Why is it not possible to turn lead into gold?

Upvote11 Downvote3

Changing the element requires changing the atomic (proton) number. The number of protons cannot be altered by any chemical means. Because lead is stable, forcing it to release three protons requires a vast input of energy, such that the cost of transmuting it greatly surpasses the value of the resulting gold.

Furthermore, how did alchemists try to make gold?

The supposedly dense, waxy, red material was said to enable the process that has become synonymous with alchemy—chrysopoeia, the metamorphosis, or transmutation, of base metals such as lead into gold.

Can we artificially make gold?

Yes, gold can be created from other elements. But the process requires nuclear reactions, and is so expensive that you currently cannot make money by selling the gold that you create from other elements. All regular matter is made out of atoms. Gold is the chemical element with 79 protons in each atomic nucleus.

Can you make artificial gold?

Gold can currently be manufactured in a nuclear reactor by irradiation either of platinum or mercury. Only the mercury isotope 196Hg, which occurs with a frequency of 0.15% in natural mercury, can be converted to gold by slow neutron capture, and following electron capture, decay into gold's only stable isotope, 197Au.

How do you turn a penny gold?

To turn the penny silver

Fill the small 50 mL beaker with 3/4 full tap water.
Dissolve 30 grams of Zinc Sulfate in 100 mL of water in the 250 mL beaker.
Place mossy zinc pieces in the beaker with the zinc sulfate solution, enough pieces to almost cover beaker bottom.

What happens in a nuclear decay?

When the nucleus of an atom possesses either too many or too few neutrons compared to the number of protons it becomes unstable. Unstable nuclei split up in a process called radioactive decay and emit radioactive radiation. You need to know the effect of alpha and beta decay on the nucleus.

3

Why mass defect is so important?

Nuclear binding energy is used to determine whether fission or fusion will be a favorable process. The mass defect of a nucleus represents the mass of the energy binding the nucleus, and is the difference between the mass of a nucleus and the sum of the masses of the nucleons of which it is composed.

4

What is the definition of mass defect?

In physics and chemistry, a mass defect refers to the difference in mass between of an atom and the sum of the masses of the protons, neutrons, and electrons of the atom. The "missing" mass is the energy released by the formation of the atomic nucleus.

5

What type of alloy is a gold penny?

When the zinc-coated penny is heated, the penny becomes gold in color. The gold color is due to the zinc migrating through the copper to convert to the alpha-form of brass alloy which has a zinc content of less than 35%. This form of the brass alloy is a golden color.

6

What nuclear emission has the greatest penetrating power?

Beta rays have a greater penetrating power than Alpha rays and can penetrate 3mm of aluminum. Gamma Radiation and x-rays are high-energy electromagnetic radiation (high energy photons). This classification of radiation has the greatest penetrating power.

7

What is radioactive decay and what does it do?

Radioactive decay is the spontaneous breakdown of an atomic nucleus resulting in the release of energy and matter from the nucleus. Remember that a radioisotope has unstable nuclei that does not have enough binding energy to hold the nucleus together.

8

Why is radioactive decay said to be random?

Radioactive decay is the set of various processes by which unstable atomic nuclei (nuclides) emit subatomic particles (radiation). Decay is said to occur in the parent nucleus and produces a daughter nucleus. This is a random process, i.e. it is impossible to predict the decay of individual atoms.

13

Can you turn any metal into gold?

It transpired that, under true nuclear transmutation, it is far easier to turn gold into lead than the reverse reaction, which was the one the alchemists had ardently pursued. Nuclear experiments have successfully transmuted lead into gold, but the expense far exceeds any gain.

14

Can you make gold out of mercury?

Only the mercury isotope ¹⁹⁶Hg, which occurs with a frequency of 0.15% in natural mercury, can be converted to gold by slow neutron capture, and following electron capture, decay into gold's only stable isotope, ¹⁹⁷Au. However such high-energy neutrons can be produced only by particle accelerators..

15

How the gold is created?

Gold is thought to have been produced in supernova nucleosynthesis, and from the collision of neutron stars, and to have been present in the dust from which the Solar System formed. Because the Earth was molten when it was formed, almost all of the gold present in the early Earth probably sank into the planetary core.

16

What happens during the process of nuclear fission?

The process of splitting a nucleus is called nuclear fission. Uranium or plutonium isotopes are normally used as the fuel in nuclear reactors, because their atoms have relatively large nuclei that are easy to split, especially when hit by neutrons. the nucleus splits into two smaller nuclei, which are radioactive.

17

What color is the philosopher's stone?

Some ancient and medieval alchemical texts leave clues to the physical appearance of the stone of the philosophers, specifically the red stone. It is often said to be orange (saffron colored) or red when ground to powder. Or in a solid form, an intermediate between red and purple, transparent and glass-like.

18

What happens in the process of nuclear fusion?

It gets squeeze together so tightly that four hydrogen nuclei combine to form one helium atom. This is called nuclear fusion. In the process some of the mass of the hydrogen atoms is converted into energy in the form of light. The same process occurs in thermonuclear (fusion) bombs.

19

What half life is?

the time required for one half the atoms of a given amount of a radioactive substance to disintegrate. Also called biological half-life. Pharmacology. the time required for the activity of a substance taken into the body to lose one half its initial effectiveness.

20

When alchemy was invented?

As previously stated above, Chinese alchemy was more related to medicine. It is said that the Chinese invented gunpowder while trying to find a potion for eternal life. Described in 9th-century texts and used in fireworks in China by the 10th century, it was used in cannons by 1290.
