ASSERTION (A): Generally, ionization enthalpy increases from left to right in a period.

Monjur Alahi

ASSERTION (A): Generally, ionization enthalpy increases from left to right in a period. 

REASON (R): When successive electrons are added tom the orbitals in the same principal quantum level, the shielding effect of inner core of electron does not increase very much to compensate for the increased attraction of the electron to the nucleus. 

(a) assertion is correct statement and reason is wrong statement. 

(b) assertion and reason are both correct statements and reason is correct explanation of assertion. 

(c) assertion and reason both are wrong statement. 

(d) assertion is the wrong statement and reason is the correct statement.

Why the strength of oxyacids formed by nonmetals increases from left to right?

An acid that contains oxygen is called oxoacid. Electronegativity of the central atom and the number of oxygen atoms determines the acidic strength of oxoacid. As the electronegativity increases, acidic strength also increases. As the...

How does electro negativity vary down the group 17 and why? How does it vary from left to right in the period?

Electro negativity decreases down the group due to increase in atomic size. It increases along the period from left to right due to decrease in atomic size. Fluorine (F) has...

How would you explain the fact that the first ionization of Na is lower than that of Mg but its second ionization enthalpy is higher than that of Mg?

The electronic configurations of Na and Mg are: Na:1s2 2s2 2p6 3s1 And Mg: 1s2 2s2 2p6 3s2 thus, the first electron in both the cases has to be removed...

Match the words on the left with a word on the right. Some words on the left can go with more than one word on the right.

(i) a portion of fried fish (ii) a pool of blood (iii) flakes of snow (iv) a huge heap of stones (v) a gust of wind (vi) little drops of water (vii) a piece of cotton (viii) a pot of gold

How and why does the atomic size vary as you go (i) from left to right along a period (ii) down a group ?

(i) Atomic size goes on decreasing from left to right because one proton and one electron is being added successively, therefore, force of attraction between valence electrons and nucleus increases,...

In the Modern Periodic Table how does the metallic trend of the elements change as we move (i) from left to right in a period, and

(i) Decreases (ii) Increases Detailed Answer :  (i) On moving across a period, nuclear pull increases due to the increases in the atomic number and thus the atomic size decreases. Hence, elements...
