Isotopes

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

How isotopes can have different masses and still be the same element?

User Avatar

Asked by Wiki User

For the same element the number of protons and electrons remains unaltered.

Howerm for that same element the number of neutrons can vary., leading to different atomic masses.

Taking hydrogen as an example. It has three isotopes.

#1 ; protium ; 1 proton , 0 neutrons (Atomic Mass ; 1 + 0 = 1 )

#2 ; deuterium ; 1 proton , 1 neutron ( Atomic mass ; 1 + 1 = 2)

#3 ; tritium ; 1 proton, 2 neutrons ( Atomic Mass ; 1 + 2 = 3)

Notice for each isotope of hydrogen there is only ONE proton. However, for each different isotope of hydrogen there is a different number of neutrons.

The Atomic Mass is the sum of the protons and neutrons).

#4 ; Helium(He) ; 2 protons, 2 neutrons ( atomic mass 2 + 2 = 4 ).

For comparison helium has 2(TWO) protons and 2 neutrons, but it is an entirely different element, because it has a different number of protons.

Are there 2 neutrons in the helium 4 isotope?

Asked by Wiki User

No, there are actually 2 protons and 2 neutrons in the helium-4 isotope. The number of protons determines the element, while the sum of protons and neutrons gives the atomic mass of an isotope.

What are short-lived isotopes?

User Avatar

Asked by Wiki User

Short-lived isotopes are radioactive isotopes that have a relatively short half-life, which is the time it takes for half of the radioactive atoms to decay. These isotopes decay rapidly and do not persist in the environment for a long time. They are often used in medical imaging, research, and various industrial applications.

What is the meaninq of two isotopes stable and unstable isotopes?

User Avatar

Asked by Wiki User

Isotopes are atoms of the same element with different numbers of neutrons. Stable isotopes have a balanced number of protons and neutrons, meaning their nuclei do not decay over time. Unstable isotopes, also known as radioactive isotopes, have an imbalance of protons and neutrons, causing their nuclei to decay and emit radiation over time.

An isotope is identified by its atomic mass number which is the total number of?

Asked by Wiki User

protons and neutrons in the nucleus of an atom. Isotopes of an element have the same number of protons but different numbers of neutrons. The number of neutrons in an atom affects its stability and often determines its nuclear properties.

Which is an example of a highly unstable isotope that is often used in fission reactions?

User Avatar

Asked by Wiki User

Uranium-235 (U-235) is an example of a highly unstable isotope that is used in fission reactions. It undergoes spontaneous fission, releasing a large amount of energy and additional neutrons, which can then go on to induce fission in other uranium atoms, leading to a chain reaction.

Do isotopes have different electrical charges?

User Avatar

Asked by Wiki User

No, isotopes have the same electrical charge because they have the same number of protons in their atomic nuclei, which determines the electrical charge. Isotopes only differ in the number of neutrons, which do not have an electrical charge.

Where are isotopes located at?

User Avatar

Asked by Wiki User

Isotopes are located within the nucleus of an atom. They are variants of a particular chemical element, having the same number of protons but different numbers of neutrons. Isotopes can exist naturally or be artificially produced.

What is a isotope for hydrogen?

User Avatar

Asked by Wiki User

Deuterium is an isotope of hydrogen. It has one proton and one neutron in its nucleus, compared to regular hydrogen which has only one proton. Deuterium is slightly heavier than regular hydrogen and is often used in laboratory experiments and as a tracer in scientific studies.

What atomic particle that determines a specific isotope?

User Avatar

Asked by Wiki User

The atomic particle that determines a specific isotope is the number of neutrons in the nucleus of an atom. Isotopes are different forms of an element that have the same number of protons but a different number of neutrons. The number of neutrons affects the mass of the atom and gives rise to different isotopes with varying atomic weights.

Which isotope of hydrogen is used commonly as a trace in organic chemistry?

User Avatar

Asked by Wiki User

Deuterium (2H) is commonly used as a trace isotope in organic chemistry. It is a stable isotope of hydrogen that differs from the most common isotope, protium (1H), by having an additional neutron in its nucleus. Deuterium is useful in studying chemical reactions and metabolic pathways in organic molecules.

What is the most common instrument used to measure isotope?

User Avatar

Asked by Wiki User

The most common instrument used to measure isotopes is a mass spectrometer. Mass spectrometry allows scientists to accurately determine the mass and abundance of isotopes in a sample. It works by ionizing the atoms in the sample and separating them based on their mass-to-charge ratio.

What is meant by half life of radioactive isotopes?

Asked by Wiki User

This is the time in which half the the atoms was disintegrated.

What subatomic particle changes in an isotope?

User Avatar

Asked by Wiki User

I'm assuming that by "change" you mean alter the quantity thereof. If you want to actually change a proton into a nuetron and eject a positron, that requires a nuclear reaction.

The protons and neutrons are in the nucleus and serve to define the atom, while the electrons orbit the nucleus and ultimately determine the atom's charge. Electrons can be removed or added with a certain amount of energy. This energy is relatively small compared to the massive amounts required to alter the subatomic particles within the nucleus.

How are the Isotopes of strontium alike?

User Avatar

Asked by Wiki User

They have the same number of protons (and of electrons) and so their chemical properties are the same.

How can you determine the number of neutrons in an isotope?

User Avatar

Asked by Wiki User

One doesn't generally "calculate" the number of neutrons. The number of neutrons in an atom is always equal to the number of protons, and the number of protons can be found on the Periodic Table of Elements, which can easily be found on the internet or in a science textbook.

Would carbon dating work if carbon-14 atoms did not decay at a constant rate and why?

Statistically carbon-14 atoms decay at a constant rate.

Is 1-hexyne an isotope?

User Avatar

Asked by Wiki User

No, 1-hexyne is not an isotope.

Isotopes are same elements that have the same number of protons (and therefore the same chemical properties) but different numbers of neutrons. They have slightly different atomic masses due to the varying number of neutrons in their nuclei.

1-hexyne, on the other hand, is a specific chemical compound. It is an alkyne with the molecular formula C6H10 and a carbon-carbon triple bond at the first position in a hexane chain. Isotopes are not specific chemical compounds, but they are variations of elements.
