How many stable isotopes does CU have?

How many stable isotopes does CU have?

two stable isotopes

What are the stable isotopes of copper?

Copper (29Cu) has two stable isotopes, 63Cu and 65Cu, along with 27 radioisotopes. The most stable radioisotope is 67Cu with a half-life of 61.83 hours, while the least stable is 54Cu with a half-life of approximately 75 ns.

How many neutrons are in the most common isotope of copper?

35 neutrons

How many neutrons are in a stable isotope?

For example, most carbon (≈ 99 %) has 6 protons and 6 neutrons and is written as 12C to reflect its atomic mass. However, about 1 % of the carbon in the Earth’s biosphere has 6 protons and 7 neutrons (13C) forming the heavy stable isotope of this important element. Stable isotopes do not decay into other elements.

Why is iron 56 the most stable nucleus?

This stability is caused by the attractive nuclear force between nucleons. Iron 56 is the most stable nucleus. It is most efficiently bound and has the lowest average mass per nucleon. It takes more energy per nucleon to take one of these nuclei completely apart than it takes for any other nucleus.

Is Coke the purest form of carbon?

Coke is almost pure form of carbon.

Which is the purest allotrope?

Diamond is the purest form of carbon. Different forms of the same chemical substance are called allotropes. Graphite and diamond are two major allotropes of carbon. Diamond is a form of carbon in which each carbon atom is covalently bonded to four other carbon atoms.

Is carbon monoxide called Coke?

At temperatures of 1000°C and above, coke carbon reacts with carbon dioxide to produce carbon monoxide, gasifying the coke in the process.

Why Coke is not used as a fuel?

Answer: because fuel has different properties than coke as fuel can help a car move and coke can’t do do that as it does not have the chemicals to complete that task …

Why is coca-cola called Coke?

When launched, Coca-Cola’s two key ingredients were cocaine and caffeine. The cocaine was derived from the coca leaf and the caffeine from kola nut (also spelled “cola nut” at the time), leading to the name Coca-Cola.

Is Coke is a clean fuel?

Coke is used as a fuel and as a reducing agent in smelting iron ore in a blast furnace. The carbon monoxide produced by its combustion reduces iron oxide (hematite) to the iron product. Although coke is more expensive than coal, it can be used in households as a clean fuel, relatively free of smoke and impurities.

Does Coke burn hotter than coal?

Coal is a shiny, black fossil fuel that contains impurities, emits smoke when burned, and produces less heat than coke. Coke is a dull, black byproduct of coal that burns hotter and cleaner.
