Isotopes

Isotopes of the same element have the same number of protons. They will also have the same number of electrons in a neutral state. Where they differ is in the number of neutrons in the nucleus. The chemical properties of an element are almost entirely determined by its electron structure, since chemical bonds can be understood as the transfer or sharing of electrons. This means isotopes of the same element will behave in the same way chemically. They will form the same chemical compounds and be largely indistinguishable from their isotopic brethren.

Isotopes such as radioisotopes, which are 'compounds containing radioactive forms of atoms, can be introduced into the body for the purpose of imaging, evaluating organ function, or localizing disease or tumors.' Modern uses of isotopes that are useful to us are smoke detectors, irradiation in pest control, agriculture applications (radioactive tracers), medical uses, etc. mike was here Additional uses come from the process of nuclear fission. It is used in nuclear power plants and in atom bombs.

The nucleus contains both protons and neutrons. An element has a fixed number of protons but may exist with various numbers of neutrons. The sum of the protons and neutrons is the mass number. For example, helium exists as 3He(2 protons and one neutron) or as 4He (2 protons and 2 neutrons). The two forms of helium are called isotopes of helium. Isotopes of an element have the same chemical properties but different weights. Some elements have many isomers. Tin (Sn) has about 38 known isotopes.

isotopes are atoms of the same element, having same atomic number but different atomic masses due to the difference in the number of neutrons present
Isotopes are atoms that have differing numbers of neutrons, but the same number of protons.

The isotope notation for an element with atomic number 29 (Z=29) could be represented as follows: Cu-63 or Cu-65, where Cu is the chemical symbol for copper.

Al-26: half-life 730000.0 years
Al-27: stable
Al-28: half-life 2.3 minutes

pyro=fire

crazy=just maniac

Pyromaniac- a person with a mania for setting things on fire

Kleptomaniac-obsession who steals even small things

Nymphomaniac or Eretomaniac --excessive sexual desire

Animaniac- obsession about animals

Isotopes of a given element have the same number of protons but different numbers of neutrons, resulting in different atomic masses. This causes isotopes to have different physical properties, such as differing in stability and radioactive decay rates.

The simplest way to calculate percentage is to divide the given amount by the total amount and then multiplying the answer by 100 to get the percentage of the given amount with respect to the total amount.

The equation can be put up as follows:

(Given amount/ Total amount) x100

For example if John scores 60 out of 75 in mathematics we can find the percentage of his marks by dividing 60 by 75 which comes to be 0.8 and then multiplying it by 100 which gives us the percentage of his marks in math which is 80%.

(60/75) x 100 = 80%

When there are a number of given amounts (variables) and we have to find their individual percentages then we have to add the given amounts to determine the total amount after which by the above mentioned procedure we can easily find the individual percentages by dividing each given amount by the total amount and then multiplying it by 100.

Percentage questions are often worded in different ways like how much is x% of y (80% of 75). Using the above example we can find the answer by multiplying 75 by 80 and then dividing the amount by 100 to find the answer which is 60. To calculate percentage increase or decrease between two numbers just subtract the smaller number from the greater and then divide the answer by the original one and then multiply it by 100 to determine the percentage increase or decrease. For example to calculate the percentage increase from 20 to 30 we subtract 20 from 30 and then divide the number obtained which is 10 by the original number which is 20 and then multiply the obtained number which is 0.5 by 100 to get the percentage increase which is 50%.

protons and neutrons in its nucleus. The number of protons determines the element, while the number of neutrons can vary to create different isotopes of that element.

7. the first one is 1H, regular old hydrogen.

The second one is 2H, aka deuterium.

The third one is 3H, aka tritium. none is radioactive except 3H. now for the artificial ones.

The fourth one is 4H, It has been synthesised in the laboratory by bombarding tritium with fast-moving deuterium nuclei. The fifth one is 5H, The nucleus consists of a proton and four neutrons. It has been synthesised in the laboratory by bombarding tritium with fast-moving tritium nuclei.

The sixth one is 6H, it decays through triple neutron emission and has a half-life of 3×10−22 seconds. The seventh and final one is 7H. It consists of a proton and six neutrons. It was first synthesised in 2003 by a group of Russian, Japanese and French scientists at RIKEN's RI Beam Science Laboratory by bombarding hydrogen with 8He atoms. In the resulting reaction, the helium-8's neutrons were donated to the hydrogen's nucleus. Hydrogen-4, -5, -6, and -7 are all radioactive.

Zinc has 5 stable isotopes (64, 66, 67, 68, and 70), all of which are neutral atoms at standard temperature and pressure. Zinc has many more isotopes that are radioactive, but these too are usually neutral atoms.

Isotopes of an element have the same numbers of protons in the nucleus (and corresponding electrons). It's not so much "can have", as "do have". It's just a different number of neutrons that makes a different isotope.

Any of two or more forms of a chemical element, having the same number of protons in the nucleus, or the same atomic number, but having different numbers of neutrons in the nucleus, or different atomic weights.

Isotopes are identified based on their mass number, which is the sum of the number of protons and neutrons in the nucleus of an atom. This information can be obtained through techniques such as mass spectrometry or by analyzing the atomic mass of an element, which is a weighted average of the masses of its isotopes.

No. All Uranium isotopes are called Uranium because they have 92 protons. The different isotopes (233, 235, 238, etc) all have 92 protons but have different numbers of neutrons in the nucleus. The chemical characteristics of an atom are determined by the number of protons in the nucleus which controls the number of electrons it takes to balance the atom and thus the chemical valence of the atom.

When you get down to it, that is the reason why enrichment of Uranium is such a difficult task since there is only a three neutron difference in weight between fissionable U235 and non-fissionable U238 and no difference in chemical properties.

After three half-lives, 12.5% of the radioactive isotope is remaining. This is because each half-life reduces the amount of radioactive material by half.

Hot labeling involves incorporating a radioactive isotope into DNA during sequencing, offering high sensitivity but potential hazards. Cold labeling uses non-radioactive isotopes, like fluorescent dyes, for safer detection. Both methods aid in tracking DNA fragments during sequencing.

Not a lot at all. Most mouthwashes can be used as gargles as most have a disinfectant or antibacterial solution, But some gargles are medicated and meant just to be gargled and not to be used as a mouthwash. I would say that Listerine would be both a mouthwash and a gargle, but Hydrogen peroxide (H2O2) would be a gargle only.

It depends what you want to use it for. They are extremely dangerous and can kill you if exposed to the wrong kind, but they are also how much of the world's electricity is produced. Radioactive isotopes are also commonly used in medicine for a number of beneficial purposes. Radioactive isotopes are also what nuclear bombs use. Like most things in the world, they can be used for great good, and terrible harm... it just depends on what you do with it.
