What is the mass of nuetrons in 7mg of carbon14?
Carbon-14 has 6 protons and 8 neutrons. The mass of one neutron is approximately 1.0086649 atomic mass units (u). Therefore, the total mass of neutrons in 7 mg of Carbon-14 can be calculated by multiplying the number of neutrons (8) by the mass of one neutron to get approximately 8.0693192 mg.
Which has greatest number of neutrons carbon13 and carbon14 or nitrogen14?
C-13 has an atomic number of 6 and an atomic mass of 13, therefore it has 13-6 neutrons = 7. C-14 therefore has 8 neutrons. N-14 has an atomic mass of 14 and an atomic number of 7, so its number of neutrons is 7. 8>7, so Carbon 14 has the largest number of neutrons.
What Limitations are there of using carbon14 to date rocks?
The main limitations of using Carbon14 dating to find the age of something that is carbon base are firstly the possibility that carbon may be absorbed by some things making it more difficult to get an absolutely accurate age and secondly, with Carbon14 only having a half life of 5,568 years the maximum theoretical limit for detection is 100,000 years.
What do scientists use to determine a fossil's relative age?
Carbon14 dating (isotopic dating)
How many protons neutrons and electrons are in carbon14?
7 protons, 7 neutrons and 7 electrons
How do you find the atomic weight on the periodic table?
On many Periodic Tables, the small number directly below the chemical symbol is the atomic mass. On mine, there is a small 12.011 under the large C for carbon. While most carbon is 12, there are naturally occurring carbon13 and carbon14, so this is an average mass of all naturally occurring isotopes, with the majority of isotopes being carbon12
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?
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.
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 of 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.
