What element has 23 protons 28 neutrons 20 electrons?

Vanadium has very colorful oxidation states, including purple, green, blue and yellow. In 1911, German chemist Martin Henze discovered vanadium in the blood cells of sea squirts. Vanadium atoms have 23 electrons, 28 neutrons and 23 protons.

What is the mass number of an atom that contains 23 protons 23 electrons and 28 neutrons?

Mass Number = # protons + # neutrons. Mass Number = 23 + 28 = 51. The element is vanadium.

What isotope has an atomic number of 23 and contains 28 neutrons?

Vanadium-51 is composed of 23 protons, 28 neutrons, and 23 electrons.

What is vanadium used for?

Vanadium alloys are used in nuclear reactors because of vanadium’s low neutron-absorbing properties. Vanadium(V) oxide is used as a pigment for ceramics and glass, as a catalyst and in producing superconducting magnets. Vanadium is essential to some species, including humans, although we need very little.

Why is vanadium so special?

Vanadium’s corrosion-resistant properties make it ideal for tubes and pipes manufactured to carry chemicals. Vanadium-titanium alloys have the best strength-to-weight ratio of any engineered material on earth. Less than one percent of vanadium and as little chromium makes steel shock and vibration resistant.

What is vanadium for kids?

Vanadium is a chemical element on the periodic table. Vanadium is a hard metal that is malleable with a silvery-grey color in its pure form. Vanadium is named after Vanadís (Freyja), the Scandinavian goddess of beauty and fertility.

What is the mass number of the atom if it contains 28 protons 28 electrons and 34 neutrons?

1 Answer. For mass number, you add (only) the protons and neutrons, so the answer here is 62.

What is the mass number of an atom that has 28 protons 28 electrons and 30 neutrons?

Answer and Explanation: An atom with 28 protons and 30 neutrons has an atomic number of 28 and a mass number of (30+28) = 58.

What element contains 28 protons?

What transition metal compound is used as a catalyst in the manufacture of sulfuric acid?

Vanadium(V) oxide
Vanadium(V) oxide, V 2O 5, is used as a catalyst in the production of sulfuric acid.

How common is chromium?

Chromium is the 21st or 22nd most abundant element in the Earth’s crust. It is present at a concentration of approximately 100 parts per million. Most chromium is obtained by mining the mineral chromite. Although it is rare, native chromium also exists.

What is the atomic number of an atom which contains 28 protons 28 electrons and?

For mass number, you add (only) the protons and neutrons, so the answer here is 62.

How many protons does an atom have if its mass number 23 and its atomic number is 11?

The mass number of an element tells us the number of protons AND neutrons in an atom (the two particles that have a measurable mass). Sodium has a mass number of 23amu. Since sodium has 11 protons, the number of neutrons must be 23 – 11 = 12 neutrons.

How many protons are present if an atom has a mass number of 23 and atomic number of 11?

How are oxidation of lower oxidation state of vanadium is prevented?

Air will rapidly oxidise the vanadium(II) ions – but so also will the hydrogen ions present in the solution! The vanadium(II) solution is only stable as long as you keep the air out, and in the presence of the zinc. The zinc is necessary to keep the vanadium reduced.

How abundant is vanadium?

The cosmic abundance of vanadium in the universe is 0.0001%, making the element nearly as common as copper or zinc.
