6. An atomic number is always a whole number, so it does not need rounding.
503.8 rounded to the nearest whole number is 504
51 to the nearest whole number.
atomic mass of carbon=12 atomic number of carbon=6
It is 5 rounded to the nearest whole number
It is then 72 when rounded to the nearest whole number
It is 4.0026 : the atomic mass can be a fraction.
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.
The atomic weight of zinc to the nearest whole number is 65.
Yes, the atomic mass on the periodic table is usually rounded to the nearest whole number, so an atomic mass of 30.97 would be rounded to 31.
You can determine the number of neutrons in an atom by subtracting the atomic number (number of protons) from the atomic mass (rounded to the nearest whole number). This will give you the number of neutrons in the atom.

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.
The atomic number of krypton is 36.
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
The atomic number for hydrogen is 1 and the atomic number for carbon is 6.
503.8 rounded to the nearest whole number is 504
Carbon is a none metal element. atomic number of it is 6.
