The Number Of Protons & Neutrons In An Atom.
mass number= no. of protons + no. of neutron
mass number = number of protons + number of neutrons DIFFERENT FROM ATOMIC MASS atomic mass = weighted average of all the isotopes of that element
To determine the atomic number of an element with a mass number of 22, you would need the number of protons in the nucleus. Since the mass number is the sum of protons and neutrons, subtracting the number of neutrons (mass number) from the mass number gives you the number of protons (atomic number).
To determine the number of moles in a substance, you can use the formula: moles mass / molar mass. Simply divide the mass of the substance by its molar mass to find the number of moles.
The mass number of an atom is determined by counting the total number of protons and neutrons in its nucleus. Electrons, which are much lighter than protons and neutrons, are not included in the mass number calculation.
Number of Neutrons = Mass number - Atomic Number
subtract the atomic number from the mass number
no --- atomic number
To determine the number of protons, look at the atomic number. The number of electrons is also the atomic number.To find the number of neutrons subtract the atomic number from the Atomic Mass number.
To determine the number of moles of solute in a solution, you can use the formula: moles mass of solute / molar mass of solute. This involves measuring the mass of the solute and knowing its molar mass, which is the mass of one mole of the substance. By dividing the mass of the solute by its molar mass, you can calculate the number of moles present in the solution.
To determine the mass number of nitrogen, you would need to know the number of protons and neutrons in its nucleus. Nitrogen has 7 protons, so the mass number can be calculated by adding the number of protons (7) to the number of neutrons in the nucleus.
No, the mass number of an element is the sum of protons and neutrons in the nucleus. To determine the number of electrons, you would need to know the atomic number of the element, which is equal to the number of protons. Electrons in a neutral atom equal the number of protons.
