In order to calculate the number of neutrons you must subtract the from the?
Number of neutrons = Mass number - atomic number
The mass number of an element is the number of?
Mass number is the atomic mass of a particular isotope (apex chem 5.3)
Can you use the mass number of an element to determine the number of electrons in an atom?
Mass number = number of protons + number of neutrons Number of electrons = number of protons = mass number of an isotope - number of neutrons
What is the mass number of a atom?
the mass number is number of protons in an atom, plus the number of neutrons.
What is the mass number of deterium?
The mass number of deuterium is 2
Atomic energy is the energy of heat mass or fluorescence?
Atomic energy is produced when atoms of uranium235 or other fissile material split, or undergo fission. It is nothing to do with fluorescence, and I don't understand 'heat mass'
What is one bad use of uranium235?
can cause lung cancer
What is true about the fission of uranium235?
The reaction produces more neutrons than were needed to start it.
A uranium235 sample starts with 200 atoms and 700 million years later there are 100 atoms What is the halflife of uranium235?
700 milliion years. The definition of half-life is the period of time during which one-half of the atoms of an element undergo decay into other elements.
What is the form of nuclear energy?
Nuclear energy as used in power plants results from fission of uranium235 and plutonium239
Can mass be a number?
yes mass can be a number
In order to calculate the number of neutrons you must subtract the from the?
Number of neutrons = Mass number - atomic number
How do you find the mass number of an element?
The formula for mass number is number of neutrons = mass number - atomic number. Mass number can also be referred to as nucleon number.
How do you find the number of neutrons from the mass number?
Atomic mass is the number of protons in an atom mass number is the number of protons plus neutrons in an atom the number of neutrons would equal the mass number minus the atomic number.
What is the mass number for the element uranium?
The atomic weight of uranium is 238,02891(3) atomic mass units. The mass number is the total number of nucleons (protons an neutrons) in the nucleus; the mass number is different for each isotope: 234U: mass number 234 235U: mass number 235 238U: mass number 238
How can you get the mass number and atomic number of element?
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 do you subtract the atomic number from the 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.
