You are given Avogadro's number of atoms of a gas X. if half of the atoms are converted into X^(+)(g) by energy DeltaH , then ionisation enthaly of X is-

You are given Avogadro's no . Of X atoms . If half of the atoms of X transfer one electron to the other half of X atoms 409 kJ must be added . If these X^- ions are subsequently converted to X^+ , and additional 733k J must be added . Calculate IP and EA of X in eV Uses (1 eV = 1. 602 xx 10^(-19) J and N_a = 6. 023 xx 10^(23)) .

If N_A is Avogadro's number, then the number of hydrogen atoms in one g-equivalent of hydrogen is :

If Avogadro's number is A_(0) the number of sulphur atoms present in 200mL of 1N H_(2) SO_(4) is

The IE_(1) of Cs is 376 kj/mole . The number of Cs atoms that can be converted to Cs^(+) ions by 1J energy is

Metals have few electrons in their valence shell while non-metals generally have more electrons in their valence shell. Metallic character is closely related to atomic radius and ionisation enthalpy. Metallic character increases from top to bottom in a group and decreases from let to right in a period of periodic table. metallic character is inversely related to electronegativity of element. Q. 3 N_0//2 atoms of X_((g)) are converted it into X_((g))^(+) by energy E_(1) , 2 N_0//3 atoms of X_((g)) are converted it into X_((g))^(-) by energy E_(2) . hence, ionisation potential and electron affinity of X_((g)) are: ( N_(0) =Avogadro's number)

If N_(A) is Avogadro's number, then the number of oxygen atom in one g-equivalent of oxygen is
