Monday

0213BW    At sea level, air is only about 21 percent oxygen. P 332(78% of the atmosphere is made up of nitrogen and the other 1% is made up of several gases. Oxygen is toxic at high levels)
0213CW    Solid non-metals tend to be dull, brittle, and poor conductors of electric current. P 333 (carbon, nitrogen, phosphorus, hydrogen, and oxygen are all non-metals found in your body’s DNA. Some non-metals are poisonous and highly reactive.)
0213HW    When nonmetals and metals react electrons move from the metal atoms to the nonmetal atom. P 334

Tuesday

0214BW    The families containing nonmetals are the carbon family, the nitrogen family, the oxygen family, the halogen family, the noble gases, and hydrogen. P 335
0214CW    In nature, nitrogen exists as two nitrogen atoms bonded together to form a diatomic molecule. P 336
0214HW    Oxygen is a diatomic molecule that is reactive enough to combine with almost every other element. P 337

Wednesday

0215BW    Half Day Work-shop— student/ teacher conferences
0215CW    
0215HW 

Thursday  

0216BW    Halogen means “salt forming.” All of the halogens, including Fluorine and Chlorine, are extremely dangerous. P337
0216CW    Noble gases do not ordinarily form compounds because their atoms do not usually gain, lose, or share electrons. P 338
0216HW    Hydrogen makes up more than 90 percent of the atoms in the universe; however, only 1% of Earth’s crust, oceans, and atmosphere consist of hydrogen. P 338

Friday

0217BW    Metalloids have mixed properties of metals and nonmetals. They are brittle, hard, and somewhat reactive. P 339
0217CW    Complete “Assess Your Understanding” p 341 on “class work” paper. P 341
0217HW

02/02 Chapter 8 online test due to be completed by Saturday 02/04

Note: Tuesday 01/24 we had a test on Chapter 7... there was no bellwork, classwork, or homework on this date.

Important: At the end of each week work is due for bellwork, classwork, and homework. One sheet for bellwork; one sheet for classwork; one sheet for homework. Assignments need to be dated and all three sheets stapled together. I will deduct points for all work that does not follow this simple format.

Turn in work on time. Late work will receive only 50% credit unless you were absent, sick, or other valid excuse. Turn in work on time!
