What is atomic mass number?

The mass number (symbol A, from the German word Atomgewicht [atomic weight]), also called atomic mass number or nucleon number, is the total number of protons and neutrons (together known as nucleons) in an atomic nucleus. The mass number is different for each different isotope of a chemical element.

What are the colors of molybdenum?

Data Zone
Classification: Molybdenum is a transition metal
Color: silvery-white
Atomic weight: 95.94
State: solid
Melting point: 2623 oC, 2896 K

How do you find the mass number?

Together, the number of protons and the number of neutrons determine an element's mass number: mass number = protons + neutrons. If you want to calculate how many neutrons an atom has, you can simply subtract the number of protons, or atomic number, from the mass number.

What is the first basic metal on the periodic table?

The alkali metals consist of the chemical elements lithium (Li), sodium (Na), potassium (K), rubidium (Rb), caesium (Cs), and francium (Fr). Together with hydrogen they comprise group 1, which lies in the s-block of the periodic table.

What is the deficiency of molybdenum?

Molybdenum deficiency symptoms in most plants are associated with a build-up of nitrate in the affected plant part. This is a result of poor nitrate reductase activity. Symptoms include: pale leaves with interveinal and marginal chlorosis (yellowing) and necrosis (scald);

What state of matter is molybdenum?

The Atomic Number of this element is 42 and the Element Symbol is Mo. Elements can be classified based on their physical states (States of Matter) e.g. gas, solid or liquid. This element is a solid. Molybdenum is classified as a "Transition Metal" which are located in Groups 3 - 12 of the Periodic Table.

How do you find the electrons?

The number of electrons in a neutral atom is equal to the number of protons. The mass number of the atom (M) is equal to the sum of the number of protons and neutrons in the nucleus. The number of neutrons is equal to the difference between the mass number of the atom (M) and the atomic number (Z).

What is the formula for molybdenum?

Which is a chemical property?

A chemical property is a characteristic of a substance that may be observed when it participates in a chemical reaction. Examples of chemical properties include flammability, toxicity, chemical stability, and heat of combustion.

What is made out of molybdenum?

Molybdenum is pronounced as meh-LIB-deh-nem. Molybdenum has a high melting point and is used to make the electrodes of electrically heated glass furnaces. Some electrical filaments are also made from molybdenum. The metal is used to make some missile and aircraft parts and is used in the nuclear power industry.

Is molybdenum a heavy metal?

Molybdenum is a transition metal in Group 6 of the Periodic Table between chromium and tungsten. Although molybdenum is sometimes described as a 'heavy metal' its properties are very different from those of the typical heavy metals, mercury, thallium and lead. It is much less toxic than these and other heavy metals.

Is molybdenum a rare earth element?

Molybdenum is not found free in nature. A relatively rare element, it is about as abundant as tungsten, which it resembles. For molybdenum the chief ore is molybdenite—molybdenum disulfide, MoS2—but molybdates such as lead molybdate, PbMoO4 (wulfenite), and MgMoO4 are also found.

Is Molybdenum poisonous?

Molybdenum toxicity is rare and studies in humans are limited. However, in animals, very high levels have been linked to reduced growth, kidney failure, infertility and diarrhea ( 19 ). On rare occasions, molybdenum supplements have caused serious side effects in humans, even when the doses were well within the UL.

What reacts with molybdenum?

Molybdenum reacts directly with fluorine, F2, at room temperature, forming molybdenum(VI) fluoride, MoF6. Under controlled conditions, molybdenum reacts with chlorine, Cl2, forming molybdenum(V) chloride, MoCl5.

Why is molybdenum important to life?

Molybdenum is essential for human, animal and plant life. It is a cofactor for a number of enzymes that catalyze chemical transformations in the global carbon, nitrogen and sulfur cycles. Thus, molybdenum-dependent enzymes are not only required for human health, but also for the health of the entire ecosystem.
