Q. 4.74 - An Introduction to General, Organic, and Biological Chemistry

Question

Which statements completed with a to e will be true and which will be false? An atom of $C$ compared to an atom of $Sn$ has a larger (greater)

a. Atomic size

b. Ionization energy

c. Number of protons

d. Metallic character

e. Number of valence electrons

Step-by-Step Solution

Answer

(a) The given statement is, False

(b) The given statement is, True

(c) The given statement is, False

(d) The given statement is, False

(e) The given statement is, False

Part (a) Step 1: Given information

We are given that the atomic size $C$ atom is larger than that of $Sn$ atom 

Part (a) Step 2: Explanation

We know that,

The $C$ and $Sn$ are in same group but in different period.

As the atomic size increases down the group in the periodic table. 

And $Sn$ lie below the $C$ in periodic table.

So, the atomic size of $Sn$is larger than $C$

Therefore, the given statement is false

Part (b) Step 1: Given information

We are given that the ionization energy of $C$ is larger than that of $Sn$

Part (b) Step 2: Explanation

As we know ionization energy decreases down the group in periodic table and $Sn$ is below $C$ due to which ionization energy of $C$ is larger than that of $Sn$ which is given statement.

Therefore, the given statement is true.

Part (c) Step 1: Given information

We are given that no. of protons in $C$ atom is larger than that in $Sn$ atom.

Part (c) Step 2: Explanation

As we know that atomic no. of $C$ atom is $6$ and $Sn$ atom is $50$

Also, atomic no. is equal to no. of protons.

Hence no. of protons in $C$ atom is, $6$ and that in $Sn$ atom is, $50$

So, no. of protons in $Sn$ atom are greater that $C$ atom

Therefore the given statement is false

Part (d) Step 1: Given information

We are given that metallic character in $C$ atom is larger than that in $Sn$ atom.

Part (d) Step 2: Explanation

As we know that metallic character increases down the group. As $Sn$ is below the $C$ So, metallic character of $Sn$ is larger than that of $C$.

Therefore the given statement is false.

Part (e) Step 1: Given information

We are given that no. of valence electron in $C$ atom is greater than that in 

Part (e) Step 2: Explanation

As we know that $C$ atom and $Sn$ atom lie in the same group Due to which no. of valence electrons are same in both the atoms

Therefore the given statement is false.
