Compare and Contrast Of The Elements
Helium and Oxygen are two chemical elements in the periodic table
though a significant difference can be observed between them based on
their chemical properties. They are both gases at room temperature; but,
Helium is a chemically inert noble gas. The chemical properties of these two elements are completely different from each other. For example; Oxygen quickly reacts with many elements and compounds, while Helium does not react with any. This can be identified as the key difference
between Helium and Oxygen. However, the inert behavior of helium has so
many commercial applications, and also Oxygen is one of the most
invaluable gas for both human and animals.
What is Helium?
Helium is the second most abundant element in the universe, and it is the second lightest element in the periodic table. It is a tasteless, odorless and colourless monatomic gas at room temperature with a low boiling point. Helium is the first member of the noble gas family, and it is the least reactive element. It has only two electrons
that are strongly attracted to the nucleus. Large quantities of Helium
are naturally produced in energy-producing fusion reactions in stars.
The radioactive decay of minerals also produces helium. In addition, natural gas deposits also contain the helium gas.
Helium possesses some unusual
properties; it becomes a superfluid at very low temperatures. A
superfluid can flow upward against the gravity.
Helium has the lowest melting point out of all the other elements. It
is the only element that cannot be solidified by lowering the
temperature.
What is Oxygen?
Oxygen is a member of chalcogen group (group VI A) in the periodic table. It is a diatomic,
highly reactive, colourless, odourless gas. Oxygen is the third most
abundant element in the universe by mass. In most chemical reactions;
Oxygen acts as an oxidizing agent, but it can also reduce some chemical compounds. Oxygen has two types of allotropes; dioxygen (O2) and trioxygen (O3), which is called ozone.
Properties of Helium and Oxygen:
Reactivity:
Helium:
Helium is an inert gas; it is the least
reactive element in the noble gas family. In other words, Helium is
completely inert, it does not react with any other element.
Oxygen:
Compared to Helium, the chemical
reactivity of Oxygen is extremely high. Even though it is a di-molecular
stable gas at room temperature, it quickly reacts with so many elements
and compounds. However, Oxygen does not react with itself, Nitrogen,
acids, bases and water under normal conditions. Oxygen can act as both
oxidizing agent and reducing agent; therefore it shows so many chemical
reactions. It has the second highest electronegativity value (next to fluorine) from other reactive elements. The solubility of oxygen in water depends on the temperature.
Oxidation States:
Helium:Helium does not show multiple oxidation states. It has only one oxidation state; it is zero.
Oxygen:
The most common oxidation state of Oxygen is -2. But, it is capable of having oxidation states of -2, -1, -1/2, 0, +1, and +2.
Isotopes:
Helium:
There are two types of naturally occurring Helium isotopes; Helium 3 (3He) and Helium 4 (4He). The relative abundance of 3He is very low compared to 4He. Three radioactive isotopes of Helium have been made, but they don’t have any commercial applications.
Oxygen:
Oxygen has four isotopes, but only three isotopes are stable; they are 16O, 17O and18O. The most abundant type is 16O, which makes about 99.762%.
Applications:
Helium:
The chemically inert behavior of Helium
has a numerous number of applications. It is used in low-temperature
research in cooling systems, as a fuel source in rockets, in the welding
process, in Lead detection systems, to fill balloons and to prevent
objects from reacting with Oxygen.
Oxygen:
Oxygen has many uses in our daily lives,
starting from respiration; humans and animals can’t live without
oxygen. Some other examples include; to produce medicines, acids, in
combustion, purification of water, welding and melting metals.

What the function of H 3 and H 4?
BalasHapusH3 is the the isotopes of H1 and called triton,H4 ? what is that ? ,i only know He4. Thanks.
HapusPlease explain what is the function of helium in daily life?
BalasHapusto fill up the air ballon.Hydrogen and oxygen are often used as rocket fuel. Helium-neon lasers use the element extensively. These instruments are used for barcode reading. The same element is needed to monitor small fractures in ships and other vehicles

BalasHapusWhat are the things that can increase oxygen levels in the blood?
What are the things that can increase oxygen levels in the blood?
HapusHealthy air
Regular exercise
lose weight
Enough sleep time
Why helium can make a strange sound, what properties helium possesses ?
BalasHapusAs is known, in the human throat there is a vocal cords. When we speak, actually what happens is we push the air out of the chest cavity so that it passes the vocal cords. The air impulse makes the vocal cords vibrate. This vibration of the vocal cords cause sounds. So finally to the eardrum of the listener. This is the origin of sound that we produce every day
HapusHelium is a chemical element belonging to a group of noble gases in the periodic table of elements. This gas is colorless, odorless, non-toxic, and many other properties. The nature of helium gas which is the key ingredient in the explanation of the phenomenon of sound humor when we inhale it is that helium gas has a small density.
Why He does not react with any other element?
BalasHapusHelium and oxygen are elements that can easily react with almost all of its other elements

BalasHapusWhat are the benefits of oxygen in industry?
Hapus1. Helping Combustion
If you want to burn but the absence of oxygen, then burning will not be. Because in reality, combustion conditions must have three important components, namely heat sources, fuel and oxygen. So fire is not just because of the source of fire and fuel but also because there is oxygen.
Ironically, however, the benefits of oxygen are misused in forest burning, which destroys oxygen levels that interfere with the surrounding environment.
2. Fly the plane
The aircraft is only capable of flying with a maximum height of 11 km. This is because the higher the flight, the more it will decrease the oxygen levels in the air.
3, Utilized rocket spacecraft
The oxygen in the atmosphere is used by rockets for fuel that produce a thrust force so that rockets can move, either forward or bolted upward.
4. As Explosives
Oxygen reacted with various other elements can be explosive.
5. Required for welding
The oxygen benefits used simultaneously with acitilene gas are used for welding.
6. To dive
No humans can dive long in the water without a dive tool. Because humans used to breathe with oxygen using a tube.
