This trick for element chlorine is applicable See, At no = 17 17×2+1=35 At mass number of Cl is 35.5 Means approximately equl to 35 I mean to say this element should not be included in BeNClr

@makkurosa5593 2 ай бұрын

according to the rules of rounding off numbers though, 35.5 should be rounded up to 36. So that’s why it’s part of the BeNClAr
