Why is the electron affinity for clorine is greater than the electron affinity for iodine?
Generally electron affinity goes up as you go from left to right across the periodic table, and decreases as you go down a column. However, fluorine is an exception -- and the element with the highest electron affinity is chlorine.(Note that the most electronegative element is fluorine however; 'electronegativity' is not exactly the same as 'electron affinity'.)Electronegativity is the ability of an atom in a molecule to draw bonding electrons to itselfElectron affinity is a measure of the energy change when an electron is added to a neutral atom to form a negative ion.The reason that the electron affinity is not as high as might otherwise be predicted for fluorine, is that it is an extremely small atom, and so it's electron density is very high. Adding an additional electron is therefore not quite as favorable as for an element like chlorine where the electron density is slightly lower (due to electron-electron repulsion between the added electron and the other electrons in the electron cloud).
Which element has the electron configuration 1s22s22p63s23p5?
Cl
How many valence electrons does ch2cl2 have?
Cl2 is the diatomic molecule of chlorine (Cl) . It has 14 valence electrons, 7 in each atom. When chlorine forms a chloride ion, an atom accepts an electron and becomes Cl- (negative ion).
The electron dot structure for Cl?
There are 3 shells. The first containing 2 electrons then the second containing 8 electrons and the third(the valence shell) containing 7. In total it has 17 electrons. This should help:
How many L equals cL?
1 cL = 0.01 L 1 L = 100 cL cL = centilitres L = litres
What has the greatest electron affinity?
Cl and F
Who can help me with this problem Rank the following elements by electron affinity from most positive to most negative I have the elements Ar Cl O Sb and Rb?
The order is: O, Cl, Sb, Rb, Ar.
Which element has the lowest electron affinity Is it nitrogen?
No, nitrogen does not have a low electron affinity. Electron affinity increases as you go up and to the right on the periodic table. Thus, Groups I and II elements (ex. Cs, Ba, Sr, etc.) have LOW electron affinities and the halogens in Group VII (Br, Cl, F, etc) have the HIGHEST electron affinities. Chlorine has the HIGHEST electron affinity on the periodic table.(Fluorine is an exception in this case.)
What element has the most negative electron affinity Al Si S Cl?
The element with the greatest electronegativity in this scenario would be Cl or Chlorine.
What elements has the largest electron affinity?
AnswerElectron affinity is the energy released when we add an electron to the outermost orbit of the atom. Halogens are the higher in electron affinity, and chlorine has the higher electron affinity than rest of the halogens. The irregularity in the electron affinity trend between Cl and F is due to the small size of the F atom. Although F definitely has a higher attraction for an electron than Cl (as evidenced by its high electro negativity value), the small size of the F atom means that adding an electron creates significant repulsion. Since electron affinity is an energy measurement, the total energy associated with electron affinity winds up being the energy that is released by the electron binding to the nucleus, minus the energy involved in overcoming the electrical repulsion in the outer shell.This makes the fluoride anion so formed unstable due to a very high charge/mass ratio. Also, fluorine has no d electrons which limits its atomic size. As a result, fluorine has an electron affinity less than that of chlorine.
Why does electron affinity increase going left to right?
In general, electron affinity does not increase steadily from left to right. Firstly, only non-metals have electron affinities greater than 0. Secondly, the ordering of these electron affinities is O<N<F; S<P<Cl
Do Cl nd Ar have the same electron configuration?
No. No two elements have the same electron configuration.
Does F and Cl elements have the same valence electron configuration?
yes
What has the highest and lowest electron affinity Na Mg Al Si P S Cl Ar?
Chlorine and Argon respectively.
What is the relationship between the ionization energy of a mono anion such as Cl and the electron affinity of the neutral atom?
This quantities have the same magnitude but opposite sign.
How do sodium and chlorine combine?
Ionically. Sodium ionises its one outer most valence electon to form the cation Na^(+) Chlorine has electron affinity, wi thspace to accept one more electron to complete its outer energy shell octet. Cl^(-) Since the sodium cation and the chloride anion each have one opposite charge, they combine like the north and south poles of a magnet. Here are the equations Na => Na^(+) + e^- (ionisation) e^- + Cl => Cl^(-) (electron affinity) Na^(+) + Cl^(-) = (Na^+Cl^-) or just NaCl(s) (ionic attraction)
Is F more active than Cl?
They are both from the same group, yes. But F is above Cl so it means that the F's valence shell is nearer the nucleus (or at "lower level") than the valence shell in Cl, which causes F to have more effective nuclear charge. This fact explains the more electron affinity* in F in relation to Cl and therefore F is more reactive. * - electron affinity refers to a free atom. electronegativity refers to an atom in a molecule.
