1. What are characteristics for: – Metal – Nonmetal – Metalloid

2. The Periodic Table is a useful way to arrange elements. The vertical columns are called groups. The horizontal rows are called periods. Elements in the same group have similar properties. Three quarters of the elements are metals. One quarter of the elements are non-metals.

5. Properties of Metals, Nonmetals, and Metalloids METALS NONMETALS METALLOIDS malleable, lustrous, ductile, good conductors of heat and electricity gases or brittle solids at room temperature, poor conductors of heat and electricity (insulators) (Semi-metals) dull, brittle, semi-conductors (used in computer chips)

6. Metals - Good conductors of electricity and heat - Ductile - Malleable - Lustrous - In chemical reactions, metals lose electrons to form positively charged ions - Vast majority of known elements are metals - All are solids except for mercury, which is a liquid at room temperature and pressure Metals, Nonmetals, and Semimetals Copyright © 2007 Pearson Benjamin Cummings.

7. Nonmetals - Poor conductors of heat and electricity - Not lustrous - Can be gases, liquids, or solids - Solid nonmetals are brittle - Tend to gain electrons in reactions with metals to form negatively charged ions - Share electrons in reactions with other nonmetals Semimetals - Exhibit properties intermediate between metals and nonmetals Metals, Nonmetals, and Semimetals Copyright © 2007 Pearson Benjamin Cummings.

8. Q5. Name a gas in group 7 that is in the same period as Aluminium. Q1. Name a metal in group 1 that is in the same period as Magnesium. Q2. Name a metal in group 2 that in the same period as Lithium. Q3. Name a non-metal in the same group as Nitrogen. Q4. Name a noble gas in the same period as Oxygen.

9. Chlorine Cl 2 Hydrogen chlorideHCl Methane CH 4 Carbon dioxide CO 2 Draw a line between the molecule and its name.

10. 1.How many atoms of Hydrogen in one molecule of Methane CH 4 ? 2. How many atoms of Nitrogen in one molecule of Lead nitrate Pb(NO 3 ) 2 ? 3. Sodium oxide has two atoms of sodium for every atom of oxygen. What is the formula for sodium oxide?

11. 4. Magnesium chloride has one atom of Magnesium for every two atoms of chlorine. What is the formula for Magnesium chloride? 5. How many atoms of Nitrogen in one molecule of Ammonia NH 3 ?

12. Objective: 1. Learn the scientific method for naming compounds. 2. There are three rules for naming compounds: the “ide” rule, the “ate” rule and the “same” rule.

13. Rule 1: When two elements combine the ending is usually ” ……………ide”. metal goes first Sodium Chloride Magnesium Oxide Iron Sulfide Na Cl Mg O Fe S

14. Rule 2: When three or more different elements combine and one of them is Oxygen, the ending will be “………ate”. metal goes first Copper Sulfate Calcium Carbonate Cu S O O O O Ca C O O O

15. Rule 3: When two identical elements combine, the name does not change. H 2 = Hydrogen F 2 = Fluorine N 2 = Nitrogen Cl 2 = Chlorine O 2 = Oxygen HH NN OO FF Cl
