CorrectAnswer: C sw sw




Rationale: Noble gases are s w s w located in Group 8A (also known
sw s w s w




as Group s w 18) of the periodic table.
sw s w s w s w




They are characterized s w s w by having a full
s w valence ele ctron shell, sw




making them very stable and unreactive. Group 7A contains s w




ha logens, Group1A contains
sw s w alkali metals, and Groups w 3A
contains the boron
family.




Question 2: What are covalent bonds?

A) Metallic bonds tend to form between two atoms with similar charges
B) Covalent bonds tend to form between two atoms classified as non-metals
C) Ionic bonds tend to form between two metals

CorrectasAnswer:asB

Rationale: Covalent bonds form when two non-
metal atoms share electrons to achieve stable electron configurations.
Opti on A is sw s w incorrect because metallic bondsinvolvea "sea
of electrons"
s w bet ween metal atoms, sw not similar charges.
Option C is
sw incorrect because io nic
sw sw bonds
form between metals and non-

metals, not two metals. Option D is incorrect because covalent bonds
do not sw typically form between metals and non-
metals.
