6. An atomic number is always a whole number, so it does not need rounding.
atomic mass of carbon=12 atomic number of carbon=6
503.8, when rounded to the nearest whole number, is 504.
50.67 rounded to the nearest whole number is 51.
It is then 72 when rounded to the nearest whole number
It is 5 rounded to the nearest whole number
Typically to find the number of neutrons, you first round the atomic mass to the nearest whole number. After that to you subtract the number of protons (which is the same as the atomic number) from the newly rounded atomic mass and the resulting number is the number of neutrons. lets use Carbon for example: Atomic mass: 12.01 Atomic mass rounded: 12.00 Number of Protons (same as atomic number): 6 (Rounded atomic mass - number of protons)=6 So Carbon has 6 neutrons. Hope that is easy enough to understand.
It is 4.0026 : the atomic mass can be a fraction.
Roughly, subtract the atomic number (6) from it's atomic mass (12.01) and round to the nearest integer to get the average number of neutrons in a carbon sample, in this case 6.
krypton's atomic number is rounded to 84
Number of protons = atomic number Number of neutrons = Atomic Mass (rounded to the nearest whole number) minus the atomic number Number of electrons in a stable element = number of protons Number of electrons in an unstable element = atomic number minus the charge
Carbon has the atomic number of 6.
atomic mass of carbon=12 atomic number of carbon=6
When rounded to the nearest tenth the answer is 63.5When rounded to the nearest whole number, the answer is 64
503.8, when rounded to the nearest whole number, is 504.
right..... im not sure about it but since the atomic mass of zinc is 65.39 amu then most probably it will be 65 amu rounded to the nearest whole number. hope that helped :D
Carbon is a none metal element. atomic number of it is 6.
50.67 rounded to the nearest whole number is 51.
