What is the rounded mass number of Argon?
Argon is a non metal element. Mass number of it is 40.
Can mass only be a whole number?
No, it cannot. A whole number is a quantity without units - a pure number. A mass of 1 pound is a whole number of pounds but it is 0.45359 kilograms: not a whole number, or 453.59 grams, again not a whole number.
Does the mass number of an element have to be a whole number?
Approximately, yes. But the mass number is an average of the masses of the isotopes of the element, weighted together according to their abundance. This averaging of different whole numbers results in the mass number not being a whole number.
What is the mass in kilograms of a sculpture that weighs 570 lb rounded to the nearest tenth?
570.0
What is the atomic mass rounded of boron?
Boron - B - Group IIIThe atomic number is 5.The mass number is 11.
What is 4.00260 rounded to in atomic mass?
It is 4.0026 : the atomic mass can be a fraction.
What is the molar mass of CO2 rounded to the nearest whole number?
The answer is simple it's one/1
What is the nearest whole number of atomic mass of potassium?
The nearest Whole number of atomic mass of potassium is 69
The mass number of an element is equal to what of an element?
The sum of the number of protons and the number of nuetrons.
What is zinc atomic weight to nearest whole number?
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
What is the mass of an element?
The mass number of an element is the atomic mass rounded to the nearest whole number. For Example, if the atomic mass is 54.94 (Manganese [Mn]), then the mass number will be 55. You can use the mass number to calculate the amount of neutrons in an isotope.
What element has an atomic mass of 32.06?
Sulfur- Element Number 16 on the Periodic Table of Elements
Why are atomic masses rounded?
Sometimes the atomic mass is listed as the average mass of the isotopes and contains a decimal. But since you can't have a fractional part of a proton or a neutron without creating a big mess, it is necessary to round to the nearest whole number. Subtracting the atomic number from the rounded atomic mass will give you the number of neutrons.
How can you figure out how many neutrons are in an atoms nucleus by using the atomic number and the atomic mass?
The atomic mass (rounded to the nearest whole number) is the number of nucleons - i.e. protons+neutrons. The atomic number is just the number of protons. So the difference between the two (mass minus number) tells you the number of neutrons.
What is the molar mass of H2O to the nearest whole number?
18g/mol
How do you get the number of protons electrons and neutrons from the atomic mass number and atomic number?
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 number of neutrons are equal to to the?
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.
