Popular questions
What element has 17 protons?
Chlorine (E925) has 17 protons; its atomic number is 17.
What element has 17 electrons?
A neutral chlorine atom has 17 electrons, matching its atomic number of 17.
Which element has 17 protons?
Chlorine—the element with atomic number 17—has 17 protons.
What element has 17 protons and 18 neutrons?
Chlorine‑35, an isotope of chlorine, has 17 protons and 18 neutrons and is its most abundant isotope.
What is the most active element in group 17?
Fluorine is the most reactive halogen in Group 17; chlorine is also highly reactive but less so than fluorine.
Is nitrosyl chloride polar?
Yes—NOCl is a polar molecule due to its bent geometry at nitrogen and the differing electronegativities of O and Cl, which produce a net dipole.
(b) in which species (no2cl or no3-) are the n-o bond(s) longer? nitrosyl chloride nitrate ion?
Longer in nitrate (NO3−): its N–O bonds have lower bond order (~1.33) than the N=O double bond in nitrosyl chloride, so they are longer.
How is nitrosyl chloride used?
As the additive E919 it was historically used as a flour treatment/bleaching agent, but this use is now largely discontinued and not authorized in the EU; today it is mainly an industrial chlorinating/nitrosating reagent rather than a common food additive.
Nitrosyl chloride nocl decomposes to nitric oxide and chlorine when heated answer l?
Yes—on heating, 2 NOCl → 2 NO + Cl2, and the decomposition is promoted by heat and light.
Question 6 what is the "axe" description of the nitrosyl chloride molecule?
AX2E1 at the nitrogen center (two bonded atoms and one lone pair), giving trigonal planar electron geometry and a bent molecular shape.
