What is the ratio of atoms?
A chemical formula gives the number ratio of the different kinds of atoms present in the compound. This means that the ratios are the same if you count in individual atoms, dozens of atoms, or molecules of atoms.
How big would it be if you had a googolplex of atoms?
There are fewer than a googol atoms in the known universe so a googolplex atoms would be outrageously huge.
How does electronegativity affect the molecular structure?
Do to unequal distribution of electronic cloud between two atoms, the both atoms acquire a partial positive atoms, the both atoms acquire a partial positive and negative charge resperctively.
What ratio of atoms are in NaCI?
It is 1:1 - the same number of atoms of Na and Cl.
How many atoms are there to the nearest 100?
The number of atoms cannot be estimated to that degree of accuracy.
One indicator that electrons in atoms are limited to specific energy levels is that?
light emitted from excited atoms occurs only at specific wavelengths
Powerful energy emitted from certain heavy atoms?
Radiation
The atoms that make up a star can be determined by?
Spectroscopic analysis of the light emitted by the star.
Energy of the red light emitted by a neon atoms with a wavelength of 703.2 nm?
jl
Imaging technique that detects the energy emitted by hydrogen atoms in a magnetic field?
MRI
The specific pattern of colors emitted by excited atoms is called a?
'Spectrum'.
What causes photons to be emitted from excited atoms?
The energy difference, between two energy levels, is emitted as a photon, when the electron "falls down" to a lower energy level.
What kind of energy will release when nuclei of atoms combine or split?
Fission, the splitting of atoms, and fusion, the combination of atoms, both produce generally the same kinds of energy. Some of the energy comes off as heat. The heated objects are the atoms involved and the alpha or beta particles emitted. The heat in this case can also be viewed as kinetic energy, indicating the speed of the particles. So this energy can be regarded as kinetic or thermal - at the sizes of object we are dealing with here, there is not much difference. Some of the energy is emitted as gamma rays, which are highly energetic photons. This is electromagnetic energy.
What does a beam of electrons emitted from an electron microscope show?
Atoms always occur in a variety of patterns.
What is the name of an imaging technique that detects the energy emitted by hydrogen atoms is a magnetic fields?
MRI
What does the intensity of an emission line depend on?
The intensity of a line is proportional to the number of photons emitted or absorbed by the atoms. It depends on the number of atoms giving rise to the line.
How many different protons of radiation were emitted from excited helium atoms to form the spectrum?
six photons
