A term used to describe any element or compound?
A term used to describe any element or compound is called a substance or substances.
What is the result when you total the individual percent abundance of isotopes of a given element?
How do you calculate percent abundance of an isotope?You find the isotope number and then you calculate that into a fraction and then turn the fraction into a percentage and divide it by the atomic number then times it by the mass and turn that answer into a percent and voila, there you have it.
What is the general term for any carbohydrate monomer?
what is one word that means carbohydrate monomer
What has 24 protons and 13 neutrons?
An atom with 24 protons and 13 neutrons would be chromium-37. This isotope of chromium has 24 protons in its nucleus, determining its element, and 13 neutrons, which along with the protons form its atomic mass.
Half life of the element Sodium?
There are several isotopes of Sodium, each with different half lives. The longest lived, Sodium-22, has a half-life of 2.6027 years.If you are interested in a different isotope, ask the question again and be specific about the isotope in the question.
A general term for any isotope of any element?
Nuclide
What is make an atom isotope?
It is the neutron that makes changes in atomic nuclei to change them from one isotope to another. For any given element, that element will have a fixed number of protons. It is, after all, the number of protons that determine the elemental identity. But the number of neutrons in a given element can vary, and we use the term isotope to talk about which particular atom we're investigating. That is, we apply the term isotope to speak to an atom of a given element with a certain number of neutrons in its nucleus.
Why need to know the percentage of each isotope of an element to determine the atomic mass?
Because each isotope of an element has a mass different from any other isotope of the same element, and the atomic mass of an element is an average, weighted by the proportion of each isotope, in the naturally occurring element.
The mass of the mixture of the isotopes for an element?
The mass of a mixture of isotopes for an element is a weighted average of the masses of each isotope, calculated based on the isotope abundances. The formula for calculating the average atomic mass is: (mass of isotope 1 x abundance of isotope 1) + (mass of isotope 2 x abundance of isotope 2) + ...
The number of protons and electrons found in an element?
In an atom of any isotope of any element, there is a number of protons which is similar to the number of electrons.
What is the opposites of an isotope?
The opposite of an isotope would be a pure element that does not contain any variations in the number of neutrons in its nucleus. This means that all atoms of that element have the same number of protons and neutrons.
The core element of any medical term is its what word?
The root is the core element of any medical term.
How many isotopes can there be in an element?
There is no specific number; each element has another number of natural and artificial isotopes.
How do you estimate the number of neutrons in the atoms of an element?
The number of neutrons in the nucleus of an atom of any isotope of an element is equal to the "atomic mass number", which is usually stated in a number immediately after a hyphen at the end of the element name in the name of the isotope, minus the atomic number. Because most elements have more than one stable isotope, the average number of neutrons in the mixture of isotopes of an element that occurs naturally is usually not an integer.
A term used to describe any element or compound?
A term used to describe any element or compound is called a substance or substances.
How is an isotope and mass number related?
It isn't, as such. Isotopes of the same element have different numbers of neutrons, and neutrons have a mas of one atomic mass unit (amu). So isotopes have different atomic masses, but being told the number of neutrons any isotope has, will not enable you to say what element or atomic mass it had, unless you remembered the details for every single isotope. Even then different elements can have the same number of neutrons. Isotopes do get named after their atomic mass however - uranaium 235 has an atomic mass of 235, for instance.
Technetium in brackets?
Any time you see the atomic mass of an element in brackets on the periodic chart, that number represents the mass number of the longest-lived or best-known isotope of that element. In other words there is no stable isotope, i.e. all forms of it are radioactive.
