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.)
What are the atoms called then they have the same atomic number but different mass numbers?
They are called as isotopes in which mass number differ by emmision of radiation
What is the atomic number for the oxygen atom?
The mass number is the sum of neutrons and protons in the atomic nucleus and is different for each isotope of any element. For example the isotope oxygen-16 has the mass number 16. The atomic weight of oxygen (not Atomic Mass) is [15,99903; 15,99977] after the IUPAC Tables - 2009. The atomic number of oxygen is 8.
What are atoms that have the same number of protons but different mass number?
Atoms with the same number of protons but different mass numbers are called isotopes. Isotopes have the same atomic number but different atomic weights due to variations in the number of neutrons in the nucleus.
How do you know the number of neutrons an atom has?
You can find the number of neutrons in an atom by subtracting the atomic number (number of protons) from the atomic mass number (rounded atomic weight). The atomic mass number represents the sum of protons and neutrons in the nucleus.
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.
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
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
How many neutrons dose hassium have?
Number of neutrons = Atomic mass of an isotope - Atomic number of the element The atomic number of hassium is 108; each isotope of an element has a different number of neutrons and a different atomic mass.
How are atomic mass and atomic number different?
Atomic number is the number of protons in the nuclei of the atoms of an element. Atomic number is unique to each element. Atomic Mass is the combined mass of the protons, neutrons, and electrons in an atom of an element.
What is an atomic mass number?
Atomic mass and atomic number are two different things. Atomic mass is the mass of an atom compared to that of hydrogen. The atomic number is the atom's position in the periodic table. It's also the number of protons it has.
Do isotopes of an element have the same atomic mass but different atomic number?
The different mass numbers are due to different numbers of neutrons.
