What else can I help you with?
Can an atom of two different elements have the same mass number?
Yes. The mass number is basic to the different elements, even more useful than the atomic number. (Unless it is an isotope. Isotopes have a different amount of neutrons than the basic element atom which makes a difference in mass number too. So, a difference in mass numbers doesn't always mean it is a different element.)
Why the mass number of the same atom of an element is not constant?
Since you have isotopes of elements. Isotopes are elements with different number of neutrons hence why the different atomic masses for the same elements.
What has a different mass number than the normal atom?
We can find atomic mass and mass number in chemical elements. Atomic mass is about weight of the atom. Mass number is about total of neutrons and protons.
What is the atom with same atomic number but different mass number?
We can find atomic mass and mass number in chemical elements. Atomic mass is about weight of the atom. Mass number is about total of neutrons and protons.
Why atomic mass is different from the mass numbers?
atomic mass is the number of protons in an atom mass number is the number of protons plus neutrons in an atom
Do Isotopes of uranium have different atomic numbers?
No. By definition isotopes of an element have the same number of protons (that is what makes them uranium, for example) but different numbers of neutrons (neutral particules in the nucleus which provide mass).
How do you you find the mass number of an atom?
To find the mass number of an atom, you add together the number of protons and neutrons in the nucleus of the atom. The atomic mass listed in the periodic table is the weighted average of the mass numbers of all isotopes of that element.
Why is the atomic mass number not a whole number?
We can find Atomic Mass and mass number in chemical elements. Atomic mass is about weight of the atom. Mass number is about total of neutrons and protons.
Why do you subtract the atomic number from the mass number?
We can find atomic mass and mass number in chemical elements. Atomic mass is about weight of the atom. Mass number is about total of neutrons and protons.
What is the atomic mass of an element the number?
We can find Atomic Mass and mass number in chemical elements. Atomic mass is about weight of the atom. Mass number is about total of neutrons and protons.
What is the mass number and what equation can it be written in?
We can find atomic mass and mass number in chemical elements. Atomic mass is about weight of the atom. Mass number is about total of neutrons and protons.
Why can an atom have more then one mass number but only one atomic number?
First of all, an atom can not literally have either more than one mass number or more than one atomic number. Different atoms of the same element can have different mass numbers but the same atomic number because the atomic number is the defining characteristic of an element, but many elements have isotopes that have different numbers of neutrons in their nuclei and therefore different mass numbers: Mass numbers are the sum of the numbers of protons and neutrons in the nucleus.
