What isotopes of uncharded elements have different numbers?
The atomic number of the isotopes of an element is identical; the mass number is different.
Why can you subtract the atomic number from the atomic mass and get the number of neutrons?
Not the atomic mass but the mass number (of course, these values are similar - not identical).The mass number is the sum between the number of protons and the number of neutrons. As a consequence:Number of neutrons for an isotope = Mass number - Number of protonsThe number of protons is equal to the atomic number.
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 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 is atomic mass of many elements not a whole number?
The main reason that the Atomic Mass of elements is not a whole number is due to the presence of different isotopes - these have the same number of protons in the nucleus but a different number of neutrons - so their masses are different even though chemically they are identical. The two isotopes of Chlorine are 35Cl- (75.77%) and 37Cl (24.23%) giving an overall "average" mass of 35.4527.
Atomic mass differing from atomic mass number?
Those are different facts. atomic number is total of protons and neutrons.
What is the difference between isobar and isotope?
isobars are elements with same mass numbers (Atomic Mass) and different atomic number (number of proton or electron)
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
How can two atoms of an element can be different?
Isotopes : a different number of neutrons. The chemistry is almost identical (mainly the reaction times are slightly different.
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
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 may neutrons does neon have?
Number of neutrons = Atomic mass - Atomic number Atomic number of neon: 10 Atomic mass: depending on the neon isotope, each isotope has a different mass
