 The Chemistry of Biology. Proton, Electron, and Neutron Proton – _______________________that make up part of the _____________ of an atom.
The Chemistry of Life Or Biochemistry Atoms, Molecules, Compounds, Chemical Bonds.
Focus on Valence Electrons: Draw valence for Na and Cl: NaCl What will happen when the two elements are combined? Na will transfer 1 electron to Cl Now,
Covalent Bonding. Consider the Chlorine A single, neutral chlorine atom has 7 valence electrons: [Ne]3s 2 3p 5 As a Lewis Structure (aka, just an element.
Bonding. Bonds Atoms of different elements may join together in a number of ways.
Each hydrogen molecule comprises two hydrogen atoms joined by a covalent bond.
Lesson: Atoms. Science Differentiation in action Elements are made up of one type of atom. Gold nuggets are made up of gold atoms. A sheet of copper is.
Chapter 3 – Atomic Structure. Elements Ionic Bonding Positively charged sodium is attracted to negatively charged chlorine to form sodium chloride (table.
Chemistry Unit 4 Bonding Why do atoms bond? -to become more stable -a full valence shell of electrons -valence shell = outside shell How do atoms bond?
Chemistry Calculations. Learning Intentions 1)How can we work out the formula mass of a chemical? 2)What is a mole? 3)How can we use formula mass and.
Aim: What are the basic concepts that you need to know about chemistry?
Matter: Anything that has mass and takes up space, or volume.
Covalent Bonding Occurs when atoms share electrons Different from ionic bonding Ionic Bond = Atoms completely transfer electrons Covalent bonding occurs.
Bell Work 1.Draw Hund’s Rule for: 1.Li 2.O 3.F 2.Write the Electron Configuration for 1.He 2.Be 3.S 4.Zn 3.What does the Aufbau Principle say? 4.PRE-AP.
An atom is the basic unit of matter (make up elements) If you break it any smaller it is no longer the element Atoms are made up of smaller pieces.
Chemical Bonding. Bonds between atoms are caused by electrons in outermost shells The process of bond formation is called a reaction.
Bonding Making Molecules and Compounds. What’s the difference between a molecule and a compound? All compounds are molecules, but not all molecules are.
ELEMENTS Remember: Atoms of one type form an element –A bunch of gold atoms form gold…etc. Elements are the simplest form of a substance Every element.
The Periodic Table. Why is the Periodic Table important to me? The periodic table is the most useful tool to a chemist. You get to use it on every.
Chemistry of Life. Matter is anything that has _______ and takes up ________. mass space rocks soil water bear air trees.
Lecture 1.1 Refresh your high school chemistry CS882, Fall 2006.
Hybridization: Localized Electron Model. Why Hybridization Occurs Example: Methane (CH 4 ) 4 hydrogens bonded to the central carbon atom The 4 electrons.
Objective: To describe how atoms bond together to form compounds using valence electrons Journal: ◦ How many protons, neutrons and electrons are in.
PS.2b Compounds. Compounds are made of 2 or more kinds of atoms which combine in a specific ratio.
Year 10 SCIENCE Chemistry Bonding. Bonding Basics Why do atoms bond together? We use a concept called "Happy Atoms." We figure that most atoms want to.
Unit 1 Lesson 1 The Chemistry of Biology. Proton, Electron, and Neutron Proton – positive particles that make up part of the nucleus of an atom Neutron.
ATOMS ELEMENTS PERIODIC TABLE MOLECULES COMPOUNDS.
The CHEMISTRY of Life CHEMISTRY is the foundation of BIOLOGY.
The Chemical Basis of Life. Objectives: Explain the relationship between elements, compounds, atoms, and molecules List the major elements and major minerals.
BASIC CHEMISTRY. An understanding of an atom’s structure is required to understand how chemical bonds form. The atom is the basic building block of all.
Compounds and Formulas Matter, elements, and such.
Stability in Bonding. A chemical formula tells us what elements are contained in a compound, and the exact number of atoms there are in a unit of that.
Ch. 2: “Chemistry of Life” Directed Reading: “Nature of Matter”
Basic Chemistry CHAPTER 2-2. Inert Elements Atoms are stable (inert) when the outermost shell is complete.
Compounds Chapter 3.1 A molecule is a group of atoms in which the atoms are bond together by 1 or more pairs of electrons.
CHEMISTRY!!! Yeah baby!. Structure of the Atom Nucleus: The center of an atom. Holds the protons and neutrons.
Chapter 2: Molecules & Solutions. What is a molecule? two or more bonded Definition: a molecule is a group of two or more chemically bonded atoms. The.
What is oxidation number? What do those little +1, +2, -1, -2, etc. numbers mean?
One mole of any substance is 6.02 x particles of that substance (this is named in honor of Amadeo Avogadro, thus is called “Avogadro’s number”) You’ll.
Reactions of group 1 metals with oxygen The group 1 metals all react in a similar way because ……….
Organic Compounds 11.2 The Tetrahedral Structure of Carbon 11.3 Polarity of Organic Molecules Chapter 11 Introduction to Organic Chemistry.
Bonding Why do atoms bond? The octet rule – all atoms bond so they have 8 electrons in their outer shell, so that it is FULL.
