Which of these elements has the least attraction for electrons ina chemical bond?(1) oxygen (3) nitrogen(2) fluorine (4) chlorin
2 answers:
The element which gas least attraction for the electrons in chemical bond is.
Further explanation:
Electronegativity:
It is defined as the tendency of an atom to attract the shared electrons in the bond towards itself is known as electronegativity. The more electronegative atom will more attract the bonding electrons towards itself than the less electronegative one. Therefore the electrons will spend more time with the more electronegative atom than an electropositive atom. The electronegative atom will acquire the partial negative charge, and the electropositive atom will acquire a partial positive charge.
Higher the electronegativity value of the element more will be its tendency to accept an electron towards itself.
Electronegativity trends in the periodic table:
<em>Along the period</em>, electronegativity increases due to the increase in the nuclear charge. This results in the strong attraction of electrons.
<em>Down the group</em>, electronegativity decreases due to an increase in the size of elements. This results in lesser attraction between the nucleus and the electron.
The given elements fluorine, oxygen, nitrogen, are present in the same period of the periodic table. Since along the periods the electronegativity decreases, therefore, the order of electronegativity is N<O<F. Among these electronegative elements, nitrogen is an atom with least the electronegativity value.
In the given elements chlorine and fluorine, chlorine has less electronegative value because down the group electronegativity decreases.
Therefore we have two atoms, nitrogen, and chlorine which have lesser electronegative value. Now both nitrogen and chlorine have nearly the same electronegativity value, but since chlorine is larger in size thus its electron is more loosely held by the nucleus. Therefore, the element which gas least attraction for the electrons in chemical bond is chlorine.

Answer : The final equilibrium temperature of the water and iron is, 537.12 K
Explanation :
In this problem we assumed that heat given by the hot body is equal to the heat taken by the cold body.
where,
= specific heat of iron = 560 J/(kg.K)
= specific heat of water = 4186 J/(kg.K)
= mass of iron = 825 g
= mass of water = 40 g
= final temperature of water and iron = ?
= initial temperature of iron =
= initial temperature of water =
Now put all the given values in the above formula, we get:
Therefore, the final equilibrium temperature of the water and iron is, 537.12 K
