If you know the mass of one mole of those atoms (the mass number listed on the Periodic Table), then you divide that number by Avogadro's constant: 6.022x10^23 which gives you the mass of one single atom
The Atomic Mass can be calculated by adding the mass of protons, neutrons, and electrons. Electrons essentially have no mass, and protons and neutrons have an atomic mass of one. So looking at a common element of oxygen with 8 protons, 8 neutrons, and 8 electrons, we can find the atomic mass to be 16 (the number of protons plus the number of neutrons). An isotope of oxygen having 8 protons, 7 neutrons, and 8 electrons, would have an atomic mass of 15.
Neon is a non meta element. Atomic mass of it is 20.
Atomic mass of an element measures the mass of that element on a molecular scale, taking into account neutrons and protons, which weigh approximately 1. Electrons are negated. Atomic mass is also the mass, in grams, of 1 mole of that element.
Nitrogen, element 7, has an atomic mass of 14.0067, rounded to 14.007.
Mercury has an atomic mass of 200.
Vanadium is the element that has an atomic weight of 50.942.
To calculate the atomic mass of an element, add up the mass of protons and nuetrons.
You need to know the atomic # or the masses of each isotope of the element.
The atomic mass of a substance is the mass of one mole of that substance. To calculate the atomic mass of 25 mg of a specific element, you would first need to determine the molar mass of that element. You can then use the molar mass to convert the mass of the sample (25 mg) to the number of moles, and then calculate the atomic mass of that amount.
To calculate the density of an element from the periodic table, you would need to know the element's atomic mass and atomic volume. The formula for density is mass divided by volume. You can find the atomic mass on the periodic table and calculate the volume using the element's atomic radius or other relevant data.
the atomic number of each isotope-apex;)
To calculate the number of neutrons in an element, you subtract the atomic number (number of protons) from the atomic mass (nearest whole number). The atomic mass is the weighted average of the isotopes of that element found in nature. For example, for carbon, the atomic number is 6 and the atomic mass is around 12, so the number of neutrons would be 12 - 6 = 6.
Number of neutrons = Atomic mass - Atomic number
To calculate the atomic mass of bromine, you would take the weighted average of the isotopic masses of bromine's isotopes, considering their relative abundance in nature. The atomic mass of bromine is approximately 79.904 u.
Number of protons
By taking the wieghted averages of naturally occurring isotopes of that element. :)
The atomic mass unit (amu) is a unit of mass used to express the average mass of an atom or molecule. To calculate the atomic mass unit of gold (Au), you would look at the atomic mass of gold on the periodic table, which is approximately 197 amu.
The atomic mass of an element is the weighted average mass of its isotopes. To determine the atomic mass of element F, you would need to know the abundance of each isotope and its individual atomic mass, and then calculate the weighted average based on those values.
