 The electron configuration of nitrogen is 1s2 2s2 2p3 .What does the 3 in 2p3 mean ?


Answer:
The electron configuration of nitrogen is 1s2 2s2 2p3 .The 3 in 2p3 means that there are three electrons in 2p.Now 2p means that p is the sub shell  of second orbit of nitrogen atom.Remember that p sub shell is divided into three parts that are called orbitals.So there are three orbitals in p subshell.These orbitals are pₓ ,py , and pz .Remember that each orbital can hold maximum two electrons.

More specifically,The electron configuration of nitrogen is 1s2 2s2 2p3 .The 3 in 2p3 means that there are three electrons in 2p subshell of second orbit of nitrogen.

Selenium has six valence electrons. Read:CO2 Lewis Structure Explanation: Now I am going to show you how to find valence electrons in selenium  in just 5 steps. Add caption              Step-1: First, find the atomic number of  selenium  from periodic table. From periodic table ,we see that the atomic number of  selenium  is 34.                  Step-2: We know that the atomic number of  selenium  is 34.So  selenium  has 34 protons and 34 electrons as the charge of electrons and protons are equal but opposite in nature.The charge of proton is +1 and the charge of electron is -1. Read:CO2 Lewis Structure                 Step-3: Now write the electron configuration of  selenium   . Se(34)=1s²2s²2p⁶3s²3p⁶4s²3d¹º4p⁴ Rewrite this ...

【】How to Convert Ethene to Ethanoic Acid or Acetic Acid||How Ethanoic Acid Is Prepared from Ethene

Image
Answer: To convert ethene to ethanoic acid,we will adopt four steps:              Step-1: Ethene reacts with HBr and we get 1-bromo ethane.            Step-2: 1-bromo ethane reacts with aqueous KOH and we get ethanol.            Step-3: Ethanol is oxidized by K₂Cr₂O₇ plus H₂SO₄ and we get ethanal.            Step-4: Again,ethanal is oxidized by K₂Cr₂O₇ plus H₂SO₄ and we get ethanoic acid or acetic acid. Now see all the steps at a glance.

How to Convert Propyne to Propene Propyne reacts with hydrogen (H₂) in presence of  Pd and BaSO₄ at 25ºc temperature and produce propene(CH₃-CH=CH₂). Here BaSO4 acts as catalyst poison towards Pd catalyst reducing it's catalytic action and controls the upto first stage. How to Convert Propene to Propyne          Step-1: Propene(CH₃-CH=CH₂) reacts with Br₂ in presence of CCl₄ and produce 1,2-dibromo propane( CH₃-CH(Br)CH₂Br).             Step-2: 1,2-dibromo propane( CH₃-CH(Br)CH₂Br) reacts with (alc)KOH and produce 1-bromo propene-1(CH₃-CH=CH-Br).                        Step-3: 1-bromo propene-1(CH₃-CH=CH-Br) reacts with sodamide and produce propyne.

SO2 Lewis Structure   Answer: Here is the definition of SO2 Lewis structure. SO2 Lewis structure (sulfur dioxide electron dot structure) is that type of diagram where we show the total 18 valence electrons of SO2 as dots , or dots and dashes(-).In Lewis structure,it is common that a bonding pair of two electrons can be shown by  dash(-) or dots(●●) but a lone pair of two electrons is shown by dots[●●]. In SO2 Lewis structure,there are two double bonds that are going from the atom sulphur to oxygens. In SO2 Lewis structure ,there are totally five lone pairs of electrons.The each  oxygen has two lone pairs of electrons and the sulphur atom has one lone pair of electrons. In SO2 Lewis structure ,the oxygen atoms follow the octet rule but the sulfur atom don't follow the octet rule.It has more than eight electrons. In SO2 Lewis structure,we get nine pairs of electrons.Out of nine pairs of electrons,SO2 has four bond pairs of electrons and five lone pairs of electron...
