NITROGEN IS MORE IMPORTANT THAN YOU THINK INTRODUCTION: In this article, we discuss nitrogen its important properties, and some incidents that happened in the past with people and instruments that deal with nitrogen. So, let's start: LIQUID NITROGEN INCIDENT THAT KILLED THREE TECHNICIAN OF NASA: The First space shuttle mission was named STS-1, the first orbital mission of NASA. This mission is uniquely described in this article due to the incident in which three technicians died due to inhalation of excess nitrogen of nitrogen. IMPORTANCE OF NITROGEN: Nitrogen is a crucial element in the periodic table due to many important properties. Nitrogen is a non-toxic & colorless gas that occupies 78% of the atmosphere. HISTORY OF NITROGEN: In the past, scientists had different opinions about this gas. For example, some scientists think it was brunt air because no combination occur in the presence of this element. Some believe it is very toxic and has no life because the environment fil...
The Extraordinary Chemistry of Group 1 Element:
Chemistry is very useful in our daily lives because everything around us is a build-up of atoms and
these atoms compose themselves to build things that are very useful in technology which is why
understanding chemistry is very important in everything from science to technology.
Group 1elements:
Group 1 elements are elements that are very important in many industries and also in our daily lives.
The chemistry of these elements is also unique.
So, let's start:
Group 1 elements include lithium, sodium, potassium, rubidium, cesium, and francium. They all metals
and have the following properties:
1. These all are metals.
2. They are soft and reactive.
3. They are excellent conductor of heat and electricity.
4. They react vigorously with water and have low melting and boiling points.
5. They have low density.
6. They are included in s-block elements.
Group 1 Physical Properties:
In physical properties of Group 1 elements include:
1. Its softness:
The elements of group 1 are very soft. They are cut knife very easily. They are softer than other metals
in the periodic table.
The softness of group elements generally increases as go down in a group. So, that is why potassium is
much softer than lithium and so on as very goes down.
2. Low density:
The elements of group 1 have very low density. For example, lithium, sodium, and potassium are less
dense than water.
The density of group 1 elements increases as very go down in a group. The reason is that down
increases the atomic number and that is why density increases.
Lithium is the most lightweight and less dense as compared to metals in the periodic table.
3. Shiny Appearances:
When freshly cut appears shiny but then after some time darkens because of the oxidation process.
4. Low melting and boiling point:
These elements have generally low melting and boiling points. The element cesium has a melting point
of 28.5 degrees Celcius.
The melting and boiling point generally decreases as we go downward. This is because of the fact that
with an increase in atomic number metallic bonds between metals decrease why the melting and
boiling points generally decrease as we go down.
5. Good conductor:
They are good conductor of heat and electricity. Because of the presence of free electrons.
The conductivity increases as we go down in a group. Because of the increase of electrons and the
increase in shielding effect.
Lithium:
The most important use of lithium is in battery technology because of its small size and use as hydrogen
storage.
Lithium has huge potential in our daily lives as lithium-ion batteries have many limitations but these are
the best to store electricity and in the future, we see a better version of this battery that transform
humanity forever.
Sodium:
Sodium is a very important element not for the fact because table salt NaCl contains sodium but also
because of its use in caustic soda. Caustic soda is useful for washing purposes.
In countries like Canada after snow storms road cleaner trucks throw salt on the road when prevent it
from de-icing agents.
Sodium compounds are also used in the purification of water.
Potassium:
Potassium salts like potassium chloride and potassium citrate are used as a food flavoring. Potassium is
also used in agriculture to form fertilizers and in fire extinguishing in the form of potassium
bicarbonate.
You all know about carbon dating but Is you know about radiometric well it is a process by which the
age of rock and stone are identified in this process potassium is used.
Rubidium:
Rubidium is used in atomic clocks which is useful for accurate measuring of time. Rubidium is used in
gas sensory and also used in solar cells.
Conclusion:
elements in such a configuration that their properties are periodic and predicted. Group 1 has similar
properties but their application is innumerable and that is why they are useful in our daily lives.
Group 1 elements are very important chemicals for life, technology,, and humanity.
