in case of some elements which has isotopes the atomic masses are different so the average is taken out which may come in decimals.
What else can I help you with?
Is the atomic mass of an element is always a whole number of atomic mass untis?
No.
Why is the atomic mass of an element not a whole number while the atomic number is?
The atomic number refers to the number of protons in the atom. Since the proton cannot be an in-between number, the atomic number will have to be a whole number. On the other hand, the atomic mass does not have to be a whole number because it is the mass of an atom and is roughly equivalent to the number of protons plus the average number of neutrons in that particular element.
What is an element's atomic mass not listed as a whole number on the periodic table?
Few elements have isotopes. their atomic mass is not a whole number.
What element has an atomic mass of 32.06?
Sulfur- Element Number 16 on the Periodic Table of Elements
What would cause the average atomic mass to be close to a whole number?
The average atomic mass of an element is close to a whole number when the element has nearly equal amounts of its isotopes, with atomic masses that are close to whole numbers themselves. This occurs in elements with only one stable isotope or with stable isotopes that have similar abundances.
How do you calculate neutrons for elements in the periodic table?
them mass number of an element is the total amount of nuetrons and protons in the element , and the atomic number is the amount of protons ( and electrons) in the element simply subtract the atomic number from the mass number and you'll have the number of neutrons in the element hope this helped x
Can explain in terms of isotopes why the relative atomic mass of atomic number 17 is not a whole number?
Mass number is the average of all the naturally occurring isotopes of that element. When calculated, this average is not a whole number.
The difference between the atomic number of an element and its atomic mass?
The atomic number of an element represents the number of protons in its nucleus, which determines its position on the periodic table and its chemical properties. The atomic mass (or atomic weight) of an element reflects the average mass of its isotopes, considering both protons and neutrons. In general, the atomic number is a whole number without units, while atomic mass is usually expressed in atomic mass units (amu).
Why atomic mass is always a whole number but atomic weight may be a decimal number?
Atomic mass is the total mass of protons and neutrons in an atom, which are whole numbers. Atomic weight, on the other hand, takes into account the abundance of different isotopes of an element, which can result in a weighted average that may be a decimal number.
What is the mass of an element?
The mass of an element is determined by the total number of protons and neutrons in its nucleus. This mass is typically measured in atomic mass units (amu) and is an average of all the naturally occurring isotopes of that element.
How do you find the number of neutrons AM element has?
To find the number of neutrons in an element, you need to know its atomic mass (rounded to the nearest whole number) and its atomic number. The atomic number represents the number of protons in the nucleus, and since the number of neutrons can vary (resulting in different isotopes), you can calculate the number of neutrons by subtracting the atomic number from the atomic mass: Neutrons = Atomic Mass - Atomic Number. For example, if an element has an atomic mass of 12 and an atomic number of 6, it has 12 - 6 = 6 neutrons.
How do you figure the number of neutron's in an atom?
Take the Atomic Mass and round it to the nearest whole number. Then subtract this number and the atomic number of that element.
