THE PERIODIC TABLE
1.What kind of elements represent the periodic table?
2.Nonmetals
They are found on the top and right side of the periodic table. he nonmetals are poor at losing electrons, but they are good at gaining electrons.
3.Noble gases.
are found in the far right column of the periodic table. Sometimes these are included with the nonmetals because they are not metals. However their behavior and properties are different enough from the other nonmetals that we will consider them as a separate classification.They are poor at both losing and gaining electrons.
1.Metals
They are found in the red part of the periodic table, they are good at loosing electrons.
4.The metalloids
Those are an element whose properties are intermediate between those of metals and solid non-metals or semiconductors properties. The metalloids are so-so at losing electrons and so-so at gaining electrons.
3.Which elements are in the P.T and which one of them impact in the environment?
Chemicals can pass into the air, water or soil when they are manufactured, used or they are removed.
Some chemicals are more worrisome than others because they can
enter the food chain and accumulate or persist in the environment for many years.
The majority of waste of mineral processing wastes are toxic. The most dangerous chemicals found near these sites are: arsenic, lead, chromium, mercury and cadmium
environmental pollutants lead acid batteries
These batteries are composed of sulfuric acid and lead plaques
Some of the main pollutants are:
2.What’s the ozone layer and what’s the importance to protecting environment?
Why to protect it? An upset in the ozone balance can have serious consequences for life on Earth.
What is it?
Is the region of the upper atmosphere, between roughly 15 and 35 km above Earth’s surface, containing relatively high concentrations of ozone molecules
The "bad" tropospheric ozone is increasing in the air we breathe, and the "good" stratospheric ozone is decreasing in our protective ozone layer.
4.How would you compare the air quality of Bogotá before and now?
Also, according to the Town Hall, different facts like the meteorological conditions and the forest fires have produced a damage on the air quality.
According to an article of the newspaper El Tiempo, Bogotá, year after year passess through several periods of high pollution.
