The atomic radius can be determined by finding the density of a material because the density is related to the spacing between atoms in a solid material. By measuring the density and knowing the Atomic Mass of the material, scientists can calculate the volume occupied by each atom and thus determine the atomic radius.
What else can I help you with?
What is the atomicity of a gas if it's vapor density is 28 and atomic weight is 14?
The atomicity of a gas can be determined by comparing its vapor density to its atomic weight. In this case, if the vapor density is 28 and the atomic weight is 14, the atomicity of the gas is 2. This means that each molecule of the gas consists of 2 atoms.
What is density and theoretical density?
Density is a measure of how much mass is contained in a given volume. Theoretical density refers to the maximum possible density a material can have based on its crystal structure and atomic composition.
Work out the number of atoms per cm cubed from density?
To find the number of atoms per cm^3 from density, you first need to know the atomic mass of the material. Calculate the molar volume (cm^3/mol) using the molar mass of the material. Then convert to cm^3/atom by dividing by Avogadro's number (6.022 x 10^23). Finally, divide the material's density by the molar volume to get the number of atoms per cm^3.
How do you determine electron density given atomic density?
The electron density is simply deduced from the atomic density as follows : if ne denotes the electron density and na the atomic density then : ne= z na with z being the number of valence electron per atom.
What is The name and physical properties of an element is determined by?
The name and physical properties of an element are determined by its atomic structure, specifically the number of protons in its nucleus, which dictates its atomic number and unique identity. The arrangement of electrons around the nucleus further influences its chemical behavior and physical properties such as melting point, density, and color.
How do theoretical density different to density?
Theoretical density refers to the calculated density of a material based on its molecular structure and atomic weights. It is a theoretical prediction. Density, on the other hand, is the measurement of the mass of a material per unit volume. It is typically determined experimentally.
Is the atomic number of an element determined by its number?
Protons. This determines what material the element is.
What is the atomicity of a gas if it's vapor density is 28 and atomic weight is 14?
The atomicity of a gas can be determined by comparing its vapor density to its atomic weight. In this case, if the vapor density is 28 and the atomic weight is 14, the atomicity of the gas is 2. This means that each molecule of the gas consists of 2 atoms.
What is the closeness of atoms in an object called?
The closeness of atoms in an object is called atomic packing or atomic density. It refers to how closely atoms are packed together within a material, influencing its physical properties like density, strength, and conductivity.
Why is the krypton atomic mass not determined?
The relative atomic mass is 83.798. So where did you get that it is not determined.
What is density and theoretical density?
Density is a measure of how much mass is contained in a given volume. Theoretical density refers to the maximum possible density a material can have based on its crystal structure and atomic composition.
What causes the strength of a magnet?
The strength of a magnet is determined by the alignment and number of its magnetic domains, which are tiny atomic magnets within the material. Factors such as the material used, its atomic structure, and the presence of an external magnetic field can all affect the strength of a magnet.
How are electrons determined?
By subtracting the atomic mass and atomic number
Work out the number of atoms per cm cubed from density?
To find the number of atoms per cm^3 from density, you first need to know the atomic mass of the material. Calculate the molar volume (cm^3/mol) using the molar mass of the material. Then convert to cm^3/atom by dividing by Avogadro's number (6.022 x 10^23). Finally, divide the material's density by the molar volume to get the number of atoms per cm^3.
How were the atomic number and the atomic masses of the elements determined?
Atomic masses are determined by mass spectrometry. The atomic number is identic with the number of protons in the atom - depends on position in the periodic table.
How do you determine electron density given atomic density?
The electron density is simply deduced from the atomic density as follows : if ne denotes the electron density and na the atomic density then : ne= z na with z being the number of valence electron per atom.
The atomic number of an element is determined by the number of?
The atomic number of an element is determined by the number of protons within it's nucleus.
