Nucleus= the very small center core of an atom. Proton- a positively charged atomic particle, found in the atom’s nucleus 3) electron- a negatively charged atomic particle, found outside the atom’s nucleus. 4) neutron- an atomic particle with no charge, found inside the atom’s nucleus
1)Objective: I will learn about the different properties of elements on the periodic table. 2) Essential Question: How would I explain the properties of different elements on the periodic table 3) Warm-up: Create a circle web of the different models of atoms from 1808 to the present. P. 606-607 4) Vocabulary: atomic mass, atomic number, periodic table, isotope
1) Atomic mass number= appears below the chemical symbol of an element. Is always equal to the sum of protons and neutrons in an atom’s nucleus 2)Atomic number= appears above the chemical symbol of an element. Is equal to the number of protons in an atom’s nucleus 3) Periodic table= A chart of the elements showing the repeating pattern of their properties. 4) isotope= An atom with the same number of protons but a different number of neutrons from the most stable form of an element.
Vocabulary quiz Friday on the following 20 words: Matter, element, atom, nucleus, neutrons, protons, electrons, atomic number, atomic mass number, isotope, periodic table, periodic group, ductility, reactivity, corrosion, malleability, alloys, conductivity, magnetism, semiconductor
What information did Mendeleev use to find a pattern in the elements? When did Mendeleev notice a pattern? Why was Mendeleev able to predict the properties of elements that had not yet been discovered? What information about an element is given in each square of the periodic table?
Melting point, .density, color, atomic mass, and the number of chemical bonds it could form. 2) When he arranged the elements in order of increasing atomic mass 3) He noticed a repeating pattern of the elements 4) Atomic number, chemical symbol, name, atomic mass
5) From the information in each square, what do you know about the structure of the element? 6) What are the rows of the periodic table called? 7) How do the properties of the metals in a period change from left to right? 8) What are the columns in the periodic table called?
5) The number of protons and electrons and the average number of neutrons 6) periods 7) From highly reactive to very unreactive 8) groups. By looking at an element’s periodic group, you can find other elements with similar properties
1)Objective: I will learn about the different properties elements may have. 2) Essential Question: Can I evaluate the significance of the different properties of elements 3) Warm-up: How is the modern day periodic table different than the one created by Dmitri Mendeleev? 4) Vocabulary: ductility, malleability, conductivity, reactivity, magnetism
1) Malleability= the ability of an element to be rolled into thin sheets. 2) ductility= the ability of an element to be stretched into wire 3) conductivity= the ability of an element to transfer heat or electricity to another object. 4) reactivity= the ease and speed with which an element combines with other substances 5) magnetism= the ability of an element to attract other materials.
Questions on Notes Where would you look on the periodic table to find an element with properties similar to that of another element? 2) What four things are found in each square of the periodic table? 3) What five things did Dmitri Mendeleev use to find a pattern in the elements? 4) What are the horizontal rows of the periodic table called? 5) How do the properties of metals in a period change from left to right?

1)Objective: I will learn about the use of metals in everyday life. 2) Essential Question: How well can I identify the use of metals in everyday life? 3) Warm-up: Answer the Math Analyzing Data questions on page 621. 4) Vocabulary: corrosion, alloy, semiconductor, periodic group
corrosion= The gradual wearing away of a metal due to a chemical reaction. (example: rust) Alloy= the mixing of two elements one of which is a metal. (Example: alloy rims on cars) Semiconductor= An element that conducts current under certain conditions. Example: the use of silicon in cellphones and other electronics. Periodic group= the horizontal rows of the periodic table, arranged based on their similar properties. (example: by looking at an element’s periodic group, you can find other elements with similar properties)

Congratulations! You are about to have the grand opening for your first business. You have decided to open up a store of metals. It’s time to get to work so you can load the store full of customers for the grand opening. Think of the types of metals you will sell and what they might be useful for. You may refer to the list of metal objects you found in the scavenger hunt yesterday.
Steps for creating the store of metals Identify 5 metals your store will sell. Draw illustrations depicting what the metals you sell may be used for. 3) Come up with a name for your store of metals. Create a propaganda slogan to market your store to the public 4) Prepare a commercial to present to the class advertising your store.
