b. Tl+, Te2−, Cr3+
c. Pu4+, Ce4+, Ti4+
d. Ba2+, Pt2+, Mn2+
(a)
Interpretation: The ions that shows noble gas configuration is to be identified.
Concept introduction: Nobel gases are those gases which are stable in nature. The electronic configuration gives the representation of distribution of electrons of atoms and molecules. The outer-most shell of these gases is completely filled.
To determine: The ions that shows the noble gas electronic configuration from
Answer to Problem 51E
Explanation of Solution
For
The atomic number of iron
It loses two electrons to form
The outer most shell is not completely filled. Hence, it will not show noble gas configuration.
For
The atomic number of iron
It loses three electrons to form
The outer most shell is not completely filled. Hence, it will not show noble gas configuration.
For
The atomic number of scandium
It loses three electrons to form
The outer most shell is completely filled. Hence, it will show noble gas configuration.
For
The atomic number of cobalt
It loses three electrons to form
The outer most shell is not completely filled. Hence, it will not show noble gas configuration.

Answer to Problem 51E
Explanation of Solution
For
The atomic number of thallium
It loses an electron to form
The outer most shell is not completely filled. Hence, it will not show noble gas configuration.
For
The atomic number of tellurium
It gains two electrons to to form
The outer most shell is completely filled. Hence, it will show noble gas configuration.
For
The atomic number of chromium
It loses three electrons to to form
The outer most shell is not completely filled. Hence, it will not show noble gas configuration.

- paramagnetism is present when an element, ion or molecule has unpaired electrons? true or false and whyarrow_forwardAlthough I3- is a known ion, F3- is not. (a) Draw the Lewis structure for I3- (it is linear, not a triangle). (b) One of your classmates says that F3 - does not exist because F is too electronegative to make bonds with another atom. Give an example that proves your classmate is wrong. (c) Another classmate says F3- does not exist because it would violate the octet rule.Is this classmate possibly correct? (d) Yet another classmatesays F3- does not exist because F is too small to make bonds tomore than one atom. Is this classmate possibly correct?arrow_forward7.50 Chemical species are said to be isoelectronic if they have the same Lewis structure (regardless of charge). Consider these ions and write a Lewis structure for a neutral molecule that is isoelectronic with each of them, (a) CN , (b) NH4+ . (c) CO32arrow_forward
- In Section 12.10 of your text, the term “effective pairs" is used. What does this mean?arrow_forwardIn Section 8.13 of the text, the term effective pair is used. What does this term mean?arrow_forwardWhat is meant by a chemical bond? Why do atoms form bonds with each other? Why do some elements exist as molecules in nature instead of as free atoms?arrow_forward
- Which of the following statements is false concerning bonding? Elements with extremely different electronegativities tend to form ionic bonds with each other. In an N—O bond. electron density is greater near the O atom. An N—O bond is an example of a polar covalent band. In general, chemical bonds form to minimize energy. The bond in KBr is formed by sharing electrons.arrow_forwardWhich of the following statements is/are true? Correct the false statements. a. It is impossible to satisfy the octet rule for all atoms in XeF2. b. Because SF4 exists, OF4 should also exist, because oxygen is in the same family as sulfur. c. The bond in No+ should be stronger than the bond in No. d. As predicted from the two Lewis structures for ozone, one oxygen-oxygen bond is stronger than the other oxygen-oxygen bond.arrow_forwardWhich of the following represent configurations of indium ions in compounds?
