AI Generated Solution

To solve the question, we need to analyze both the assertion and the reason provided. ### Step 1: Understanding the Assertion The assertion states that the atomic size of silver (Ag) is almost the same as that of gold (Au). - **Fact Check**: The atomic size (or atomic radius) of silver is indeed very close to that of gold. This is primarily due to the presence of similar electron configurations in these elements, as both are in the same group of the periodic table (Group 11). ### Step 2: Understanding the Reason ...

Assertion : Atomic radius of gallium is higher than that of aluminium Reason : The presence of additional d-electron offer poor screening effect for the outer electrons from increased nuclear charge.

Assertion: Boron has a smaller first ionisation enthalpy than beryllium. Reason: The penetration of a 2s electron to the nucleus is more than the 2p electron, hence 2p electorn is more shielded by the inner core of electrons than the 2s electrons.

Assertion : 4d and 5d series elements have nearly same atomic radius. Reason : Lanthanoid contraction.

Assertion :Bothe Cu^(+) and Na^(+) have almost same radil. Reason : Cu^(+) possesses more power to polarise an anion.

B has a smaller first ionization enthalpy than Be. Consider the following statements (i) it is easier to remove 2p electron than 2s electron (ii) 2p electron of B is more shielded from the nucleus by the inner core of electrons than the 2s electrons of Be (iii) 2s electron has more penetration power than 2p electron (iv) atomic radius of B is more than Be (atomic number B= 5, Be = 4) The correct statements are
