英文字典中文字典相关资料:


  • Are binary molecular compounds generally composed of a metal and a . . .
    No - generally nonmetals The words "molecular compound" implies the compound is held together by covalent bonds (chemical bonds sharing of electrons) Ionic compounds, on the other hand, are composed of ions that interact with each other through + - interactions (something analogous to the N end of a magnet "sticking" to the S end of a magnet) Binary Molecular Compounds are covalently
  • What does the size of an ion mean? And why does it affect . . . - Socratic
    The physical dimension of the atom (radius or diameter) Smaller-sized ions mean that the effect of the protons on the electrons is stronger (less distance between the charges) That in turn means that it is a stronger bond
  • What is the valence shell and how many valence electrons do the non . . .
    Non-metals have #4-8# valence electrons Group 14: 4 valence electrons Group 15: 5 valence electrons Group 16: 6 valence electrons
  • Question #b4e7a + Example - Socratic
    It is Ionic Bonding The Ionic Bonding is when a non-metal and a metal react together to form ions, so, metals lose electrons and nonmetals gain electrons Extra Example:- The common example of Ionic Bonding is Sodium Chloride (NaCl) which we call "the table salt" In this, the metal sodium loses 1 electron and the nonmetal chlorine gains 1 electron The sodium becomes positive ion because
  • What is the formula of magnesium nitride, Mg_3N_2? - Socratic
    Consider the typical valencies of magnesium metal and dinitrogen in their compounds Magnesium is a Group 2 metal with 2 valence electrons that can be oxidized: Mg rarr Mg^(2+) + 2e^- Dinitrogen is a gaseous non-metal that can be reduced to N^(3-): Each nitrogen ATOM has 5 valence electrons, and this configuration can be reduced to N^(3-) 1 2N_2(g) + 3e^(-)rarrN^(3-) Since typically non
  • Diamonds and graphite are two forms of what nonmetal?
    Diamond and graphite are made out of carbon atoms Diamond and graphite are made out of carbon atoms The difference between the two substance is the arrangement of the carbon atoms inside each one The arrangement of carbon atoms in diamond is tetrahedral and therefore the hybridization of carbon atoms is sp^3 Note that diamond is an insulator since it has no free electrons to conduct
  • What are electronegativity values? - Socratic
    Metals have some of the lowest electronegativities, so the electrons will not be held closely to the metallic atoms In a bond with a nonmetal that has a higher electronegativity, the electrons will be pulled much closer to the nonmetal leaving the metal effectively as a positive ion When metals are joined to other metals, metallic bonds are
  • How do you name MgCl_2? - Socratic
    Magnesium chloride Magnesium is in group II and will always form a 2+ ion when reacting Equally, chorine is I group VII and will tend to gain one electron from a metal to form a 1- ion MgCl_"2" is therefore the only possible formula for magnesium chloride Compare this to iron chloride Iron can form a 2+ or 3+ ion, therefore you must make a difference in naming FeCl_2= iron(II) chloride and
  • How could lithium metal reduce ferrous bromide to give iron metal . . .
    2Li + FeBr_2 rarr Fe + 2LiBr is the stoichiometric equation Fe(II) is reduced FeBr_2 +2e^(-) rarr Fe + 2Br^(-) (i) "Lithium metal" is oxidized Li rarr Li^+ + e^(-) (ii) We add (i) and (ii) together in such a way that the electrons are retired from the equation (i)+2xx(ii) 2Li +FeBr_2 +2e^(-)rarr 2Li^+ +Fe + 2Br^(-)+ 2e^(-) To give finally: 2Li +FeBr_2 rarr 2LiBr +Fe Both charge
  • Please solve q 39? - Socratic
    The answer is option (3) The equivalent weight of metal is ="mass of metal " "mass of hydrogen " xx1 008 The mass of metal =1 2 g Volume of hydrogen is =1 12l " at NTP" Mass of hydrogen is = " Volume of hydrogen at NTP (ml)" xx 0 000089 =1 12xx1000xx0 000089 =0 0997 The equivalent of the metal is =2 0 0997xx1 008 =20 2g The answer is option (3)
