Can the atomic mass of an element change?
For elements with multiple natural isotopes the precise atomic mass could vary from place to place. Depending on the ratio of those isotopes. Living systems are a natural way isotopic concentration change in some elements. Lighter isotopes react faster and living systems will tend to concentrate them. Extraterrestrial sources of elements could have significantly different isotopic composition than Earth's. Nuclear decay could change some isotopes to different elements. Thus changing the isotopic ratios.
How do you write 56000 in word notation?
we can write 56000 in word notation by fifty six thousand

You write 0.00007463 in scientific notation as: 7.463 × 10-5
HOW TO Write 0.0000037 in scientific notation?
HOW TO Write 0.0000037 in scientific notation.3.7*10-6
How to write 87200 in scientific notation?
the answer to how to write 87200 in scientific notation is 8.72*10^4
What is the isotopic notation for helium-4?
h27
What is the isotopic notation for chlorine-35?
3517Cl
What is the isotopic notation of Ca-35?
3520Ca
What are monoisotopic elements?
Mono isotopic elements are stable isotope of an element.From 80 isotopic elements there are 26 radioactive elements discovered up till now.These mono isotopic may or may not be radioactive if they are radioactive they have halve lives.
What is the isotopic notation of americium 241?
241 Am 95
What are elements with isotopic atoms?
Elements with isotopic atoms? An isotope is the same form of an element, but with a different number of neutrons. An element with isotopes/"isotopic atoms" is simply an element with isotopes.
What is the isotopic notation represents an atom of carbon-14?
6C 8
What is the isotopic notation of calcium-41?
Examples: 4120Ca, Ca-41, calcium-41; only the first is a scientific notation.
Are elements a pure mixture?
Chemical elements are not mixtures (I do not think to the isotopic composition).
What is noble-gas notation and why is it used to write electron configuration?
The noble gas notation is a notation formed as a result of the electron configuration notation being used in conjunction with noble gases. The noble gas preceding the element in question is written then the electron configuration is continued from that point forward. The notation is shorter to write and makes it easier to identify elements. The noble gas notation starts for elements after helium. For example, the electronic configuration of carbon is 1s2 2s2 2p2, whereas its noble gas notation is [He] 2s2 2p2.
How does noble-gas notation shorten the process of writing an elements electrons configuration?
In noble gas notation, you don't have to write the electron configuration up to that noble gas. You simply put the noble gas in brackets [noble gas] and then continue to write the electron configuration from that point. It just makes it shorter and easier to write electron configurations for elements with a lot of electrons.
Which of the following elements' isotopic ratios are used to make absolute determinations of the time of formation of materials?
oxygen
