【】When an atom loses an electron it becomes quizlet

when an atom loses an electron it becomes quizlet


◆Choose the answer.

A) Negative ion

B) Positive ion

C) Neutral

D)Nothing




Answer:

When an atom loses an electron,it becomes positive ion which is called cation.

You know that the charge of proton  is positive (+1) and the charge of electron is negative (+1).


Besides,we know that an atom is neutral because the number of proton and electron is in same number.

Now if one electron goes from the neutral atom,one proton of that atom will not be satisfied.Thus the neutral atom become positively charged.

H(1)=one proton and one electron=Neutral atom


H+(1)=one proton and zero electron=Positively charged hydrogen atom=Cation

So the charge of atom will be positive (+1) if it loses an electron and this positively charged ion is called cation.

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 from low to high value of n.

Sulfuric acid and Sodium hydroxide Hello,you are in right place to know about the reaction between sulfuric acid and sodium hydroxide. Sulfuric acid is an acid because it has hydrogen ion.The formula for sulfuric acid is H₂SO₄.It is a strong acid. Sodium hydroxide is a base because it has hydroxide ion.The chemical formula for sodium hydroxide is NaOH.It is a strong base. Read this:CO Lewis Structure Read:CO2 Lewis Structure                 Sulfuric acid(H2SO4) and Sodium hydroxide(NaOH)  Acid reacts with base to form salt and water.This type of reaction is called acid base neutralization reaction. In case of sulfuric acid and sodium hydroxide,acid-base neutralization reaction  will happen. Sulfuric acid reacts with sodium hydroxide and produce sodium sulphate(Na₂SO₄) and water(H₂O).Here  sodium sulphate(Na₂SO₄) is a salt beacause its positive part has come from base and negative part has come from acid.

【】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.

【 】SO2 Lewis Structure ,Valence Electrons ,Formal Charge,Polar or Nonpolar

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 electrons.Here,each oxy

【】 C6H12O6 Valence Electrons ||How many valence electrons are there in a glucose molecule

Image
  How many valence electrons does C6H12O6 (glucose) have ? Answer : In  C₆H₁₂O₆ ,we get 6 carbon atoms , 12 hydrogen atoms and 6 oxygen atoms. Firstly, carbon is an element of group 4A,so it has 4 valence electrons. Secondly,Hydrogen is an element of group 1A.So it has one valence electrons. Thirdly, oxygen is an element of group 6A .So it has six valence electrons. For   C₆H₁₂O₆ , 6 C = 6 × 4 = 24 12 H =12 × 1 =12 6 O = 6 ×6    = 36 Totally, we are getting 24 + 12 + 36 = 72 valence electrons in glucose (C6H12O6). Next
