The arrangement of electrons in an atom is called?
A unit of matter, the smallest unit of an element, having all the characteristics of that element and consisting of a dense, central, positively charged nucleus surrounded by a system of electrons. The entire structure has an approximate diameter of 10 -8 centimeter and characteristically remains undivided in chemical reactions except for limited removal, transfer, or exchange of certain electrons.
What arethe limitations of photoelectric effect?
I think that it is impossible for a massless body to move an electron from its path. Photons are massless but how they are able to displace an electron having mass.
An element is selective in the frequency of light it will absorb This selectivity is due to its?
Every element can only absorb certain wavelengths of light because of how the electrons are positioned around the nucleus. There is a fixed number of energy levels that each electron may move to, and each move will only occur if a specific amount of energy is absorbed. Thus each element, having differing electron orbital states can only absorb certain frequencies of light.
If energy is taken away from matter what will happen?
Then the matter will end up having less energy.Then the matter will end up having less energy.Then the matter will end up having less energy.Then the matter will end up having less energy.
When did Louis de broglie discover electron waves?
Wavelength is inversely proportional to momentum (of a particle such as an electron - or any having mass) was proposed by LDB for his doctoral thesis in 1924
General electronic configuration of group having low ionisation energy?
The general electron configuration of the group having the lowest ionization energy is [Noble gas configuration]xs1. In this case, x is the principal quantum number of the valance electron. The noble gas configuration may either be written out in full or denoted by the noble gas' atomic symbol in brackets (ie [Ne]).
What is inert gas configuration?
having 8 electron in the outermost shell or in valence shell....
What electron configuration represents an atom having the greatest nuclear charge?
choice 4
Why the metal is very reactive?
Metals , generally, have electronic configuration: with outermost electron having 1,2 or 3. Since, they can easily attain noble gas configuration to attain stability; they readily loose electron.
What is the electron configuration called that has 18 electrons in the outer energy level?
Noble gasAn atom's atomic number tells us its number of protons and electrons. Checking the periodic table for the element having an atomic number of 18, we find that it is argon. Argon's electron configuration is 1s2 2s2 2p6 3s2 3p6, which has all of its energy levels filled.
Why is the first ionization energy of arsenic is greater than the first ionization energy of germanium because?
There's two ways to answer this question. First electron configurations with half-filled sublevels are more stable then electron configurations that don't have half-filled sublevels. Since Selenium is one elctron away from achieving a more stable half-filled sublevel configuration it more readily gives up it's outermost electron, so less energy is requires to remove the outermost electron. Arsenic already has the stable configuration of half-filled sublevel so it wouldn't give up it's electron as readily, so more energy is required to remove it. Another way to look at it is that Selenium's outermost electron is in a p orbital that already has an electron so there is electron electron repulsion present in that orbital so it's attraction to the nucleus is less which is why less energy is required to remove it so the ionization energy is less. Arsenic has it's outermost electron unpaired in the p orbital so there is no electron electron repulsion present in that orbital so more energy is required to remove it then for Selenium's outer most electron. Hope this helps!
Ion electron configuration for beryllium?
Group 2 = 2 valance electons. Row 2 = Second energy level. = 1s2, 2s2. Confirm this with Beryllium being the fourth element and having four electrons - check.

How do electron configuration of noble gases give them shared properties?
The reason for the noble gases gases' electron configurations to allow them to have a similar property of having a low reactivity is because they all have a full set of electrons in their outermost energy level.
How many electrons are in the third level of magnesium?
3 levels (shells) which contain 2,8,2 electrons.
What is the electron configuration for N7?
1s22s22p3
How many electron shells does the beryllium atom have?
Two energy shells. Made up as 1s2, 2s2 Shells 1 & 2 each have only 's' orbital and each orbital has only two electrons in it. The outer shell '2' is more energetic. The electrons are paired and spin in opposite directions to each other.
