The mass of Avogadro's number of Carbon-12 atoms, which exactly equals 12.000
What else can I help you with?
what is the universal standard is the basic of the atomic mass unit?
The mass of Avogadro's number of Carbon-12 atoms, which exactly equals 12.000
What is the atomic mass number of an isotope with atomic number 5 and includes 6 neutrons?
Basic arithmetic (5+6) suggests that the atomic mass is eleven.
What would the mass of an atom with 6 protons 6neutrons and 6 electrons be?
This is Carbon-12 (12C) it has a mass of exactly 12 universal atomic mass units. It serves as the standard for the universal atomic mass scale.If you look up carbon on the periodic table, you will find that it says 12.011. This difference is because a small amount of carbon has a seventh neutron, which is averaged into the atomic weight given on a periodic table.
What is the unit of weight for elements?
The unit of weight for elements is typically measured in atomic mass units (amu) or grams. The atomic mass unit is defined as one twelfth of the mass of a carbon-12 atom.
The atomic mass equals what?
In science the basic unit is the atom which is composed of neutrons, protons, and electrons. Electrons are generally considered to small to count as part of the mass. Atomic mass is the sum of neutrons and protons. For example: Oxygen has 6 protons and, in its natural state, 6 neutrons. This means that its atomic mass is 12.
What is bigger the atomic mass or atomic number?
Atomic no.=no. of protons Atomic mass=no. of protons+no. of neutrons Hence, atomic mass is greater
What is the atomic mass-?
The atomic mass is the mass of a molecule, atomic particle or sub-atomic particle.
What is the atomic mass of the atom?
Atomic mass is a measure of mass, just like kilos and pounds. There are at least 118 different basic atoms in the universe, all with different masses. The atomic mass of an atom is roughly the combined amount of protons and neutrons in it's core. For example: The atomic mass of a standard Oxygen atom, which has 8 protons and 8 neutrons in its core, is 15.994u (roughly 16).
The mass of an atom usually expressed in atomic mass units is its?
Atomic mass
What is the atomic mass of silver?
The atomic mass (or weight) of silver is 107.8682 amu (atomic mass units)
What is the atomic mass of aluminum?
The atomic mass number of aluminum is 27. The atomic mass of aluminum is 26.98115386
Which has the lower atomic mass cobalt or nickel?
Cobalt has an atomic mass of 58.933195(5) while nickel has an atomic mass of 58.6934(4). Nickel has the lower atomic mass.
