May 29, 2020 · The atomic number is the number of protons. Therefore, you can subtract the atomic number from the mass number to find the number of neutrons. For example, Carbon’s atomic number/number of protons is 6 and the mass number is 12.011. This means there are 6 neutrons (approximately).
Numbers are displayed in scientific notation in the amount of significant figures you specify. For easier readability, numbers between 1,000 and -1,000 will not be in scientific notation but will still have the same precision. You may change the number of significant figures displayed by changing the number in the box above.
The calculator will find the critical points, local and absolute (global) maxima and minima of the single variable function. The interval can be specified.

2.21 (a) Define atomic number and mass number. Atomic number represents the # of protons in an atom. Atomic mass number is the sum total of protons and neutrons in an atom. (b) Which of these can vary without changing the identity of the element? Atomic mass # varies with neutron count, but the identity of the atom remains the same.
It is usual to characterize different isotopes by giving the sum of the number of protons and neutrons in the nucleus—a quantity called the atomic mass number.In the above example, the first atom would be called carbon-12 or 12 C (because it has six protons and six neutrons), while the second would be carbon-14 or 14 C.
Apr 16, 2020 · To calculate the mass of a specific number of atoms of an element, divide the number of atoms by 6.02 x 1023 and then multiply by the molar mass of the element. The process for calculating mass from the number of atoms is the same for all elements. Step 1: Calculate the number of moles from the number of atoms.
Learn the definition of "atomic number," see examples of atomic numbers of elements, and take a look at the shorthand notation for The atomic number identifies the number of protons in an atom.
