What has the greatest electronegativity se s cl?
According to 'Little and Jones' scale Cl 2.83 Se 2.48 S 2.44
What is the atomic number of se?
The atomic number of Selenium is 34.
Which element has atomic weight of 79?
Selenium (Se) has an atomic weight of 79,04.
How does the ionization energy of Ne compare to that of Se?
Neon is a much smaller atom than selenium because neon has fewer occupied energy levels so it has a considerably smaller atomic radius. For that reason, it will be more difficult to remove an electron from Ne than Se, so Ne has the greater ionization energy.
What have the the smallest atomic radius Ge Se Br As?
Of the noble gases, helium has the smallest atomic radius. There are different ways to define atomic radius, and the different ways give different results so I will not attempt to present values for the radii of the inert gas atoms. Instead, I will point out a practical consequence of the small atomic radius of helium. Because of the small size of its atoms, helium diffuses out of common silicate minerals much more easily than do the other inert gases. J. M. Wampler, June 17, 2009
Rank these elements in terms of decreasing atomic radius?
Y (biggest) Fe Ga S F (smallest)
When the three elements se te and br ara arranged in order of increasing atomic radius?
Arranging Se, Te, and Br in order of increasing atomic size, you get: Br --> Se --> Te The trends are: atomic size increases right to left, and top to bottom.
Which is more reactive Br Se or Cl?
chlorine (Cl)
Which element has a larger ionic radius than calcium?
(Chlorine, Fluorine, anything that gains an electron when it ionizes) For example: when F becomes F−, it gains one electron but has the same number of protons, meaning the attraction of the protons to the electrons is weaker, creating a larger radius.
What elements has the largest energy out of Sb Pb Se Cl?
cl
What has the greatest electronegativity se s cl?
According to 'Little and Jones' scale Cl 2.83 Se 2.48 S 2.44
Which is more polar a sulfur-bromine (S-Br) bond or a selenium-chlorine (Se-Cl) bond?
Se-Cl bonds
What is the Lewis Structure for SeCN-?
.. .. .. :Cl - Se - Cl: .. .. .. There are two dots above the Cl, Se, and other Cl. There are also two dots below the Cl, Se, and other Cl. There are two dots to the left of Cl, and two dots to the right of the other Cl. The dash (-) represents two dots. So, there are a total of 20 electrons. Se has 6, and each chlorine has 7. 6 + 7(2) = 20
Would the Br ion be bigger than the Se ion?
No. The Se ion will be larger than the Br ion. The more negative the anion's charge, the larger the radius (more electrons = stronger repulsion between the electrons; so, more distance between them). Se would become "Se2-" as an anion, and Br would become "Br1-". Because Se's "2-" anion charge is more negative than Br's "1-" anion charge, and because Se would have more relative electrons to protons than Br, there is more repulsion between electrons, and distance, within the Se ion. So, the Se ion has a larger radius. Hope it helps.
Which is the most electronegative element Br Cl or Se?
O. Group 16
For which of the followings pairs of element can the atomic radii not be compared using the periodic table alone and why?
Cl is above and to the right of Se so Cl is smaller O is above and to the right of P so O is smaller Save P is above but to the left of SE- cannot compare using periodic table only ANSWER P AND O
How would you rank these atoms from smallest to largest atomic radius Cs K O Se?
The order is: O (60 pm), Se (115 pm), K (220 pm), Cs (260 pm); these are covalent radii after Slater.
