What is the term for atoms of the same element that differ in their mass numbers?
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 does the mass number?
By knowing mass number of the elements we can easily find out the number of neutrons presen in the nuclei.Physical properties of elements somewhat depends on mass number.
Why are some isotopes weighted more heavily than others?
The type of element is decided by the number of protons in it's nucleus. Number of neutrons are either equal or more than number of protons. Mass of proton and neutron is almost equal and that of electron is almost negligible as compared to both of others. As number of neutrons differ, mass of the elements also differ. Though they have 'same' chemical properties. Such atoms with different mass are called Isotopes. If the number of neutron is more, then such Isotopes are having more mass (or weight.)
How do isotopes differ and why is the atomic number of elements not a whole number?
Isotopes differ from each other by having different numbers of neutrons but the same number of protons since they are only the same element if they have the same number of protons. Atomic numbers aren't whole because their mass is based of the mass of hydrogen and amu's (atomic mass units) and due to how elements are formed, minute amounts of mass are lost in order to form the nuclear bonds resulting in not whole numbers.
Isotopes of the same elements differ in number of?
Neutrons
Isotopes of the same elements differ in their number of?
neutrons
Do radioactive elements differ in atomic number?
yes
Do neutrons differ in elements?
sure, neutrons differ in elements From the periodic table, they are fixed. However, there are also isotopes, where the element remains the same and contains the same number of protons but with different number of neutrons. For example, sulfur is present as 32S, 33S, 34S and 36S in nature. This means that the number of neutron + the number of proton in a sulfur atom can be 32, 33, 34 or 36. However, the constant in the 4 isotopes is that all of them contain only 16 protons.
How do nuclides 16 and 15 differ?
Nuclides 16 and 15 differ primarily in their atomic mass and the number of neutrons they contain. For instance, the nuclide with mass number 16 (such as oxygen-16) has 8 protons and 8 neutrons, while the nuclide with mass number 15 (such as nitrogen-15) has 7 protons and 8 neutrons. This difference in the number of protons also means they belong to different elements, affecting their chemical properties and behavior.
When atoms of the some elements differ in the number of neutrons?
isotopes
Does isotopes of elements differ in the number of neutrons in the nucleus?
yes
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.)
