What are three examples of elements with unpredictable electron configurations?
Copper and Chromium have 1 electron in the 4s subshell, and 5 and 10 in the 3d subshell respectively. You needn't know beyond that until University.
How many electron in external shell of vanadium element?
Two electrons are in the external shell of vanadium.
What is the electron configuration for W?
1 s 2 2 s 2 2 p 6 3 s 2 3 p 6 3 d 10 4 s 2 4 p 6 4 d 10 4 f 14 5 s 2 5 p 6 5 d 4 6 s 2 The link below disagrees with the above, group 6 elements are special. By the Aufbau principle I believe. It is is more stable to have one electron in each subshell than to have 2 electrons in the s subshell and 4 in the d subshell.
What is the valence shell for nitrogen?
Nitrogen (N) has atomic number 7. It has full 1s and 2s orbitals. The 2px orbital has 1 electron, the 2py orbital has 1 electron and the 2pz orbital has 1 electron. So the valence shell is: 2s2 - 2p3. It contains 5 electrons.
Number of electrons in each Electron configuration?
Period ---- Shell -------------- Atom pairs 1 ------------ s ---------------------- 1 2 ---------- s, p ------------------- 1, 3 3 ---------- s, p ------------------- 1, 3 4 -------- s, p, d ---------------- 1, 3, 5 5 -------- s, p, d ---------------- 1, 3, 5 Each pair represent 2 atoms. The s shell can hold 2 electrons, the p shell can hold 6 electrons, and the p shell can hold 10 electrons. The 3rd shell does not include the d shell since the atoms in the B group begin on the 3rd period There are also some special configurations in the B group where the s shell lends an electron to the d group such as Cr. For example, if Cr followed the general guidelines that other atoms in the A groups, it would be 1s^2/2s^2 p^6/3s^2 p^6/4s^2 d^5, except it actually is 1s^2...4s^1 d^5 Special guidelines apply to group 5B for period 5 excluding 4, group 6B for periods 4 and 5, group 8B (sub groups 8, 9, and 10) for period 5, and group 1B for periods 4 and 5 (and 6 if you want to count the f subshell), where electrons from the s shell are loaned to the d shell

Which subshell of chlorine have valence electron?
3s and 3p, remember Cl has 7 valance electron. 3s^2 and 3p^5
In a Bohr diagram how many electrons are in each shell?
There are 4 electron sub-shells: s, p, d, and f. These letters stand for sharp, principal, diffuse, and fundamental, but the names are not important. s subshells have 2 electons, while p subshells have 6, d subshells have 10, and f subshells have 14. There can be higher subshells, but these subshells require too much energy to fill and no element with a g subshell (the next subshell after f) has ever been synthesized. The first shell (i.e. the first period of the periodic table) has only s. Thus, the first shell has 2 electrons. The second shell has s and p subshells, so it has 2+6 or 8 electrons. The third shell has s, p, and d subshells. It ultimately has 18 electons. This can be misleading, however. The d subshell requires more energy to fill than the higher-shell s subshell. This is why the third period of the periodic table does not have a d section: the d electron subshell of the third Bohr shell does not fill until after the s subshell of the fourth Bohr shell has filled. Looking at the periodic table, you can see that the third period only has 8 electrons, while the 4th period has 18. The 18 electrons in the fourth period are the s subshell of the fourth shell, the d subshell of the 3rd shell, and the p subshell of the 4th shell. The fourth shell is similar to the third shell, but more extreme. The fourth shell has s, p, d, and f subshells, but the f subshell is not filled until two higher s shells have been filled. It does, however, fill out to 32 electrons in the 6th period of the periodic table. In the 6th period, the first period to have 32 electrons, there are 32 electrons, filling these subshells: s subshell of the 6th shell, f subshell of the 4th shell, d subshell of the 5th shell, and then the p subshell of the 6th shell. The fifth shell would ultimately fill out to a full 50 electrons and would do so in the 8th period of the periodic table. However, as previously noted, no substance has ever been found or generated with that many electrons. It would fill the s subshell of three shells above (i.e. shell 8) before it filled the g subshell of shell 5. No element in the 8th period has ever been synthesized, so a filled fifth Bohr shell has never been found. A good example for a Bohr diagram would be Astatine, which is in the 6th period. In the first shell of the Bohr diagram, you have 2 electrons (s subshell only). It is filled completely. In the second, you have 8 electrons (s and p subshells) and in the third you have 18 electrons (s, p, and d), and both shells are filled completely. In the fourth shell, you have 32 electrons (s, p, d, and f), and it is filled completely. In the fifth shell, you have 18 electrons. This is because only the s, p, and d subshells are filled. It would require too much energy to fill the f subshell of the 5th shell, so the electrons just go to the s, p, and d subshell of higher shells. The 6th shell has 7 electrons. The 2 electrons of the s subshell are filled first, and then 5 electrons go into the p shell.
Is bromine Paramagnetic or diamagnetic?
Bromine is paramagnetic. This is because the 4p subshell has a value of 4p5. 5 electrons in a p subshell (which has space for 6), means the last electron is unpaired. The unpaired electron gives it the property of paramagnetism. Alternatively, Selenium is diamagnetic, as it has the outer subshell 4p4, meaning no electrons are unpaired.
How many electron in the outermost shell of phosphorus?
5
Valence electron of fluorine?
Fluorine has 7 valence electrons. 2 In the first electron shell, and 5 in the second electron shell.
How many valence electrons do Halogens have in p subshell orbitals?
Halogens have 5 electrons in their outermost p shell in their electrically balanced state. The p shell has 3 orbitals in each energy level. Halogens have 2 filled orbitals each with 2 electrons in them and one orbital with only one electron in it. In order to obtain the stable noble gas electron configuration, halogens gain one electron to completely fill the p shell on the outermost energy level. This gives halogens a charge of -1.
How many electrons are in the outermost electron shell of a phosphorus atom?
5
How many unpaired electrons in (d) subshell in ferric Fe3?
5 unpaired electrons There are 5 unpaired electrons in the Fe3+ ion. The reason for this is that Iron has the electron configuration Ar3d5.
How many electron in external shell of vanadium element?
Two electrons are in the external shell of vanadium.
What is the most electronegative element and why?
Fluorine (F) is the most electronegative element because it has 5 electrons in it's 2p subshell. The optimal electron configuration of the 2p subshell has 6 electrons. Since F is close to this optimal configuration, electrons are highly attracted to the nucleus.
How many bonds does phosphorous form?
5, one for each electron in the outer shell
