What is the mass number of 15.9994?
The mass number of an element is the sum of the number of protons and neutrons in the nucleus of an atom. For an atom with a mass number of 15.9994, it indicates the average atomic mass of an oxygen atom.
The mass number of an element is the number of?
Mass number is the atomic mass of a particular isotope (apex chem 5.3)
In order to calculate the number of neutrons you must subtract the from the?
In order to calculate the number of neutrons, you subtract the atomic number (number of protons) from the atomic mass (rounded to the nearest whole number). Neutrons are important for stabilizing the atomic nucleus alongside protons.
What is the mass number and atomic number of nitrogen?
Nitrogen has a mass number of 14 and an atomic number of 7.
What is mass number of krypton?
The mass number of krypton is 84.
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.
What is the form of nuclear energy?
Nuclear energy as used in power plants results from fission of uranium235 and plutonium239
What mass number is americium?
The mass number of Am-241 is 241; each isotope has another mass number.
How do you find the number of neutrons from the mass number?
To find the number of neutrons from the mass number, subtract the atomic number from the mass number. The atomic number represents the number of protons in an atom, and by subtracting it from the mass number, you can determine the number of neutrons present.
Can mass be a number?
yes mass can be a 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
What is the mass number for sodium?
The mass number for sodium is 23.
Mass number - atomic number equals?
Mass number minus the atomic number equals the number of neutrons. Mass number is the number of particles in an atom that have significant mass. Electrons are assigned a value of 0 since the mass is so much smaller than protons and neutrons. Protons and neutrons are similar in mass and are assigned mass number of 1. The formula for calculating atomic mass atomic mass = # protons + # neutrons.
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.
Why is the atomic mass number not a whole 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.
