Isotopes
Isotopes are atoms that have different number of neutrons, so they have a different mass number than the other atoms in an element.

Explain why the GNP and GDP are different?
A country's Gross Domestic Product, or GDP, is the amount of goods and services, measured at market prices, produced within the country during a particular time period (usually a year). Gross National Product, or GNP, is the amount of goods and services produced by residents of a country, regardless of where that production takes place.

Remember, GDP concern is BORDER, whereas GNP concern is PRODUCER.

The atomic number of an element is the number of protons in its nucleus. Always. The mass number of an atom is the number of protons plus the number of neutrons in it. And that means an isotope of element 54 (xenon) that has 77 neutrons in its nucleus has a mass number of 54 + 77 or 131, and you'll have an atom of 131Xe. A link can be found below.
Are the three isotopes of carbon chemically alike?
Yes, the three isotopes of carbon (carbon-12, carbon-13, carbon-14) are chemically alike because they all have the same number of protons and electrons, which determine the element's chemical properties. The only difference is in their atomic mass due to the varying number of neutrons.
Is aluminum an isotope ion or neutral atom?
Aluminum has a number of isotopes 26Al and 27Al, with27Al being by the far most commonly occurring in nature 99.99999%.
In some chemical compounds aluminium can be ionic, forming the Al3+ ion
An atom of aluminium is neutral
What is the mass number of the most common isotope of carbon?
As the atomic number of nitrogen is 7, the most abundant isotope of this atmospheric gas must have 7 neutrons (14.007 - 7 = about 7), and this will make nitrogen-14 that isotope that is most abundant.
How are the three isotopes of hydrogen alike?
The three isotopes of hydrogen are called: hydrogen (1H or H, no neutrons), deuterium (2H or D, one neutron), and tritium (3H or T, two neutrons).
They each have their own special name to make it easier to refer to them. They are fairly commonly used in chemistry and physics (especially deuterium).
How do the isotopes hydrogen-1 and hydrogen-2 differ?
Hydrogen-1 has no neutrons while Hydrogen-2 has 1 neutron
A hydrogen-1 atom (normal hydrogen) has 1 proton and 1 electron whereas a hydrogen-2 atom (deutrium) has 1 proton, 1 NEUTRON and 1 electron.

What are the examples of isotopes?
Hydrogen has three isotopes one proton and no nutron one proton and one nutron one proton and two nutrons
What is the difference between an ion and an isotope?
an ion has a different number of electrons and an isotope has a different number of neutrons then listed on the Periodic Table or your sample
What are the most common isotopes of europium?
The most common isotopes of europium are europium-151 (Eu-151) and europium-153 (Eu-153). Eu-151 is stable and non-radioactive, while Eu-153 is a radioactive isotope with a half-life of about 4.7 years.
List the isotopes used in agriculture?
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.
Is the element with atomic number eight an isotope?
The element with atomic number eight is oxygen, and anyatom of oxygen is an isotope. Let's see how that works.
The word isotope speaks to the number of neutrons in a given atom of a given element. When we speak of oxygen, we might consider any of its isotopes, but all atoms of this element have eight protons in their nucleus. They're all oxygen, and all have atomic number eight. Oxygen has three stable isotopes, and they are O-16, O-17 and O-18. All atoms of these isotopes have eight protons in them, but they have eight, nine and ten neutrons in their nuclei, respectively.
An element has 22 protons 20 electrons and 26 neutrons What isotope is it?
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).
Why do isotopes of the same element have the same chemical behavior?
- 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.
What are the everyday uses of an isotope?
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.
What are the common isotopes of Rhodium?
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.
Different isotopes have different what?
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.
How are all of the isotopes of an element similar?
by having the same number of protons and electrons and so still have the same chemical properties and physical properties with the exception of being somewhat denser.
All of the isotopes of an element contain the same number of protons. They differ only in the number of neutrons.
The number of electrons is an ionization state issue, and does not affect isotopic identity.
Why must different isotopes of the same element have different physical properties?
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.)
Uranium 235 and uranium 238 are isotope they are chemically different why?
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.

What way do isotopes of an element differ?
I do not know about anything beyond that, but that much I'm certain on.
I don't know about the above answer but from what I know in Chemistry is that the protons is what makes the isotopes of each element differ and the neutrons. Hope this helps
I think the first answer is correct. The protons do not make any difference. That's from AP Bio knowlege.
What changes occur when a radioactive isotope disintegrates?
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.
