What else can I help you with?
Which is more polar a sulfur-bromine (S-Br) bond or a selenium-chlorine (Se-Cl) bond?
Se-Cl bonds
Which is the most electronegative element Br Cl or Se?
The most electronegative element is Cl (Chlorine), followed by Br (Bromine) and then Se (Selenium). Electronegativity measures an atom's ability to attract electrons towards itself in a chemical bond.
What elements has the largest energy out of Sb Pb Se Cl?
Cl has the largest energy as it is a halogen with the highest electronegativity among the elements listed, making it highly reactive and likely to form bonds with other elements to achieve a stable electron configuration.
Which letter represents the nonmetals on the periodic table?
Nonmetals on the periodic table are typically represented by the letter "H", "C", "N", "O", "P", "S", "Se", "F", "Cl", "Br", and "I".
What is the empirical formula for 1.443 g Se 5.841g Br?
To find the empirical formula, you need to convert the given masses of Se and Br into moles. 1.443 g Se is 0.018 moles Se, and 5.841 g Br is 0.036 moles Br. Next, divide the moles of each element by the smallest number of moles to obtain the simplest whole-number ratio. Thus, the empirical formula is SeBr2.

Se-Cl bonds

The most electronegative element is Cl (Chlorine), followed by Br (Bromine) and then Se (Selenium). Electronegativity measures an atom's ability to attract electrons towards itself in a chemical bond.
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.

How can you distinguish a metal with non metal with simple physical method?
Nonmetals are gases (Cl, Ar, N...), liquids (Br) or solids brittle and with a very low hardness (S, P, Se..).
What element is not nonmetal?
C, H, Se, Br, I, F, Cl, O, P, S, He, Ne, Ar, Kr, Rn
What has the greatest electronegativity se s cl?
According to 'Little and Jones' scale Cl 2.83 Se 2.48 S 2.44
Why is the ionization energy of br lower than that of cl but higher than that of se?
The ionization energy of an element is influenced by its atomic structure and the ease with which electrons can be removed. Bromine (Br) has a higher ionization energy than chlorine (Cl) because it is located further away from the nucleus, resulting in less shielding and higher attraction for its outermost electron. Selenium (Se) has a lower ionization energy than bromine because it is in a higher energy level, making its outermost electron easier to remove.
Does selenium have more in common with sulfur or bromine?
Selenium is more in common with Sulfur because they are in the same group. They have the same number of valence electrons and the only elements Selenium is related to is Sulfur and Tellurium. Anna C.
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
