What is the mass in atomic mass unit of one fluorine atom?
19.0
Average mass of one atom of an element?
what is the atomic mass of an element : atomic mass is equal to the number of protons and number of neutrons present in an element
What is the atomic number of an atom with 9 protons 10 neutrons and 9 electrons?
Only protons and neutrons have 1 unit mass each, which form the nucleus. The Electrons that orbit the nucleus are of negligable mass. Therefore; total mass = 9 protons + 10 neutrons = 19 unit mass.
What element has a gram atomic mass that is greater than the gram atomic mass of the element with an atomic number higher by one unit?
Both argon and cobalt have this characteristic.
Does a element have mass in it?
Yes, an element has mass. The smallest unit of an element is the atom, and the atom's mass is the amount of matter in it: the neutron(s), proton(s), and electron(s). Because the number of protons determines an element's identity, and protons have mass, elements always have mass (though this can be a tiny, almost immeasurable mass).
What is a group of symbols that show the kind and number of each element in a single unit of a molecule called?
Mass
What is the molar mass number of an element?
The unit for the atomic masses (and also for atomic weights) is the unified atomic mass unit equivalen to to 1/12 of the atomic mass of the carbon isotope carbon-12 in normal state or 1,660 538 921(73)×10−27 kg.
What is the atomic number of carbon 14?
Carbon is a non metal element. Atomic mass number of it is 12.
What is the atomic mass unit of Saturn?
Saturn is not the name of a chemical element and therefore does not have any atomic mass unit.
What is the definition for atomic mass?
so the mass of an atom is determined by the number of protons and neutrons in an element. For a given element, the number of protons is the same but the number of neutrons can vary (an element can have various isotopes). Therefore, the average atomic mass of an element is simply a weighted average of the masses of all the isotopes of that element. (a weighted average means that how common an isotope is is taken into account when incorporating it into the average, so rare isotopes will not count as much as common isotopes)
What is the atomic mass unit of Alluminium?
Aluminium is a meta element. Atomic mass of it is 27.
What does amu mean in the atomic mass of an element aside of it?
AMU= atomic mass unit
