(2nd Quarter) How Do Metals Differ from Nonmetals? Flashcards
Used to build various vehicles, machines, and tools. It is considered the most important metal
Iron
Used to make cellphones, laptops, and cameras. It is strong and light
Magnesium
Used in fertilizers and to supply oxygen to people inside submarines and spacecrafts
Potassium
Used in streetlights and gives fireworks their yellow color
Sodium
It is added to table salt to prevent goiter
Potassium Iodide
Used to build DNA molecules
Zinc
It is a constituent of hemoglobin, an oxygen-carrying molecule in red blood cells
Iron
It is involved in the synthesis of enzymes
Manganese and Copper
It is important in cell respiration
Oxygen
These comprises the amino acids which are the building blocks of all cells
Carbon, nitrogen, hydrogen, sulfur, and oxygen

28
It is scientifically known as “Erythrocyte” and is produced by bones
Red Blood Cells (RBC)
What does “Eryth” and “Cyte” mean?
Eryth = Blood Cyte = Cell
It is partnered with calcium, which is good for the bones
Magnesium
To quickly digest or helps with digestion
Enzyme
Creates proteins
Amino Acids
It is the most abundant gas in the Sun
Helium
Composition of Atmosphere
??% - Nitrogen
??% - Oxygen
?% - Other Gases (CO2)
78% - Nitrogen
21% - Oxygen
1% - Other Gases
Are mixtures of metal (combination of two or more metals)
ex. Bronze (copper+tin)
Alloys
Systematic arrangement of E based on their atomic numbers and properties
Periodic Table
Made from combined silicon and oxygen. It is the most abundant compound in the earth’s crust and is the building block of rock and soil
Silicon Dioxide (or silica)
A group of elements that are generally dull, brittle, and poor conductors of heat and electricity. May be solid (carbon and sulfer) liquid (bromine) or gas (oxygen and nitrogen) at room temperature. They are found in the right side of the periodic table, except for hydrogen
Nonmetals
Used in torches for welding and and for preventing hypoxia in patients suffering from asthma, bronchitis, pulmonary edema, and chronic obstructive pulmonary disease (COPD)
Oxygen
