What else can I help you with?
What determines mass number?
The mass number is the sum of neutrons and protons in the nucleus of an isotope.
Does atomic no of elements determine their chemical properties?
It determines which element, which all have their own properties so yes. The mass number just determines the isotope which only affects their stability
What determines the different isotopes from an atom?
The name of the element and the mass number (number of protons + neutrons) it is written e.g Uranium-235 or symbolically 235U
Which isotopes have the same mass?
The number of protons and neutrons is what determines the mass of an isotope. Even though isotopes of a particular element have the same number of protons, but a different number of neutrons, which causes their mass to be different.
What does the number of neutrons determine?
The number of neutrons in an atom determines the isotope of the element. Isotopes of an element have the same number of protons but differing numbers of neutrons. This affects the stability and nuclear properties of the atom.
Are there 2 neutrons in the helium 4 isotope?
Yes. He-4 isotope has 2 protons, 2 electrons and 2 neutrons
The mass of the mixture of the isotopes for an element?
The mass of a mixture of isotopes for an element is a weighted average of the masses of each isotope, calculated based on the isotope abundances. The formula for calculating the average atomic mass is: (mass of isotope 1 x abundance of isotope 1) + (mass of isotope 2 x abundance of isotope 2) + ...
What is the nucleus of an isotope with a certain atomic mass and number?
The nucleus of an isotope with a specific atomic mass and number contains protons and neutrons. The number of protons determines the element, while the sum of protons and neutrons gives the atomic mass. The neutrons in the nucleus help stabilize it by balancing the repulsion between positively charged protons.
What is the mass of the isotope 195Au?
195Au is an isotope of gold with a half life of about 186 days. It decays into 195Pt, an isotope of platinum. Its mass is 194.97 atomic mass units.
What part of an atom determines the isotope of an atom?
Neutron
An isotope of chlorine has 25 protons and 17 neutrons what is the mass number of that isotope of chlorine?
The mass number of an isotope is the sum of its protons and neutrons. In this case, the isotope of chlorine has 25 protons and 17 neutrons. Therefore, the mass number is 25 + 17 = 42. Thus, the mass number of this isotope of chlorine is 42.
What is the average atomic mass of an element is the average atomic masses of what kind of isotopes?
average atomic massof an element=(Atomic mass of first isotope X % of that isotope) + (Atomic mass of second isotope X % of the second isotope)
