Molybdenum Chemical Properties Atomic Structure and Uses

Molybdenum is an essential mineral and chemical element. Molybdenum in the periodic table stands at 42nd atomic number. In 1778, Carl Wilhelm Scheele had found this element. The name of the element is derived from the Greek word, “Molybdos”. Molybdos defines lead in the Greek language. You can find this mineral in foods like cereal grains, milk, cheese, legumes, leafy vegetables, nuts, and organ meats.

The color of the Molybdenum is silvery white. It is the pure element with the highest melting point, and it is a hard transition metal. Acids can attack the part slowly. Molybdenum is useful for the protein breakdown in the body, and deficiency of this mineral is uncommon. Well, Molybdenum is used for cancer of the esophagus and Wilson diseases, but no positive evidence is found for the same.

Furthermore, you will be surprised with the information about Molybdenum atomic number and various isotopes ranging from 83 - 117. It has nearly 35 isotopes. Mo and Mo2+4 are the symbols and the chemical formula of mineral Molybdenum, respectively.

Molybdenum in Periodic Table and Electronic Configuration 

Electronic Configuration of Molybdenum

When you know the basic rules for electron configuration of the element while studying the atomic table, you can find any element’s electron configuration easily. The electron configuration of Molybdenum is not different from that. When you notice the Molybdenum in the periodic table, you will find the atomic number of Molybdenum that is 42

According to rules,

• In the first orbit: 2 electrons

• In the second orbit: 8 electrons

• In the third orbit: 18 electrons

• In the fourth orbit: 13 electrons

• In the fifth orbit: 1 electron.

Or we can say, 1s2 2s2p6 3s2p6d10 4s2p6d5 5s1 or

Kr

Kr4d55s1

Facts About Molybdenum

• It is the corrosion resistance and ductile mineral.

• It is an essential micronutrient for our body

• It forms many compounds by chemical reaction with other elements easily.

• You can not find the free form of this element in nature.

• It contains the 1.2 ppm (parts per million) of the earth crust.

• Molybdenum disulfide (molybdenite) is the Molybdenum ore and can be found in powellite (calcium molybdate) and wulfenite (lead molybdate).

• It can be obtained while tungsten mining or copper mining.

• According to RSC (Royal Society Of Chemistry), it is produced 200,000 tons every year worldwide.

• From the crust of the earth, it is the 54th common mineral that is found.

• A soft and black mineral that is called Molybdenum or Molybdenite was used in pencils in ancient times.

• Nitrogenous enzymes are essential enzymes that contain this mineral and are helpful in proper utilization and systemization of protein.

Abundance of Molybdenum

• Seawater/p.p.m.: 0.01

• Earth's Crust/p.p.m.: 1.5

• Atmosphere/p.p.m.: N/A

• Sun (Relative to H=1E12): 145

Molybdenum Uses

It has better strength at a higher temperature, and so it is a better alloying agent. In the manufacturing of steel material, this element is used to increase the strength of steel. Furthermore, it is also applicable in the engines’ production.

Deficiency of Molybdenum is uncommon, but doctors advise to have cauliflower in the diet to maintain the level of the mineral in our body. Cauliflower is a source of Molybdenum because fertilizers used for such plants have plenty of Molybdenum minerals.

In the petroleum industry, the Mo mineral is used as a catalyst agent.

Health Effects of Molybdenum

Well, it is said that an excess amount of Molybdenum is toxic and even some of the Molybdenum compounds are highly toxic. Some animal experiments have proved the poisonous nature of Mo and Mo compounds. Workers working in the Soviet Mo-Cu plant had recorded the liver dysfunction health issue. Furthermore, some workers had seen gout signs. People living in Armenia also notice the gout signs because Armenia is a Mo-rich landscape. Some of the health issues were recorded like hands, feet, joints, erythema, articular deformities, and knee pains.

Environmental Effects of Molybdenum

All the species need Mo minerals in an adequate amount like other trace minerals. It would severely affect the intake of large doses or excess amounts of Mo mineral. Fetal deformities can arise because of the toxic effect of excess Molybdenum. Furthermore, fodder should have less than ten ppm of Mo mineral.

Touring with Chrome Molybdenum Bike Frame

Nowadays, touring also has become a part of life. The pandemic has made people mentally stressed, willing to let people wander to the natural heartwarming places. And Chromoly used in the bike frame will be one of the best recommendations to be given in the times near the celebration towards the new year. There are so many reasons behind this. And they are pointed below:

• Just like an aluminium frame, when subjected to any wear and tear the chrome-Molybdenum bike frame won’t let you fail. It is because the material property is strong enough to resist them. Especially when it comes to touring, the bikes are vulnerable to major and minor hits. So having one of these along, will safeguard the bike body and also the one who drives it.

• The damping nature of the frame helps the one who’s involved in touring much more comfortable. When compared to the usual Al frame, this is a lot smoother. Since the chrome-Molybdenum frames are harsher.

• Also, there are spaces where you can carry your bags and pieces of stuff. This is possible by the thin tubes and ease of threading within them.

• When in need of repair it is very easy. Since it can be welded more easily. However, this is not the case for Al frames.

• Though the bike frames of Chromoly are expensive. It is cheaper when compared to the titanium or Carbon ones. 

While praising the benefits of Molybdenum, students must be aware of the harmful side effects as well. Over-concentration leads to toxicity. It has already been reported that a man tried to consume it for about 18 days continuously. And it resulted from him having seizures, hallucinations and other health problems. So while trying to take the benefits out, you must always remember how much dose is the limit. 

The extra knowledge students acquire will not only help them in academics but also in real-life while confronting the situation. And Vedantu website and its apps have helped a lot in this case. They have developed a system where the students are learning not just for their academics but also for applying in real life. And hence, this will help them crack future competitive exams too.
