What else can I help you with?
Atomic mass differnet from the atomic mass number why is that?
The atomic mass is an average, allowing for the relative abundances of different isotopes.
What is kryptons average atomic mass number?
The Atomic Mass of krypton is 83.80(1) if you round 84
Why is atomic mass not a constant number?
The atomic mass is the average of all of the different isotopes of the element present in the sample. Samles taken from aound the worlld for some elements have slightly different isotope ratios and therefore have different atomic masses.
Is there an element that has the same atomic number and atomic mass?
No, there is no naturally occurring element with the same atomic number and atomic mass. The atomic mass of an element is the weighted average of the masses of its isotopes, which have different numbers of neutrons. The atomic number of an element is the number of protons in its nucleus, which determines its identity. Therefore, the atomic number and atomic mass are different for each element.
Why is the atomic mass of strontium not a whole number?
The atomic mass of strontium is not a whole number because it is an average value that takes into account the abundance of different isotopes of strontium in nature. These isotopes have different masses and occur in different proportions, resulting in a weighted average atomic mass that is not a whole number.
Atomic mass differnet from the atomic mass number why is that?
The atomic mass is an average, allowing for the relative abundances of different isotopes.
How many protons and neutrons are in the nucleus of the atom?
No it is not the atomic number. We call it mass number.
What does a mass number determine?
mass number = number of protons + number of neutrons DIFFERENT FROM ATOMIC MASS atomic mass = weighted average of all the isotopes of that element
Is atomic mass and mass of an atom different?
No, they are not different. The atomic mass number is the average of the total number of the protons and neutrons in the atom of the existing isotopes of an element. That's why the atomic mass number is sometimes not a whole number but a decimal number as in oxygen being 15.999. FYI isotopes are different atoms of the same element that contain the same number of protons but have a different number of neutrons.
What is kryptons average atomic mass number?
The Atomic Mass of krypton is 83.80(1) if you round 84
Why is atomic mass not a constant number?

Weighted average atomic mass?
What is weighted average atomic number
What is the average atomic mass compared to the atomic mass?
Atomic Mass is the number of protons and neutrons in an atom.
Is there an element that has the same atomic number and atomic mass?
No, there is no naturally occurring element with the same atomic number and atomic mass. The atomic mass of an element is the weighted average of the masses of its isotopes, which have different numbers of neutrons. The atomic number of an element is the number of protons in its nucleus, which determines its identity. Therefore, the atomic number and atomic mass are different for each element.
Why is the atomic mass of strontium not a whole number?
The atomic mass of strontium is not a whole number because it is an average value that takes into account the abundance of different isotopes of strontium in nature. These isotopes have different masses and occur in different proportions, resulting in a weighted average atomic mass that is not a whole number.
What is the difference between the average atomic mass given on the periodic table and the mass of an atom?
The average atomic mass on the periodic table represents a weighted average of all isotopes of an element based on their natural abundance, not the mass of a single atom. In contrast, the mass of a specific atom (or isotope) is an exact value for that isotope.
Does atomic number equal atomic mass?
No, the atomic number and atomic mass are different. Atomic number represents the number of protons in an atom's nucleus, while atomic mass is the average mass of an atom of an element, taking into account the number of protons and neutrons.
