Isotopes

Isotopes commonly used in agriculture include carbon-14 for carbon dating of soil and organic matter, nitrogen-15 for studying nitrogen uptake in plants, phosphorus-32 for tracing phosphorus movement in soil and plants, and potassium-40 for studying potassium uptake in plants.

The element with 22 protons is titanium (Ti). The sum of protons and neutrons determines the isotope, so with 26 neutrons, the isotope is titanium-48 (22 protons + 26 neutrons = Ti-48).

1. Chemical properties of a element is governed by ELECTRONIC CONFIGURATION of that element. As isotopes of same element have identical electronic configurations, their chemical properties are same.

The everyday uses of an isotope include food irradiation, medical applications, archaeological dating, and in instruments like smoke detectors. Some medical uses are for bone imaging and radiation therapy for cancer.

The common isotopes of Rhodium are Rh-103, Rh-101, Rh-102, Rh-102m and Rh-99. They also happen to be stable. In addition to these isotopes, there are 30 other Rhodium isotopes.

The isotopes of an element must have a different amount of neutrons.

I'm pretty sure you know what these are, but just in case:

A neutron is a sub-atomic part of an atom, together with protons and electrons.

Isotopes are atoms of an element having different numbers of neutrons. The atomic mass of an atom is approximated by the number of neutrons plus the number of protons; it follows, then, that isotopes of an element differ in their atomic masses.

Mass itself is a physical property. Other properties related to mass also vary by isotope: density (mass/volume), boiling point, freezing point, and the degree of ion deflection in a mass spectrometer are perhaps the most obvious of these related properties. The rate of diffusion is also affected; as per Graham's law of effusion, the rate of diffusion of a gas is inversely proportional to the square root of its molecular mass. (This property played a crucial role in the development of the atomic bomb.)

I LIKE PIGS IN A BLANKET I think ,because when hit Uranium-238 by a neutron, it becomes uranium-239, an unstable isotope which returns into neptunium-239, which then itself decays, with a half-life of 2.355 days, into plutonium-239. ------------------------ Differences in nucleus stability and nuclear cross sections for fission with thermal neutrons. Some details at: http://nuclearweaponarchive.org/Library/Fission.html

When a radioactive isotope disintegrates, it releases radiation in the form of alpha or beta particles, gamma rays, or neutrons. This process changes the atom's nucleus, leading to the formation of a different element or isotope. The disintegration continues until a stable atom is reached.

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.
