Does an isotope of an element have a different atomic mass?
Yes, isotopes of an element have the same number of protons but different numbers of neutrons, leading to variations in atomic mass. This is why the atomic mass on the periodic table is often listed as a range for an element.
What number is the whole number found in the periodic table?
There are two numbers that are included in every element's block on every periodic table. The whole number, which can range from 1 - 118 is the atomic number of that element. The atomic number is the number of protons in the nuclei of the atoms of that element. The second number is the atomic weight and is never a whole number, except for the artificially prepared elements, and then it is a whole number written inside parentheses.There may be other numbers listed as well, depending on the periodic table. All periodic tables have a key as to what everything inside each block represents.
How can a set of numbers have a range of zero?
A set with only one element. Its maximum = minimum = that element. So the range = max - min = 0.
What are atoms of the same element that have different neutron numbers called?
Every atom of the same element is also categorized by its number of neutrons. An atom with a certain number of neutrons is an "isotope." Two atoms of the same element (same quantity of protons) can be different isotopes (different quantity of neutrons). Some isotopes are unstable, so most stable isotopes of an element are withing a range of a few numbers. For example, stable isotopes of carbon are Carbon-12 and Carbon-13.
What is the relationship between the atomic number and the atomic mass number?
Atomic number: number of protons in a nucleus unique to an element Atomic Mass number: number of protons + number of neutrons in a nucleus. May be a small range of values for a given element. Very roughly the atomic mass number is double the atomic number. For large elements it is more than double.
What is function and relation?
All functions are relations with the condition that each element of the domain is paired with only one element of the range. A relation is any pairing of numbers from the domain to the range.
What is relations function?
All functions are relations with the condition that each element of the domain is paired with only one element of the range. A relation is any pairing of numbers from the domain to the range.
Can each atom of a specific element have the same number of protons or atomic mass or number of neutrons or atomic weight or none above?
an element is distinct from others by the number of protons, change the number of protons you have a different element1. The number of elections can be altered creating ions2 and the number of neutrons can be different which are isotopes. so the atomic weight can change between ions and isotopes of the same element. 1. breaking down of the nucleus called radiation. 2. cations + charge: number of protons greater then elections anions - charge: number of elections greater then protons
Do you use the 0 when finding the range of a set of numbers?
If there is an element of the domain that is mapped on to 0 then yes, else no.
Why are there variations in atomic mass?
The isotopic composition of natural uranium is not absolutely identical in all ore samples; this is valid also and for other elements. The long geological evolution can influence the isotopic composition.
How do you determine protons electrons and nuetrons in an element?
A periodic table is your best bet.periodic tables can range in complexity but most will tell you the atomic number (located left upper corner) and the average atomic mass (right upper corner). with these two numbers you can work out protons and neutrons by realizing that the atomic numbers is = to # of proton and that because the proton and neutrons are ~1 amu in mass with electron have negliable massAverage atomic mass - atomic number = # of neutronsyou will realize that this # is often not a whole number. that is because the same element (elements with same atomic number) may have different numbers of neutrons and the average atomic these are called isotopes. most elements will have a main isotope and some minor isotopes that makeup a same percentage of the total.this is why you often see average mass of xx.99 like Cr which is 51.996 meaning that most of the isotopes will have a atomic mass of 52 (24 protons and 28 neutrons) and a relatively small percentage will have a mass of 51 (again 24 protons because it is still Cr but now 27 neutrons)As for the number of electrons, this depends on what kind of chemistry the element is involved with. Just keep in mind that a neutrally charged molecule has the same number of + charges (protons) as - charges (electrons)
How many protons are in an atom of bismuth?
== The element bismuth has 83 protons. That's its atomic number. Remember that it's the number of protons in an element that determines the atomic number of that element. All atoms of bismuth have 83 protons. As to neutrons, the number of neutrons in bismuth atoms can vary. These other "flavors" of bismuth are its isotopes, and the numbers of neutrons in bismuth range from 101 to 135. It is bismuth-209 with 126 neutrons that represents all the natural bismuth we find. The rest of the isotopes are intentionally synthesized or created "incidentally" in nuclear reactions - like those in nuclear reactors, to cite one example.
