Correct nuclear notation for isotope -15?

Be, B, C, N, O and F have an isotope with the mass 15. Example for nitrogen: 157N (15 is the atomic mass of the isotope, 7 is the atomic number of nitrogen). For other elements, of course, the atomic number is different.


What is the isotope notation for thorium?

Unfortunately WikiAnswers doesn't accept subscript/superscript.For the isotope thorium-232: 232Th90232 is a superscript (mass number) and 90 is a subscript (atomic number).


How can you dertermine the number of neutrons in a isotope?

Subtract the atomic number of the isotope from its atomic mass number to obtain the number of neutrons in an isotope.


How does the atomic number relate to the number of protons in an atom?

Atomic Mass (of an isotope) - number of protons (of an isotope) = number of neutrons (of an isotope)


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


What does the atomic mass equals the number of?

An isotope's mass number is the sum of the protons and neutrons in each atomic nucleus of the isotope.


What is nuclear notation?

notation for an isotope of an element where the subscript is the atomic number, the superscript it the mass number, and they are attached on the left of the symbol for the element.Example: 11H (kind of like that, but with no space between the 1s, it's just 1 directly over 1, then H)


How many neutrons is in californium?

153 neutrons in the most stable isotope Number of neutrons = Atomic mass of an isotope - atomic number. Atomic mass of the most stable isotope of Cf is 251. Atomic number of Cf is 98.


What is the atomic mass number of an isotope that has an atomic number 5 and includes 6 neutrons?

The atomic mass number of an isotope is the sum of the number of protons and neutrons in the nucleus. In this case, atomic number 5 represents the number of protons, and adding the 6 neutrons gives an atomic mass number of 11 for this particular isotope.


How do you find atomic mass and mass number of isotope?

The atomic mass of an isotope is the weighted average of the masses of the naturally occurring isotopes of an element. It is found by multiplying the mass of each isotope by its natural abundance and summing these values. The mass number of an isotope is the total number of protons and neutrons in its nucleus and can be found by rounding the atomic mass to the nearest whole number.


Was is the atomic mass number for oxygen?

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 mass number is not the atomic mass !!


How many protons and neutron and electron and nucleus electron cloud are the in curium?

Curium has 96 protons. Number of neutrons = Atomic mass of an isotope - atomic number of the isotope The atomic number of curium is 96; for the isotopic masses of curium read at the link below.
