They have the same number of protons and therefore the same chemical properties. But they have different numbers of neutrons and so the atomic masses are different and so are some physical properties.
Each atom of an isotope of beryllium (or of another element) is different from the atoms of an other isotope. But all the atoms of an isotope are identical.
It depends on the isotope.
That ratio is known as the isotopic composition of the element. It tells you the proportion of the specific isotope compared to all isotopes of that element in the mixture. This ratio is important in various applications, such as radiometric dating and isotopic analysis in chemistry and physics.
isotope
Atoms of the same element that differ in number of neutrons
Each atom of an isotope of beryllium (or of another element) is different from the atoms of an other isotope. But all the atoms of an isotope are identical.
They would have to be atoms of the same element, and the same isotope of that element.
Percent abundance is calculated by determining the proportion of a specific isotope of an element relative to the total amount of all isotopes of that element. To find it, divide the number of atoms of the isotope by the total number of atoms of all isotopes, then multiply by 100 to convert it to a percentage. For example, if an element has two isotopes, with 75 atoms of isotope A and 25 atoms of isotope B, the percent abundance of isotope A would be (75 / (75 + 25)) × 100 = 75%.
The antonym for isotope is non-isotope. An isotope refers to atoms of the same element with different numbers of neutrons, whereas non-isotope would refer to atoms of the same element having the same number of neutrons.
An isotope has extra/fewer neutrons than the original atom. So if you know the isotope you can deduce the original atoms' formula.For Ca that would be:20 protons40 mass number
The time it takes for half of an isotope's atoms to decay is called the half-life. It is a characteristic property of each isotope and can vary greatly depending on the specific isotope.
Isotope
an isotope?
A compound is a mixture of two or morel types of atoms. An isotope is a single atom of one element with a different number of neutrons. They are not the same thing.
the two atoms belong to two different elements
21H is a radioactive isotope of hydrogen known as tritium. It has two neutrons in addition to the single proton found in regular hydrogen atoms.
One of two or more atoms having the same atomic number but different mass numbers.
