प्रश्न
How many atoms of each kind are present in the following molecules: calcium oxide, chlorine, water, carbon tetrachloride?
How many electrons are required by each atom mentioned in (a) to attain the nearest noble gas configuration?
उत्तर
a.
CaO- 1 calcium atom + 1 oxygen atom
Cl2 - 2 chlorine atoms
H2O - 2 hydrogen atoms + 1 oxygen atom
CCl4 - 1 carbon atom + 4 chlorine atoms
b.
Ca - will donate two electrons
O - will accept two electrons
Cl - will accept one electron, so two Cl atoms will share an electron pair.
C - will accept four electrons by sharing electrons pairs with hydrogen forming covalent bonds.
H - will donate one electron by sharing an electron pair with carbon.
