What is the atomic number used for?
The atomic number of an element is the number of protons found in the nucleus of an atom. The atomic number is identical to the charge number of the nucleus. For example, the atomic number of Oxygen is 8.
What device can be used to make measurements globally?
The device that can be used to make measurements globally depends with what is being measured. The weighing scale for instance is used to measure the weight.
What is an aneometer?
An anemometer is a device used to measure the speed of the wind. It typically consists of cups or blades that spin in the wind, and the speed of rotation is used to calculate the wind speed. This instrument is commonly used in meteorology, aerodynamics, and environmental monitoring.
What is the formula mass for ammonium sulfate NH42SO4 which is used in the biochemical treatment of wastewater?
The formula mass of ammonium sulfate (NH4)2SO4 is calculated by adding the atomic masses of each element present in the compound. For (NH4)2SO4, the atomic masses are: N=14, H=1, S=32, O=16. Adding 2(N) + 8(H) + S + 4(O) gives a total formula mass of 132 g/mol.
What does an element's atomic number tell us?
An element's atomic number tells us the number of protons in an atom of that element. It is used to uniquely identify the element and determine its placement on the periodic table. The atomic number also corresponds to the number of electrons in a neutral atom of that element.
Can Atomic mass be used to determine molecular mass?
Yes, the accumulation of atomic masses of the atoms within a molecule is the molecule's molecular mass.
What nuclide is used as standard relative scale for atomic masses?
Carbon-12 is used as the standard relative scale for atomic masses. This is defined as having a mass of exactly 12 atomic mass units (u). Other elements are compared to this standard to determine their atomic masses.
Why interval notation cannot be used to represent the set of atomic masses given?
Why interval, notation cannot be used to represent instead of atomic masses
State the name and the mass of the isotope relative to which all atomic masses are measured?
The isotope used as the reference for atomic masses is carbon-12, with a mass of 12 atomic mass units (amu).
What nuclide is used as the standard in the relative scale for atomic masses and What is it's assigned atomic mass?
Carbon-12 (12C) is used as the standard in the relative scale for atomic masses, and its assigned atomic mass is 12 atomic mass units.
What is often used in place of atomic weights?
Relative atomic masses are often used in place of atomic weights. They represent the weighted average of the masses of the isotopes of an element relative to the mass of a carbon-12 atom.
Si units used for the masses of atomic particles?
The atomic mass unit (u) or unified atomic mass unit (amu) is the standard unit used to measure the masses of atomic particles such as protons, neutrons, and electrons. 1 atomic mass unit is defined as 1/12th of the mass of a single carbon-12 atom.
What are Binary stars used to determine?
The masses of the two stars.
Is this statement true or false The isotope hydrogen-1 is the standard used for the relative scale of atomic masses?
True. Hydrogen-1, also known as protium, is the standard used for the relative scale of atomic masses. Its mass is defined as exactly 1 atomic mass unit (amu) on the atomic mass scale.
Why is the relative atomic mass of an element relative to carbon-12?
The relative atomic mass of an element is compared to carbon-12 because carbon-12 is used as a standard reference point for measuring atomic masses. This comparison helps scientists determine the mass of atoms of different elements in relation to each other.
Identify the unit that is used for atomic masses?
The carbon atom, which has six protons and six neutrons, is arbitraily declared to have an atomic weight of 12.
