Hydrogen was produced in metallic form in which year?
Harvard University’s Ranga Dias and Isaac F. Silvera claimed that there is experimental evidence of the synthesis of metallic hydrogen in laboratory under controlled conditions. The claims were released on 5th October 2016. Metallic hydrogen was predicted was back in 1935 by Hillard Bell Huntington and Eugene Wigner.
Which element is used as a treatment for mood disorders?
Lithium, the lightest of all the metals, promotes biochemical and molecular effects which affect neurotransmitters, hormones etc. Doctors don’t exactly know how it works. Lithium has been used for more than 60 years now and is still one of the reliable methods to reduce severity in many mood disorders.
Which one of the following is the symbol of Boron?
B is the symbol of Boron.
Which is the most abundant element in our universe?
Hydrogen is the most abundant element in our universe. It is the most abundant because of its simplest form (1 proton, 1 electron and 0 neutron). 90% of the visible universe is made up of hydrogen.
Which of the elements is sweet but hazardous for health?
Beryllium compounds are sweet but are toxic and can even cause cancers. Beryllium compounds once ingested or inhaled cannot be seen by our immune system which makes tracing pretty difficult.
Helium belongs to which family?
Helium belongs to the family of Noble gases. The other gases in the family of noble gases are Neon, Argon, Krypton, Xenon, and Radon. These gases are also known as rare gases or inert gases.
Which element is considered as one of the key elements to the evolution of life on Earth?
Boron helps in stabilizing ribosomes, a part of ribonucleic acid (RNA) and hence is considered as a key element to the evolution of life on earth.
Which element has atomic number 1 and mass number 1?
Hydrogen is the first element in periodic table and hence has atomic number 1. Its mass number is 1 because it has no neutrons and hence the mass number is one. Number of neutrons = Mass number – atomic number 0 = Mass number – 1 Mass number = 1.
Which is the third element which is created in the Big Bang?
Lithium is the third element that was produced in Big Bang. The first two were Hydrogen and Helium. Small amounts of Lithium were produced.
What would be the mass number of an element, the atom of which contains 2 neutrons, 2 electrons and 2 protons?
The element is Helium. Since it has 2 protons and 2 electrons, the atomic number is 2. Now that we know the number of neutrons and atomic number, we can use the formula to find mass number. Number of neutrons = Mass number – atomic number; 2 = Mass number – 2; therefore, Mass number = 2+2. Mass number = 4.
Which one of the elements is used as a coolant in Large Hadron Collider and in MRI scanners?
Helium is used as a coolant in Large Hadron Collider and Magnetic Resonance Imaging scanners because it is highly unreactive. Helium is used in liquid form.
Which of the following is the symbol of Lithium?
Li is the symbol of Lithium.
Which element is extremely essential to plants?
Boron helps in formation of cell wall, maintaining the functional and structural integrity of biological membranes. It helps in energy movement in the plants. Boron deficiency leads to death of meristem, reduced fertility etc.
Which element was earlier known as Glyceynum after Glykis (a Greek word) meaning sweet?
Beryllium was earlier known as Glyceynum because the taste of Beryllium is sweet. It was later changed so as to avoid confusion with a plant genus called glucine. Beryllium became the official name of the element in 1957.
Which of the elements is used by NASA as a rocket fuel to deliver crew to the space?
NASA uses liquid hydrogen as rock fuel to deliver crew to the space because it is light weight and for the amount of energy it gives. Also it is optimum for high-power applications.
Louis Nicolas Vauquelin, a French chemist, discovered which one of the elements?
Louis Nicolas Vauquelin discovered beryllium in the form of oxide in beryl and emerald, a green colored variety of beryl. He discovered beryllium in the year 1798.
How much amount of Boron do we consume in our lifetime?
According to Royal Society of Chemistry, humans consume around 60 grams of Boron from our food in our lifetime.
Which one of the elements was a key ingredient of 7 UP?
7-UP’s earlier name was Bib-Label Lithiated Lemon-Lime Soda and it contained Lithium citrate
Which element was used as the main ingredient in the mirrors that are used in NASA’s James Webb Technology?
Beryllium is used in mirrors for James Webb Technology because it is light weight and strong for its weight. Beryllium is also a good conductor of electricity and heat. It is not magnetic as well. These are few of the reasons why Beryllium is used for James Webb Technology.
Which element when inhaled can change our voice temporarily?
Helium, when inhaled, make our voice higher. Helium doesn’t alter the pitch of our voice. Helium is not toxic but breathing helium can result in asphyxiation because of the deprivation of oxygen.
