How does ionisation potential vary in a period and in a group?

Moving left to right within a period or upward within a group, the first ionization energy generally increases. Ionization energy increases from left to right in a period and decreases from...

Highest atomic radius has Francium. The nobel gases have the highest ionisation enthalpy. Halogens have high value of electron gain enthalpy. Florine has highest electronegativity.

First: Ba -> Ba1+ + e- = 502.8 kJ/mol Second: Ba1+ -> Ba2+ + e- = 965.1 kJ/mol

Ionization energy increases from left to right within a period. Noble Gases have a very stable electron configuration, therefore, they have the highest amount of ionization energy within their periods....

Ionization energy is increased in the periodic table from the left to right. It depends on the number of electrons, which element needs to the electronegative condition. So, the greater...

Solution. Regardless of the nature of the strong base and strong acid, the heat of neutralization of dilute solutions goes with the release of 55.9 kJ / mol of heat....

K=[H+ ][OH-]=[H+]^2=(1.9e-7)^2=3.61e-14

NaCl(1−x) dissociates into Na+(x) and Cl−(x)Total concentration in solution =c(1+x) =0.1M(1+x)Osmotic pressure of NaCl solution =0.1M(1+x) RTOsmotic pressure of urea solution =0.1L (1/60) mol​RTsince solutions are isotonic, therefore, 1+x=1.667(a) Van’s Hoff factor= 1.667(b) Degree of dissociation =x=0.667

Definition (according to https://www.chemguide.co.uk/atoms/properties/ies.html): The first ionisation energy is the energy required to remove one mole of the most loosely held electrons from one mole of gaseous atoms to produce...

5% = 0.05 pH = 14 - pOH pOH = -lg(OH-) = -lg(0.3*0.05) = -lg(0.015) = 1.82 pH = 14 - 1.82 = 12.18
