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.

∙ 11y agoThe Atomic Mass is equivalent to the sum of the number of protons and neutrons of an atom. If the atomic mass is known along with the number of neutrons, the number of electrons can be calculated as it similar to that of protons.

The atomic number of an element is the number of?
Is the number of protons or electron found in a given (neutral) element.
In the modern quantum based atomic theory what is the name given to a particular space around the nucleus in which an electron moves?
The name given to a particular space around the nucleus in which an electron moves is Orbital
Determine the number of protons?
The number of protons is equal to atomic number and the number of electrons (for a neutral atom).
The elements in Period 5 on the Periodic Table are arranged from left to right in order of?
Elements are arranged in order of their Proton Number/Electron Number. they are NOT arranged in Atomic Mass , because a given element my have isotopes, which alters the Atomic Mass.
What is this electron configuration 1s22s22p63s23p64s23d104p6?
Phosphorus To determine an element from its electron configuration, simply add up the superscript numbers (those are the numbers of electrons in each sublevel): 1s22s22p63s23p3: 2+2+6+2+3=15, and find the element with the matching atomic number*. In this case, Phosphorus. *Note: This method is not correct if the electron configuration of an ion is given, as the number of electrons in an ion does not match its atomic number.
What name is given to a region of an electron probability density graph where the probability of finding the electron is zero?
The region of zero electron density is called a "node."
Density is used to determine all what except what?
Density can be used to determine the mass and the volume of a given solid.
How do you find the volume and density if only the mass was given?
You cannot. You can determine the third variable if two are given but not determine two when given only one. You have to find some other way to first determine volume or density.
What is The outermost ring of electrons in an atom?
"Electron cloud" is the name given to the electrons which surrounds the atomic nucleus.
The atomic number of an element is the number of?
Is the number of protons or electron found in a given (neutral) element.
In the modern quantum-based atomic theory what is the name given to a particular space around the nucleus in which an electron moves?
The name given to a particular space around the nucleus in which an electron moves is Orbital
What is the name given to a particular space around the nucleus in which an electron moves in the modern quantum-based atomic theory?
The name given to a particular space around the nucleus in which an electron moves is Orbital
In the modern quantum based atomic theory what is the name given to a particular space around the nucleus in which an electron moves?
The name given to a particular space around the nucleus in which an electron moves is Orbital
Is the electron shell a path for the electron?
Shell is only Imaginary path made by rotating of the electron. A more common concept is that the shell or shape of the various orbitals is a probability density function for the election. That means it defines the locations that you are most likely to find the electron at any given time. These can also be shown as orbits these shells can also help u determine the electronic configuration
How can you determine which isotope of a given atom is the most common?
round the atomic weight to the nearest whole number.
How do you find mass and density of the gas cylinder?
That all depends on the type of gas and volume given for the problem. We can't determine the mass and density of the gas cylinder if we are not given these info, which can also include pressure (because density varies based on that variable).
Ion that have 41 proton and 39 electron?
It will be Nb2+ or Niobium(II) ion, as the atomic number of niobium is 41. (Note: Initially molybdenum was given as the answer. But the atomic number of Mo is 42 and not 42).
